hey this reminds me of my dusty project a while back
i took someones broken masking algorithm online because i needed it for my RSA and revised it to actually work
then developed my own demasking algorithm because the guy never made one. he asked someone to help develop one and i was going to reply back with my solution but the post was like 2 years old
its like a caesar cipher on drugs
it uses a key and its theoretically uncrackable without knowing the key. i think its called "one time padding" but idk
i wouldnt call it encryption exactly. its more like a way to parse the data so it can be interpreted correctly. text -> padded to fit bit length -> hex -> mask -> rsa both mask and key to mask
caesar cipher:
"aaaaa" -> "ddddd"
me:
"aaaaa" -> key: 5 -> "fLrXD"
i enjoy cryptography too op
