Read Write RandomEncryption - OOP
Posted: Fri Oct 23, 2020 3:43 am
Hello everyone,
A small library based on NicTheQuick's original code found in the code archive.
The main purpose of the library is to make the data obscure in a file. It should not be used when security is needed.
I'm releasing it in hope it might be useful to some one.
Best regards
StarBootics
