Well... You can use PGPG/GNPGP for this or you can develop your own RSA encryption - if you understand/have the know how. A former programmer of mine who worked for a Security firm developed the base-line code which was originally written in C then transferred into Perl. He was greatful enough to provide us with the code (which is quite small) while working a few site before his departure. Seems to works like a charm and we've never had any issues with it (hacking, etc).

Isn't there any method (free, preferably) of ASSYMETRIC (Public key) cryptography I can use with PHP to store this data in a db?? Or is there any other good option instead of this?
