The master sources are maintained in our git repository, which is accessible over the network and cloned on GitHub, at https://github.com/openssl/openssl. Bugs and pull patches (issues and pull requests) should be filed on the GitHub repo. Please familiarize yourself with the license.
The table below lists the latest releases for every branch. (For an explanation of the numbering, see our release strategy.) All releases can be found at /source/old. A list of mirror sites can be found here.
Note: The latest stable version is the 1.1.1 series. This is also our Long Term Support (LTS) version, supported until 11th September 2023. Our previous LTS version (1.0.2 series) will continue to be supported until 31st December 2019 (security fixes only during the last year of support). The 1.1.0 series is currently only receiving security fixes and will go out of support on 11th September 2019. All users of 1.0.2 and 1.1.0 are encouraged to upgrade to 1.1.1 as soon as possible. The 0.9.8, 1.0.0 and 1.0.1 versions are now out of support and should not be used.
The OpenSSL FIPS Object Module 2.0 (FOM) is also available for download. It is no longer receiving updates. It must be used in conjunction with a FIPS capable version of OpenSSL (1.0.2 series). A new FIPS module is currently in development.

When building a release for the first time, please make sure to look at the INSTALL file in the distribution along with any NOTES file applicable to your platform. If you have problems, look at the FAQ, which can be found online. If you still need more help, then join the openssl-users email list and post a question there.
PGP keys for the signatures are available from the OMC page. Current members that sign releases include Richard Levitte and Matt Caswell.
Each day we make a snapshot of each development branch. They can be found at https://www.openssl.org/source/snapshot/. These daily snapshots of the source tree are provided for convenience only and not even guaranteed to compile. Note that keeping a git local repository and updating it every 24 hours is equivalent and will often be faster and more efficient.
Please remember that export/import and/or use of strong cryptography software, providing cryptography hooks, or even just communicating technical details about cryptography software is illegal in some parts of the world. So when you import this package to your country, re-distribute it from there or even just email technical suggestions or even source patches to the authors or other people you are strongly advised to pay close attention to any laws or regulations which apply to you. The authors of OpenSSL are not liable for any violations you make here. So be careful, it is your responsibility.
