HowTo: Decrypt a File $ openssl enc -aes-256-cbc -d -in -out file.txt Options When the salt is being used the first eight bytes of the encrypted data are reserved for the salt: it is generated at random when encrypting a file and read from the encrypted file when it is decrypted. The reason for this is that without the salt the same password always generates the same encryption key.
