Tom,

I'm not aware of FoxCrypto.FLL, but the name Base64 means something to me. Isn't waht you're doing below the same as StrConv (cExpression, 13) and StrConv (cExpression, 14) ?

Regards,

Fernando

>>>I have a DBF that contains a user userid and password. I would like to encrypt the password column and be able to still use its value as normal. What is the best most straightforward way to do this without purchasing a third party product?
