Hi,

Can anyone tell me the hash encryption level for a password using acts  
as authenticated 128bit, 164bit???

require ‘digest/sha1’

# Encrypts some data with the salt.

def self.encrypt(password, salt)  
Digest::SHA1.hexdigest("–#{salt}–#{password}–")  
end

JB

Correct me if I’m wrong, imho it doesn’t have an encryption level  
since hashing is one-way…  
A sha1 hash is 40 alnum characters (160 bit) long.
