A Clojure library for securing user passwords using a key derivation function. Supports the following algorithms:
Add the following dependency to your
Pick an encryption algorithm, either
(require '[crypto.password.<algorithm> :as password])
Then use the
encrypt function to apply a secure, one-way encryption
algorithm to a password:
(def encrypted (password/encrypt "foobar"))
check function to check the encrypted password against a
(password/check "foobar" encrypted) ;; => true
The default options for the key derivation algorithms were chosen based on benchmarks carried on on a AWS t1.micro server running Ubuntu 13.10 (ami-35dbde5c), in March 2014.
On this hardware, the key derivation functions take approximately 200ms to complete with their default options. This is a short enough time to not be an inconvenience for a human being, but long enough to make brute forcing encrypted passwords very costly.
