Web22 de fev. de 2024 · A solution I can imagine is to compute the IV from the key AND from the Salt. That would guarantee the uniqueness of the ciphertext AND the recovery of the plaintext by the recipient. If that is the real solution, I wonder what exactly the algorithm from (Key, Salt) to (IV) is and how the result is embedded in the ciphertext. – diciotto.

WebThe -salt option should ALWAYS be used if the key is being derived from a password unless you want compatibility with previous versions of OpenSSL. Without the -salt option it is possible to perform efficient dictionary attacks on the password and to attack stream cipher encrypted data. WebOpenSSL uses this password to derive a random key and IV. This key will be used for symmetric encryption. If you don’t believe me, scroll up and see if the secret password (32 bytes) and the key used are same (they’re not!)
