Hello,

I need to encrypt a short string (less than 80 characters probably) to be stored in a database. However, should the database be compromised, I need the encrypted data to decrypt with a different key so that the data in the database is worthless without the decryption key.

I had a look at "Perl modules for light to moderate encryption" - http://www3.marketrends.net/encrypt/ - but they all used symmetric key encryption (or at least, that is what I think it is called when you use the same key for both operations).

Do I need some form of public/private key encryption here? If so, which perl module would be advised for my needs?

Thanks,

fx
