Login Encrypt is a security plugin. It uses a complex combination of DES and RSA.
It was first developed by ELSERVER for securing login in the hosting control panel, and then released as a WordPress plugin.
The way it works (fast explanation):
* The encripted password and the encrypted DES unique key are sended to the server.
* A hook when login in checks if a encrypted DES unique key is received. If does, decrypts it using the secure RSA private key.
* Then, decrypts the password using the DES unique key.
