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.
|
||
|
|
|
||
|
|
This 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.
