MD5 – insert an encrypted string or password to the MySQL database with HTML form and PHP

Editor’s note: In a login system, there are user names and passwords stored in the MySQL database. The passwords are normally stored as strings inside the database. To have a more security way to store the passwords in the database, it is better to store an encrypted version of the password, therefore only the password creator knows what the password is.

MD5 is the encryption technology I like to use because it is very easy to implement and it encrypts a string into a 32-character strings, for reference what MD5 really is, please check Wikipedia-MD5.
