* Display the unencrypted and encrypted passwords.

* Complete hashed password in hexadecimal format */ * The bytes array has bytes in decimal form. * Add plain-text password bytes to digest using MD5 update() method. MessageDigest m = MessageDigest.getInstance('MD5') This algorithm is defined under curity package in Java programming. It is a cryptographic hash function that generates a 128-bits hash value. The MD5 (Message Digest) is a very popular hashing algorithm. Java programming supports several hashing techniques in order to encrypt a password. The encrypted hash value is generated using certain algorithms on the plain text password provided by the user. But the hashing is one of the most popular encryption techniques. There are many methods that can be used to encrypt the password. Using various encryption techniques, the plain text password is stored in an encrypted form in the database. To ensure the security of the user's password, it is encrypted using different encryption techniques. Hackers may break the system and steal the passwords from the database. Storing the plain text as it is into the database is not secure at all.

When a user sets his/her password, it stores in the database as a plain text. Because anyone with valid credentials can enter into the system and access the information. But while creating a password, one must be very careful. A username can be anything like an email-id or just a combination of characters.
