{{redirect|Secure Transport|the transportation of valuables|Armored car (valuables)}}
The [[Transport Layer Security]] (TLS) protocol provides the ability to secure communications across or inside networks. This '''comparison of TLS implementations''' compares several of the most notable [[software library|libraries]]. There are several TLS implementations which are [[free software]] and [[Open-source software|open source]].

Note that there are known vulnerabilities in SSL 2.0 and SSL 3.0. In 2021, IETF published RFC 8996 also forbidding negotiation of TLS 1.0, TLS 1.1, and DTLS 1.0 due to known vulnerabilities. NIST SP 800-52 requires support of TLS 1.3 by January 2024. Support of TLS 1.3 means that two compliant nodes will never negotiate TLS 1.2.
