Summary

Picolisp wrapper for the bcrypt library (blowfishhashing algorithm only at the moment).

Get bcrypt

Run the included compile script.

Usage

Load library

(load "bcrypt.l")

The path to the bcrypt library is set with bcrypt~*Lib, defaults to ./bcrypt.so.

Generate hash

Use the generate-hash method:

: (bcrypt~generate-hash 5 "Secret")
-> "$2b$05$xGVeqJGU728knKkN6Hoyiee/kTO6WhG5UcsEcTI8txyP2hZUhVR16"

It requires the number of iterations for the algorithm. As a rule of thumb it should be the highest number that achieves the hashing in less than a second.

Compare password with hash

Use the compare-with-hash method:

: (bcrypt~compare-with-hash "Secret" "$2b$05$xGVeqJGU728knKkN6Hoyiee/kTO6WhG5UcsEcTI8txyP2hZUhVR16")
-> T
