Sarah,

One easy method of encrypting text is to XOR each character with a key character. When you XOR the result with the key again it'll give back the plaintext:

lcPlainText = "A"
lcKey = "#"
lcEncrypt = chr( bitxor( asc( lcPlainText ), asc( lcKey ) ) )
? lcEncrypt
lcDecrypt = chr( bitxor( asc( lcEncrypt ), asc( lcKey ) ) )
? lcDecrypt

Just step through the text one character at a time. To make it a little harder you could also change the positions of some of the encrypted text, like reverse it or transpose every other character.

If the surname, when encrypted, doesn't match the code then reports and exports are disabled. The users surname is printed on all reports so if they pass the software around they'll have to have another person's name on all their stuff which will hopefully aggravate them into buying a legit copy.
