All of our computers after a recent update disabled SSL 2.0 and 3.0 and enabling SSL 3.0 did not help. SSL 2.0 is the only security protocol we can use to access the site. I went to the internet options to re-enable SSL 2.0 and it was gone. I searched the entire list, tried Chrome, Edge, IE9 and firefox and could not find any way. OpenSSL: open Secure Socket Layer protocol Version. The OpenSSL Project is a collaborative effort to develop a robust, commercial-grade, full-featured, and Open Source toolkit implementing the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols as well as a full-strength general purpose cryptography library.

Microsoft recommends disabling SSL 2.0 and SSL 3.0 due to serious security vulnerabilities in those protocol versions. Customers may also choose to disable TLS 1.0 and TLS 1.1 to ensure that only the newest protocol version is used. However, this may cause compatibility issues with software that doesn't support the newest TLS protocol version. Resources and libraries for interacting with certificates, keys, passwords, and dhparam files. Openssl Cookbook CHANGELOG. Although SSL 2.0 was publicly released, it also contained security flaws and was quickly replaced by SSL 3.0 in 1996. Then, in 1999, the first version of TLS (1.0) was released as an upgrade to SSL 3.0.

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. All older versions (including 1.1.0, 1.0.2, 1.0.0 and 0.9.8) are now out of support and should not be used. Users of these older versions are encouraged to upgrade to 1.1.1 as soon as possible. Extended support for 1.0.2 to gain access to security fixes for that version is available.

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.

OpenSSL 3.0 is the next major version of OpenSSL that is currently in development and includes the new FIPS Object Module. A pre-release version of this is available below. This is for testing only. It should not be used in production. Information and notes about OpenSSL 3.0 are available on the OpenSSL Wiki

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 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.
