OpenSSL Library

The OpenSSL software library is a robust, commercial-grade, full-featured toolkit for general-purpose cryptography and secure communication. It is a fundamental open source component in the global digital infrastructure, widely used by both open source projects and commercial software. OpenSSL provides implementations of several highly important security protocols and standards, including TLS (formerly known as SSL), DTLS, CMS, and QUIC. OpenSSL implements a wide variety of different cryptographic algorithms (including encryption, hashes, key exchange/encapsulation, signatures, key derivation, message authentication codes, etc.) as well as other supporting functionality (such as digital certificates, key generation and key storage). OpenSSL is a mature, battle hardened product that has undergone multiple code audits and stood the test of time since its inception in the 1990s. It contains within it our FIPS provider, a cryptographic module that has undergone the rigorous and extensive FIPS 140-2 validation process. Our seasoned security team is well equipped to professionally and responsibly deal with emerging threats to keep our users safe. The features and capabilities described above represent critically important building blocks that other applications can use to ensure the confidentiality, integrity and authenticity of data they store, transmit and receive. Countless technologies are built with OpenSSL on the back end. It is invisible to end users but nonetheless vital to global digital infrastructure.
