%description
    The scrypt key derivation function was originally developed for
    use in the Tarsnap online backup system and is designed to be far
    more secure against hardware brute-force attacks than alternative
    functions such as PBKDF2 or bcrypt. A simple password-based
    encryption utility is available as a demonstration of the scrypt key
    derivation function. 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.
