The decript code will have to match the encript code. I don't think you can encript something with one algorithm and decript it with another and end up with the original object.

There have been other posts on this topic. Use search to find them.

actually this i have one md5 tech to enc the value

but we cant dec md5 value . as per my know.

so how i can?

Indeed md5 is almost not reversible. It is very hard to restore original bytes you have md5 from.

Better use javax.crypto facility

Hi,

There are many links that give you java code examples for both encrypting and decrypting. I would add some more links to the one already provided.
