Attached is an AES256 encryption/decryption system written entirely in Tier1 and designed to handle files without altering the original. The program will create a new file from the encrypted/decrypted results with the word 'output-' added to the beginning of the filename. Instructions and descriptions of operations included in rem lines. Uses lookup tables and lean loops for simplicity and performance.

Thanks,

My interests of late involve patchwork using multiple encryption methods.
Specifically patchwork patterns to develop multiple dimensions of data in the same file, with most being decoy information.
The easy methods can be honey pots distracting from the real deal (proprietary, not government known/sponsored).

This should come in handy to distract the majority, so thanks again.

Indeed, you could certainly modify this or take parts of it to employ your own custom pattern shifts and methods, both for obscurity reasons and perhaps performance reasons.
