Module BcryptSource
Module for safe salting and hashing of passwords using the Bcrypt algorithm.
Exceptions
The provided count is invalid. The count must be an integer between 4 and 31, inclusive.
The given string seed cannot be used as seed. Please provide a string at least 16 bytes long.
An exception occurred obtaining random seed from /dev/urandom.
An exception occurred in backend's _crypt_gensalt_blowfish_rn function.
An exception ocurred in backend's _crypt_blowfish_rn function.
Type definitions
Abstract type holding a password in salted and hashed form. Use function hash to generate a hash.
Supported variants of the Bcrypt algorithm.
Public functions and values
Call hash ?count ?variant ?seed password to hash the given password string. The password is automatically salted before hashing. If seed is not given, the salting procedure automatically fetches a seed from /dev/urandom. If given, seed must be a string at least 16 bytes long. The count parameter is the log2 number of Blowfish iterations to use in the hashing procedure. Its default value is 6, and any integer between 4 and 31 (inclusive) may be used. Finally, variant picks which of the Bcrypt variants to use (defaults to Y).
Call verify password hash to verify if the given password matches the previously hashed password.
