[Tony2005]

what i've been messing with encryption wise just just putting the ascii code through a simple forumla (just untill i get the program running correctly) but i would like to know what other methods are available? im currently using VB 6.0

Probably the simplest method would be to XOR (Exclusive OR) each byte in the file. If you've never heard of XOR, basically if you take a number and XOR once you'll get a second number, XOR the second number with the same number you used at first and you get the number you started with:

109 XOR 23 = 122
122 XOR 23 = 109

This is handy because you can use the same routine for encryption and decryption.

i'll give it a go - i'll just use it with the ascci for now
