Hello,
I want decrypt a password which is encrypted by MD5.
there are 4 functions which i am using :
# Encrypts some data with the salt.
def self.encrypt(password, salt)
Digest::SHA1.hexdigest("--#{salt}--#{password}--")
end
# Encrypts the password with the user salt
def encrypt(password)
self.class.encrypt(password, salt)
end
def authenticated?(password)
crypted_password = encrypt(password)
end
def encrypt_password
self.salt = Digest::SHA1.hexdigest("--#{Time.now.to_s}--#
{login}--") if new_record?
self.crypted_password = encrypt(password)
end
please do tell me...

Perhaps, you should try some other lists for your code which is unrelated to Rails itself in the future. In any case, MD5 is a hashing algorithm and a one-way function. Meaning, once you get a hash, there is no way to get the original data back. Also, in the code snippets that you gave, you are using SHA1: which is completely different from MD5.

First, it''s not possible. The only reason you''d want to do this if you have access to the DB is if you''re a hacker. Second, this isn''t a list for this kind of question - that''s what rails-talk is for. --Matt Jones -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Core" group.
