similar to: de-crypting Ruby password with php.

Happy New Year everyone. Just wondering if anyone has coded the ability to allow a user to change their password following the way the book (second edition) implements administration. Seems like I should be able to cut out the password/password_confirmation portion of ''add_user'' form to create a ''change_pass'' form. The problem is I''m not sure how to go

I admit I am stuck. I am converting a legacy php site to ROR. The old site uses MD5, a security flaw waiting to happen. I upgraded to AAA and am adding code in the session_controller.rb file to see if crypted_password is blank. If it is, crypt and check the password against the old md5 version and write it in the new crypted_password field. Here is my code add on before the logged_in?: def

hi all, i''m learning rspec and i can''t figure out how to test if a callback is executed in a model. my model code is: class User < ActiveRecord::Base before_save :encrypt_password ... def encrypt(password) self.class.encrypt(password, salt) end thanks a lot, cs. -- Posted via http://www.ruby-forum.com/.

I''m in the process of creating a sign up form for an online application. The form collects account info, company info, and then info for an administrative user. The method looks like this: def create @account = Account.create!(params[:account]) @company = @account.companies.create!(params[:company]) @user = @company.users.create!(params[:user]) end However, this inevitably fails

Hello -- I would like to setup a system where a user can generate a "ticket". This ticket will be stored indefinitely. The ticket will be sent to someone who does not have an account on the system and therefore, I would like to ensure some level of security in that ticket number. Basically, the other user would receive an email like: --- Please click on the link below to view this

Hi, I have user add/edit forms.While creating a user I tried the following method to encrypt password and stored the encrypted password in the table. def self.sha1(pass) Digest::SHA1.hexdigest("#{salt}--#{pass}--") end But when I try to edit the page I get the encrypted password in the password field instead of the decrypted password. Is there any method to decrypt

Hey all, I understand that a def self.abc, for example, is a class method, which allows you to call its contents by just referencing model.abc (rather than model.new.abc). However, what is its role when located in a method inside a model like in the code below. Also in the code below, you see :: located in the method. Isn''t that used for modules and namespaces? If so, why is it located

what i have done is as follows password = Digest::SHA1.hexdigest("#{salt}:#{password}") pass1 = Digest::SHA1.hexdigest("#{salt}:asdfgh") pass2 = Digest::SHA1.hexdigest("#{salt}:asdfgh") pass3 = Digest::SHA1.hexdigest("#{salt}:qwerty") puts pass1==pass2 puts pass1==pass3 This works fine but i need to get the decrypted password how can i get it any help is

Im still following the authorization recipe from the book, now all works fine but im getting trouble in how handle the model authorization result, if the user and pass are correct, it goes to a welcome screen(admin.rhtml) but if wrong the model prints a message in an ugly exception like page "usr and pass not correct", i want to redirect the user to the login

hello, i am writing a simple user login system. when registering a user account, i have two field: password password_confirmation which are validated using validates_presence_of validates_confirmation_of and these are then used to generate a password hash which is stored in my database when i want to update the record (without changing the password and entering new values for password and

I created a simple registration form. One column doesn''t seem to be taking the input. I''ve yet to put in any validation or error checking. The column in the database is called ''level'' and is type ''int'' The controller method is fairly simple: def register c = User.new(params[:user]) c.save redirect_to :controller =>

Hello all, Thank you in advance for your help with this. I am trying to implement the user authentication method from Ruby Recipes which calls for the use of SHA 2. Here is the code for the password: def password=(pass) salt = [Array.new(6){rand(256).chr}.join].pack("m").chomp self.password_salt, self.password_hash = salt, Digest::SHA256.hexdigest(pass + salt) end I open

I have most of my books open as I''m trying to create this app. Still not sure how to make this work - hopefully some help / hints can get me further. First I used the "authorizing users" recipe from Rails Recipes. Though I did add some more generic type of registration fields (email, address, etc). I want the registration form on the main page(index) of the site. What I have

Aside from the replay attacks discussed, there are some other attack vectors on the cookie_session store. I appreciate (and admire!) Jeremy''s good humor on all of this: > Planting the seed here led to quick ripening and plenty of pesticide. > Thanks for the fish, all. > > jeremy Anyway, here''s what we came up with: 1. Brute Force SHA512 can be computed _very_ fast.

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)

using the Rails Recipes book, i went through the tutorial on setting up authentication on a site. the tutorial was great, but it raises a few questions. the fields in the database are password_hash, and password_salt. the tutorial creates another method for password that takes the value it was given and hashes it and adds the 6 character salt at the end. what if i want to perform validation

Given the use of random salts, you would have to generate (number of possible salts) rainbow tables. This drastically changes the CPU/storage tradeoffs. >

Hello all, I have 3 time series (tt) that I've fitted segmented regression models to, with 3 breakpoints that are common to all, using code below (requires segmented package). However I wish to specifiy a zero coefficient, a priori, for the last segment of the KW series (green) only. Is this possible to do with segmented? If not, could someone point in a direction? The final goal is to

How can I add a password in MySQL directly and match the one Rails create? I understand that it uses SHA1 and then HEX, right (require ''digest/sha1''). But when I try that in MySQL the resulted string isn''t the same. This is what I do in MySQL: SELECT SHA1(''password+salt'') The result is process with SELECT HEX(''result'') Btw, should
