Re: Change password algorithm?
10 July 2011 at 9:01pm
Hi there. I've got exactly the same problem - 2000 users from an old site, and a new 'silverstriped' version ready to go - i just can't get the users transferred...
did anyone get any documentation written up on this one?

Re: Change password algorithm?

I solved it the following way:
1) Create Encryptor class like e.g.
class ForumPasswordEncryptor extends PasswordEncryptor{
public function encrypt($password, $salt = null, $member = null){
return md5(md5($password).$salt);
}
public function salt($password, $member = null){
return '';
}
}2) Register you class with a unique string in your config.php
PasswordEncryptor::register('md5_forum', 'ForumPasswordEncryptor');
3) Now it's tricky
I would expect to tell a Member (or Security or Group) to use my newly created encryptor for encryption somehow like this:// DID NOT WORK
Security::set_password_encryption_algorithm('md5_forum');
$salt = 'Put your salt in here';
$m = new Member();
$m->setField('Email', $user['Email']);
$m->setField('PasswordEncryption', 'md5_forum');However, this did not work. The passwords in database were different from my test results, so I used instead the following code:
// DID WORK
// Example 1
Security::set_password_encryption_algorithm('none');
$salt = 'Put your salt in here.';
$m = new Member();
$m->setField('Email', $user['Email']);
$m->setField('Password', md5($user['Password'].$salt));
$m->setField('PasswordEncryption', 'none');This way the password string provided by setField('Password', md5...) was saved exactly the same into database. After this I changed the column holding the encription string in database manually to 'md5_forum' and now I could login into silverstripe with my old password from the other (old) forum.
This have been the steps I remember...hope I didn't forget anything important. Would be nice to hear about your solution. I'd like to know why it didn't work with setting password encryption algorith to 'md5_forum' in my code.
