Password Encryption is a way to keep your account safe. In this case, we'll use MD5. MD5(Message Digest Algorithm 5) is an one way password encryption, so you can't get the last word you've entered before. MD 5 is created by Ron Rivest, the newest edition is MD6. the MD5 programs will encrypt your word into 32 characters which combined in numbers, special characters, and letters, its unable to decrypt(as I said it's an one way password encryption program).
