Open Source Alternatives to OpenSSL
What is OpenSSL?
OpenSSL is a robust, full-featured toolkit for the Transport Layer Security (TLS) and Secure Sockets Layer (SSL) protocols, providing cryptographic libraries and command-line tools.. There are currently 8 open-source alternatives to OpenSSL, with a combined total of 23.3k GitHub stars. The most common language among these projects is C.
