Magic Encoding is a method of encoding files only using the first 17 bytes. The purpose of the encoding is to encode the file using bytes that represent special/magic characters to confuse the file readers trying to open it. Any file encoded with this method will be seen as a "binary file" and will most likely cause errors to code and programs that try to read it as text.
The data encoding is very simple, for every byte in the original file, a div and mod of 16 is stored in the new file, then to decode the new file the very simple byte = div*16 + mod formula is applied. The encoding also stores the filename making the final form encoded_name + byte 17 + encoded_data. Due to this, the encoded file will be double in size.
This was a small project of mine, however if anyone wants to take it seriously here are a few ideas to try:
• encoding depth: encode the file multiple times(however it can be bruteforced by checking for byte values above 17 and it will keep increasing the file size, probably useful for small text files)
• file compression: compress the file without using byte values above 31(this may not be possible due to loss of information, but you're welcome to try it)
• parallel processing: utilize parallel programming to encode/decode files to increase speed.
• non-python implementation: rewrite the project in a much faster programming language such as c/c++.
• encoding alphabet: map the best 16 bytes out of the 31 available to the range of 0-16 to make the encoded text even more confusing(example: tab, newline, del, backspace).
