Class Attribute Summary collapse
- .join_token ⇒ Object
-
.stretches ⇒ Object
The number of times to loop through the encryption.
Class Method Summary collapse
-
.encrypt(*tokens) ⇒ Object
Turns your raw password into a Sha1 hash.
-
.matches?(crypted, *tokens) ⇒ Boolean
Does the crypted password match the tokens? Uses the same tokens that were used to encrypt.
