I am using a wordpress site. I just want to know , How to get a plain text from encrypted password(stored in wordpress database). I used the $wp_hasher->CheckPassword($plain_password, $password_hashed) to check the password is correct or not. But this time i would like to know how to get plain text.
You will not be able to retrieve a plain text password from wordpress.
Wordpress use a 1 way encryption to store the passwords using a variation of md5. There is no way to reverse this.
See this article for more info http://wordpress.org/support/topic/how-is-the-user-password-encrypted-wp_hash_password
This is one of the proposed solutions found in the article Jacob mentioned, and it worked great as a manual way to change the password without having to use the email reset.
- In the DB table
wp_users, add a key, like abc123 to theuser_activationcolumn. - Visit yoursite.com/wp-login.php?action=rp&key=abc123&login=yourusername
- You will be prompted to enter a new password.
