OpenSSL is an open-source cryptographic toolkit and security project for TLS, Datagram TLS (DTLS), and QUIC, developed by the OpenSSL Project. It includes libssl, implementing TLS and DTLS through version 1.3 and QUIC version 1; libcrypto, a general-purpose cryptographic library usable independently; and the openssl command-line tool for key generation, X.509 certificates, CSRs and CRLs, message digests, encryption and decryption, protocol testing, and S/MIME operations. OpenSSL also provides implementations of the post-quantum algorithms ML-DSA and ML-KEM, includes a cryptographic module validated to conform with FIPS standards, and is licensed under the Apache License 2.0. The project distributes source code, maintains a public GitHub mirror, and is commonly provided as precompiled binaries by operating-system vendors.
