[openssl-users] different encrypted text for the same plain text message

There are several places where a per-connection random input is
introduced, with a specific goal of making encryptions of the same
plaintext produce different ciphertexts (as well as other benefits). If
a plaintext always produced the same ciphertext, then an attacker could
make a dictionary of different observed ciphertexts and know when the
same plaintext was being repeated, which violates the confidentiality
property desired from the protocol.
