Java Encryption and Decryption

[devtamil]

Hai,

I am new java developer. Now i am doing one struts application.

In my application, at the User registration time, i need to Encrypt the password field and then i like to store into the database.


After that the same user will be logging, at the moment the database password will decrypt and it will be compare to the User entering password.


If both password's are equal, then only the User will allow the logging.


can anybody know or have any sample code for Encrypt and Decrypt.

If yes, kindly post me, my mail id is tamilvanan@veradistech.com.

I am expecting anyone's reply.


Thanks

use a DES or 3DES related classes, after you define the encryption key they will encrypt the data for you. Many people uses MD5 hash function as a tool for encryption. DON'T do things like that! Encryptions are different than Integrity checks, MD5 is a hash function, means it is not an encryption.
