I agree RND is not truely random but you can improve it quite a bit if you use the INT to retrieve the number of time the 18.2 times a second interrupt has occured since the computer was powered up as a SEED. You can even obscure this number more by XOR'n it against the file size and use the resulting number as the seed. Use a database (.DAT file for ACCESS) stored on a USB memory stick to store the resulting random key used on a specific file. Remember to never use the same random key on more than one file. The more files the key is used on provides clues as to the key. (ex: Xor one file against the other). To enhanse the XOR even more, compress the file (remove repeating patterns) from the file before it is encrypted.
