Need Fast and Simple Text Encryption

[ayyappan Bas]

Hi, I need to implement text encryption in my program.
Though ive read about encryption before in passing I dont
know much about the different types so I was hoping someone
could help me pick one.

The Java API for encryption/decryption is called "JCE". The http://faq.javaranch.com/java/SecurityFaq has a number of links regarding that, including articles that have sample code for using the DES and AES ciphers in Java.

I'll move this to a more appropriate forum, since it has nothing to do with JSP. Please CarefullyChooseOneForum.

Don't use DES for anything new. its OK to use it for legacy compatibility.

If you don't know, just use AES with 128 bit keys

You can also refer to this link for example code:
http://www.idevelopment.info/data/Programming/java/security/java_cryptography_extension/StringEncrypter.java
It shows encryption-decryption for 3 algorithms: Blowfish, DES, Triple DES

Don't go to that link! The code there contains atrocious and immoral exception handling, and just serves to poison the thinking of java beginners.

Listen to Greg. That code is sinful. Especially the encrypt and decrypt routines. Never do it that way.
