Rails Login with MD5
I am working on migrating an existing system that utilizes MD5 rather than SHA1 for password encryption so I needed to make a few adjustments to the login process.
I had issued the following command which created some objects to work with../script/generate login User
My existing system also uses the email address as the login username, so I modified the the file ./app/models/user.rb:
I changed this:def self.sha1(pass) Digest::SHA1.hexdigest("---changme--#{pass}--") endto:
def self.md5(pass) Digest::MD5.hexdigest("--my-salt--#{pass}") end
Then I went and changed instances of sha1 in user.rb to md5.
The next step was to modify the field that authentication was checking the database with.
I changed this:def self.authenticate(login, pass) find_first(["login = ? AND password = ?", login, sha1(pass)]) endto this:
def self.authenticate(login, pass) find_first(["email = ? AND password = ?", login, md5(pass)]) end
The last step was to modify the table that the system looks in for the users who can login to the system. Still in user.rb, I added this to the top of the User class.
class User < ActiveRecord::Base def self.table_name() "employees" end ... end
