OpenSSL is a library developed by the OpenSSL Project to provide open-source SSL and TLS implementations for the encryption of network traffic.

It is readily available for a variety of Unix-based distributions and can be used to generate certificates, RSA private keys, and perform general cryptography-related tasks.
