On modern hardware and with default +parameters, the cost of cracking the password on a file encrypted by scrypt +enc is approximately 100 billion times more than the cost of cracking the same +password on a file encrypted by openssl enc; this means that a five-character +password using scrypt is stronger than a ten-character password using openssl. |
