Class Authlogic::CryptoProviders::Sha1
In: lib/casserver/authenticators/authlogic_crypto_providers/sha1.rb
Parent: Object

This class was made for the users transitioning from restful_authentication. I highly discourage using this crypto provider as it inferior to your other options. Please use any other provider offered by Authlogic.

Methods

digest   digest_format=   encrypt   join_token   matches?   stretches  

Attributes

join_token  [W] 
stretches  [W] 

Public Class methods

digest(tokens)

This is for "old style" authentication with a custom format of digest

encrypt(*tokens)

Turns your raw password into a Sha1 hash.

join_token()

11:           @join_token ||= "--"
12:         end
matches?(crypted, *tokens)

Does the crypted password match the tokens? Uses the same tokens that were used to encrypt.

    # File lib/casserver/authenticators/authlogic_crypto_providers/sha1.rb, line 53
53:         def matches?(crypted, *tokens)
54:           encrypt(*tokens) == crypted
55:         end
stretches()

The number of times to loop through the encryption. This is ten because that is what restful_authentication defaults to.
