OpenSSL
A robust, commercial-grade, open-source toolkit for TLS/SSL, DTLS, QUIC protocols and general-purpose cryptography.
What is OpenSSL?
OpenSSL is an open-source toolkit that provides robust implementations of the Transport Layer Security (TLS), Datagram TLS (DTLS), and QUIC protocols along with a comprehensive cryptographic library. It solves the fundamental need for secure communications across networks by offering commercial-grade encryption and protocol support that powers much of the internet's security infrastructure.
System administrators, security engineers, and developers who need to implement secure communications in applications, servers, or infrastructure components requiring TLS/SSL, DTLS, or QUIC protocol support.
Developers choose OpenSSL because it provides a battle-tested, comprehensive cryptographic toolkit that's freely available and open source, with support for the latest security protocols and FIPS validation for regulated environments.
