Encrypted data

Hi,
How can I save encryped data in SQL2000? Also, how can I retrieve it?xp_crypt (http://www.activecrypt.com/xp_crypt_364d.zip)|||I have written my own encryption algo in all our in-house applications
and it is running great guns...
I handled both encryption and decrytion at app level,i.e both encrypt()
and decrypt() are defined in applications
just try writing ur own encrypt function or use std algo like
blowfish etc...
