Geo Restriction Lets You Control Where Your Content Can Be Downloaded From

geolocation1When you publish software for distribution on Bintray, you generally want to give it as wide a reach as possible and expose it to as many potential users as you can. But there are also cases in which you have to restrict access to certain countries. For example, government security or export regulations may forbid you from doing business with certain countries, or your own company may even restrict your particular organization to distributing your software in your own local region of the world. This is where Bintray’s Geo Restriction feature saves the day.

White lists and black lists

Bintray’s Geo Restriction feature works by letting you define a whitelist or a blacklist per repository. If you create a whitelist, only users from countries entered in the list will be able to download software from the repository. A black list works the opposite way; users from countries in the list are forbidden from downloading software. Bintray determines where a download request is coming from by passing the request IP to a GeoIP provider who determines the country from which the request originated. Then, if a Geo Restriction is applied to the target repository, Bintray will make sure the request can be honored according to the whitelist or blacklist defined. For download requests from countries restricted from accessing a repository, Bintray will respond with an error.

Geo Restriction is available for repositories in an Enterprise account. Gold account users can also see how this feature works, but are limited to one country in the list.

It’s so easy

You can define a whitelist or blacklist by selecting the Geo Restriction tab in the Edit Repository page for each of your repositories. Note that you can only edit the repository if you own it, or if it’s owned by an organization of which you are a member and have the required authorization to do so.


Geo restrictions come first

A Geo Restriction overrides any other form of “permission” in Bintray. In other words, even if a user is a member of your team and has “permission” to download a file, or even if you’ve provided someone with a signed URL or an entitlement  to download a file, if their request comes from a restricted country, it will be blocked.



Keep Your Secrets Safe by Serving Encrypted Files

encrypted_280x215aOnce you have uploaded your content into Bintray private repositories, it’s pretty safe through Bintray’s management of users, organizations, and teams. But what happens when you need to send a private file to someone else? Signed URLs give you an easy way to do that. Just generate your URL signing key and use the URL signing API call to create the URL. You can even make the URL valid for only a limited period of time. Now all you need to do is send the URL to the right person.

But what happens if the URL or the downloaded file gets into the wrong hands? Suddenly the file containing a license key/sensitive company information/anything-else-you-badly-wanted-to-keep-private is exposed..

Well, worry no more.  Bintray can now protect you from that kind of unwanted exposure.

On-the-fly file encryption

Bintray can now encrypt your file, on-the-fly, before it is downloaded through the signed URL. It works like this:

  • Upload your file (either manually through the website or using the REST API) into one of your private repositories.
  • Now you can generate the signed URL which will download the file.
    Nothing new yet, but here’s the thing.
    Now you can also attach a secret to the signed URL and tell Bintray to encrypt the file before it is downloaded. Bintray uses AES 256 CBC encryption for which you can provide your own secret key or ask Bintray to create one for you.
  • Now you can provide your customer with your secret through an alternative communications channel.
  • Once your customer has downloaded the file, they can use the secret key to decrypt the file using an OpenSSL command line. In other words, they need both the signed URL and the secret key.

Let’s See It In Action

Let’s assume we have a top secret “message.txt” file in a repo. We’ll use the REST API to create the signed URL:

curl -X POST -H "Content-Type: application/json" --data '{"valid_for_secs": 3600, "secret" : "my secret"}'

200 OK
"url": ""

If you don’t supply a secret, Bintray will create one for you and return it as an Http header: X-Bintray-Secret. Note that for that extra bit of security we limited the validity of the URL to 3600 seconds.

Your customer can now download the file from the returned URL:

curl -o message.txt ""

You can choose any secured way to send the user the secret. For example: phone or text message.

Now, to decrypt the file, your customer can use OpenSSL:

$ openssl enc -aes-256-cbc -d -in <encrypted file name> -out <decrypted file name output>

The tool will prompt your customer for the secret and then proceed to decrypt the file.

That’s how you keep your secrets safe. Enjoy!







Who needs a EULA if nobody reads it?

bintray_eula_products_blogpostAs long as you’re distributing public open source software, you don’t need a EULA. Just choose from the over 100 open source licenses Bintray offers to get the level of protection you want. Once you move to distributing commercial software, you need a EULA. This is the contract that you make with all of your users when they download your software from Bintray. Without a EULA, you’re exposing yourself to lawsuits and unmitigated copying and redistribution.

Now, we’ve all seen EULAs. Whether they’re entitled “Terms of Service”, “Terms and Conditions”, or “Here’s what you can and can’t do with my software”, essentially, they are the same. They usually pop up early on in the installation sequence of any new piece of commercial software we install. And I can tell you, with 5-nines of certainty that most of us just click “Next” without reading them, and complete the installation. But there is a breed of people who actually DO read EULAs. They are usually sequestered in some corporate enclave, and it’s their job to make sure that the company they represent can accept the contractual obligations you set forth in your EULA. Yes, these are the company lawyers. Without their “OK”, your potential enterprise customers will not use your software.

Now, as smart as lawyers may be (or not), if your EULA is hidden somewhere deep under /etc/this/that/and/the/other, it’s going to be difficult to find. There’s no reason to make this difficult. Bintray gives you an easy way to expose your EULA through Products.

Bintray Products and EULAs

Say you developed your “packageOfTheCentury”, and, naturally, you want to offer it to developers on different platforms. I.e., you might have your debianPackageOfTheCentury, nugetPackageOfTheCenutury, npmPackageOfTheCentury…and so on. Since all these packages represent the same product, just for different packaging formats, you will want to apply the same EULA to all of them. This is where Bintray Products come into play. Products are available with a Gold or Enterprise account, and let you collect all the packages under one roof as a single coherent offering, making it easy for you to manage. It’s also easier for potential users to find your single product rather than searching for all its components separately, and any update you make to any of the constituent packages in your product is automatically reflected as a new version of the product itself. But the biggest benefit is that you only need to assign a single EULA to your product, and it applies to all of its constituent packages. And the beauty of it is that your EULA protects your product, for both authenticated and anonymous users, before it’s even downloaded, rather than being embedded inside the packages. That also means that it’s easy to update online as any of the constituent packages are updated with new versions. 

Creating a Product is easy.



And once your product is created, and you’ve entered its basic details, it’s easy to add packages to it.


You don’t even have to change your product’s version manually; it is automatically derived by Bintray any time the version of one its constituent packages changes. And if you really want to, you can assign a different EULA to different versions of your product as needed.You don’t even have to change your product’s version manually; it is automatically derived by Bintray any time the version of one its constituent packages changes. And if you really want to, you can assign a different EULA to different versions of your product as needed.

Product Versions


All About Bintray EULAs

With a Bintray Enterprise account, you can manage all of your EULAs in one place and set a default EULA to be assigned to all new versions of this product that are created.


You can create a new EULA at any time using Asciidoc, Markdown or free text.

Create a New EULA

And once you have a EULA assigned to your product, if anyone (even an anonymous user) tries to download a file from one of the packages in your product, they will have to accept your EULA first. In fact, the download URL provided by Bintray for any of the packages in your product will first pop up the EULA and require the user to accept before proceeding with download. That means you can provide a EULA-protected download link from any other app. Just hover over the package in your download list to see it.

Download URL with EULA


Why don’t you try this one to see how it works. Here’s what you should see.

Accept EULA


By collecting the different packages you are offering under a single product, governed by a single EULA, you’re protecting your interests, making things simpler, and reducing your (and your customers’) legal costs. Can you think of any better way to protect your IP and keep both your lawyers and your customers happy?

6 Reasons to Distribute Commercial NuGet Packages through Bintray

Developing on .NET? Then, most likely, you are no stranger to NuGet Gallery. It’s a great place to find public NuGet packages. But is it the best place to host and distribute your own private packages? With the recent addition of native support for NuGet, you can now point your NuGet client to Bintray and transparently use it as your download source for NuGet packages. In this post, I’ll show how Bintray complements NuGet Gallery and the benefits it offers for the commercial distribution of private and public NuGet packages.

Privacy with fine-grained access control

With a professional account on Bintray, you can create private repositories and set up teams of users with different permissions according to the access you want to provide each team. Using keys and entitlements, you can provide external users who don’t have a Bintray account access at any level of granularity, from a whole repository down to a single artifact.


On Bintray, every package is accompanied with a variety of metadata that can be used to search for and download packages. These include owner, open-source licenses used by the package, link to version control where the package’s sources can be found, even user-defined attributes and more.

Rapid downloads

Bintray is deployed on US, European, and Asian clusters and provides ultra-fast downloads over a rapid CDN (Akamai and Cloudfront).

Rich stats and logs

Rich stats provide detailed download information over any time period, and live logs provide detailed information about who is accessing your packages.

Integration with Artifactory

Bintray’s tight integration with Artifactory means that you can fully automate your .NET development pipeline from development to distribution.

A universal distribution hub

Bintray can serve your enterprise distribution needs for all package types. In addition to NuGet, Bintray also offers native level support for Docker, Debian, Maven, RPM, and Vagrant packages. This means that Bintray maintains metadata specific to these package types and can work transparently with the corresponding clients.

How does it work?

It’s pretty simple really.

First, create a repository and specify its type to be NuGet.

Create a NuGet repository

Now, all you need to do is point your NuGet client or Visual Studio at your new repository on Bintray. That’s just as easy, and Bintray even shows you how to do that. On your new repository page, just click Set Me Up. For the sake of readability, on this post, I’ll be using the NuGet client.

Set up a NuGet Repository

So, like the Set Me Up dialog shows us, to configure the NuGet client to work with Bintray, you need to add Bintray to the client’s list of sources:

nuget sources Add -Name Bintray -Source -UserName <USERNAME> -Password <API KEY>


As you can see, you’ll need to include your Bintray username and API Key.

Then, you need to enable the use of your Bintray API key with the NuGet client:

nuget setapikey <USERNAME>:<APIKEY> -Source Bintray


Now you’re ready to deploy packages from the NuGet client directly to bintray. As an example, let’s say you want to upload a great logging utility you created called MyLogger (yes, I’m keeping things simple). Are you used to using nuget push? Well, nothing has changed:

nuget push MyLogger. -Source


Now you should be able to see your package in your new NuGet repository, complete with the version you assigned.

Resolving NuGet package

And resolving the NuGet package from Bintray with the NuGet client is just as easy:

nuget install MyLogger -Source


As you can see, once you have added Bintray as a source for your NuGet client, you can push and install transparently as if you were working with the NuGet Gallery. And since Bintray is a universal distribution hub, you can push to and pull from Bintray with the same ease when working with Docker, Debian, RPM, Maven, and Vagrant using the corresponding client for those package types. And with generic repositories on Bintray, you can host generic distributions such as installers or data files with the same ease of use. As we continue to add support for more and more package types, working with Bintray will just continue to get easier.

Manage your Bintray and GitHub organizations better together

Bintray’s integration with GitHub is now moving to a new level with GitHub organizations! As a Bintray user who is also a GitHub user, you already know that you can import your GitHub repositories, tags, readme’s, and release notes to Bintray. Now you can also import your GitHub organizations, the organization’s repositories, and even keep your GitHub and Bintray organization’s members in sync! This new feature saves time and effort maintaining your organizations and their members across the two platforms.

Here’s how to do that:

Authorize your GitHub account in Bintray

In order to be able to import GitHub entities to Bintray, your GitHub account should be authorized in Bintray. Your GitHub username has to be provided and authorized in the ‘Accounts’ page in your Bintray profile page:

Authorize Github in Bintray

Grant Bintray access to your GitHub organizations

GitHub organizations should be authorized with Bintray, so Bintray is able to access your GitHub organization. Grant Bintray the access by going to your GitHub profile. Under the ‘Applications’ section you will see the GitHub organization. Select the organizations you would like Bintray to be able to access.


You can read more about application authorization with GitHub in the Bintray documentation.

Import a GitHub organization

You can import a GitHub organization while you create a new one in Bintray, or to an existing Bintray organization at any time.

Import GitHub organization to a new Bintray organization

When creating a new organization in Bintray you now see a new option to import your organization from GitHub:

Create new organization

If you choose ‘Import from GitHub’, your GitHub organizations, that have not been imported yet, will be displayed for you to choose from:

Select Organization to Import upon new organization creation

Once you make a selection, your GitHub organization is successfully imported to Bintray. Note that at this point, only the organization is imported, without members or repositories.

At this point Bintray offers you shortcuts to the most common options you naturally wish to do now:

Organization was created successfully

I will elaborate on how to sync members to your imported organization, and how to import an organization repositories later on in this post.

Import GitHub organization to an existing Bintray organization

To associate an existing Bintray organization with a GitHub organization, access the ‘Accounts’ section in your Bintray organization’s profile page. Bintray lets you choose from your accessible GitHub organizations:

Select organization to import to an existing organization

Sync members

Bintray Professional accounts can also sync members from a GitHub organization and have membership changes in a GitHub organization automatically synced to the equivalent Bintray organization. To sync members automatically, click on the ‘Sync’ button in the ‘Members’ section of the organization profile page:

Sync members

The sync will generate an invitation in each member’s Bintray mailbox. Once a user approves his membership, he becomes a fully synced member in the Bintray organization.

The following rules apply once your GitHub organization is imported:

  • All GitHub organization members will be members in the corresponding Bintray organization (as long as they are users of both).
  • GitHub teams are now teams in the corresponding Bintray organization.
  • Members’ permissions are also imported: an ‘owner’ in a GitHub organization will be an ‘admin’ in Bintray, a ‘member’ in GitHub stays a ‘member’ in Bintray.
  • Member’s privacy attributes, ‘private’ and ‘public’ in GitHub, are kept as ‘public’ and ‘nonpublic’ in Bintray .

You can keep the members list synced with Github, so any member added to or removed from GitHub in the future will automatically be updated in your Bintray organization. This saves you the worry of maintaining members in both Bintray and GitHub. You can also disable member sync, so that it is a onetime procedure. Members’ syncing can be enabled or disabled at any time.
For a step by step instructions of how to import GitHub organizations and members, please refer to the user manual.

Import a repository

At this point it makes sense to add a repository to your new organization. Importing GitHub organization repositories is now available! (previously, it was only possible to import personal repositories). In order to do so, create a new repository under your imported organization. In the repository page, click on ‘Import from GitHub’:

Repository page import from GitHub
Bintray will display all the GitHub repositories and their release tags under the imported organization:

Import GitHub repositories

Select the repositories and releases you wish to import, and remember that GitHub repositories will be Bintray packages, and GitHub release tags will be versions in Bintray. Note that the import includes the repository structure and not the actual files.

You can read more about importing GitHub repositories here.

If you use both GitHub and Bintray, this cool new feature will save you time and reduce hassle.
Good Luck!

Catch that Millionth Download with Bintray’s New Statistics API

Want to know exactly how many times your packages have been downloaded? Bintray has always given you download statistics through its UI, but now you can also get them for professional repositories via REST API. Detailed statistics on downloads per version over any time frame give you deep insights into how your software releases are consumed.
If you have never used statistics in Bintray, go ahead and check it out in the user guide.

Let’s see an example
Say I want to get the daily number of downloads of ‘myCoolPackage’ from October 1st to October 8th, 2015. This is what the stats look like in the Bintray UI:

myCoolPackage Downloads UI Stats Per Week

According to the chart, ‘myCoolPackage’ was downloaded a total of 147,752 times in that period. We can clearly see that there were downloads every day; there were dips on October 4th (Sunday) and October 8th (the chart was generated on October 8th around midday), and the most popular versions were 1.1.0 and 1.2.0.

Now you can get all this information programmatically using the new REST API. Here’s the “daily downloads” API as it is described in the REST API documentation:

GET /packages/:subject/:repo/:package/stats/time_range_downloads

To get the statistics displayed in the chart above, I would use the following command:

curl -X GET "" -u tamarUser:***my-top-secret-api-key*** -H "content-type:application/json" -d “{\"from\":\"2015-10-01T12:08:56.235z\",\"to\":\"2015-10-08T12:08:56.235z\"}"

I get the following response in JSON format:


The response provides all of the same data that Bintray uses to create the chart in the UI. For each day within the requested date range in which downloads occurred, it lists the number of downloads per version. As simple JSON output, you can easily parse the response and use it any way that helps you analyze your package downloads quickly and effectively. You are now able to identify trends in downloads, your popular versions and more.

Other statistics REST APIs include: total downloads and downloads by country. Keep an eye on this blog to hear about new APIs when we add them.

Good luck!

Increase your Maven Package’s Exposure by Adding it to JCenter

If you already distribute your Maven packages via Bintray, your packages can gain further exposure by including them in Bintray’s JCenter! (if you are not very familiar with Bintray’s support for Maven, please refer to the user guide and to my previous post).

JCenter is the repository with the biggest collection of Maven artifacts in the world. And it’s on the best software distribution platform around – Bintray. This is where you want your Maven packages to be! CDN speed, user exposure, and live statistics to monitor the use of your artifacts are some of the benefits you get from JCenter. And if you really want to, you can also have your project synced with the older Maven Central repository.

Submit an Inclusion Request to JCenter

To promote sharing of packages within the developer community, once you have uploaded a package to one of your repositories, you can submit a request to the owner of any other repository to have your package included in theirs. If your request is granted, your package can be found just like any other package in that repository. You still maintain full control over the package in your own repository, and any changes you make to it, such as delivering new versions, or even removing it, are automatically synced to the other repository in which it’s included. So to maximize exposure of your Maven package in Bintray, all you need to do is request to have it added to JCenter.
In order to submit a request, just click on the ‘Add to JCenter’ button:

Add Package To JCenter
Once a Bintray moderator approves your request, your package will be available on JCenter, and you will receive a message into your Bintray mailbox. You will also see that your package is now linked to JCenter:
Maven Projects Linked To JCenter

Sync with Maven Central

At this point you can also have JCenter sync your package to Maven Central if you need to serve frameworks still using this repository. All you need to do is click on the ‘Maven Central’ link as shown above. Remember that you need to provide your Sonatype user name to Bintray before the syncing, but don’t worry, Bintray will remind you to do so if you haven’t already added it to your profile under Accounts:
Accounts Sonatype
Bintray takes care of the rest. Please also refer to the step by step instructions for how to sync your artifacts with Maven Central.

Good luck, and keep your package front and JCenter!
