Asking for donation sound bad to me, so i'm raising fund from by offering all my four cryptography book for just $9
Bcrypt is a password hashing function designed by Niels Provos and David Mazières, based on the Blowfish cipher. BCrypt was first published, in 1999, they listed their implementation's based default cost factor,This is the core password hashing mechanism in the OpenBSD operating system
The bcrypt workload is specified in the above static variable, a value from 10 to 31. A workload of 12 is a very reasonable safe default as of 2013.
A bcrypt cost of 6 means 64 rounds (2^6 = 64).
for example given bcrypt hash Value
$06$specifies a cost parameter of 6, indicating 64 key expansion rounds
128 bit salt
is the resultinh hash
bcrypt Output size is fixed: 192 bits.
