>I am using vfpencryption.fll in encrypt a user's password and then I am using strconv(password,15) to convert the results so it will store in a database easier. I have run into an issue trying to test if the password is encrypted so I don't try and encrypt it twice. Is there a way to test if a string has been converted?

The suggestions you already got look good to me. One question though:

Why STRCONV(15) (HexBinary) instead of STRCONV(13) (BASE64) which tends to produce shorter strings and also is pure text, and goes well in XML strings?
