- Defined in:
- lib/authlogic/crypto_providers/sha512.rb
Overview
SHA-512 does not have any practical known attacks against it. However, there are better choices. We recommend transitioning to a more secure, adaptive hashing algorithm, like scrypt.
Class Attribute Summary collapse
-
.join_token ⇒ Object
Returns the value of attribute join_token.
-
.stretches ⇒ Object
The number of times to loop through the encryption.
Class Method Summary collapse
-
.encrypt(*tokens) ⇒ Object
Turns your raw password into a Sha512 hash.
-
.matches?(crypted, *tokens) ⇒ Boolean
Does the crypted password match the tokens? Uses the same tokens that were used to encrypt.
