    Cipherbox

    Cipherbox

    Cipherbox is a vault that utilizes six encryption algorithms.

    This project is deprecated. Please refer to https://sourceforge.net/projects/midbar/ or https://sourceforge.net/projects/midbar-firebase-edition/ Cipherbox was my attempt to build a multi-user Midbar. Cipherbox is what I consider to be a cryptographic swiss knife. It utilizes six encryption algorithms, and it's also a vault that's locked with four RFID cards, your username, and password.

    obfusc

    toolchain for obfuscated compilation

    This is a C compiler, assembler, linker and virtual machine for computing based on encrypted working and obfuscated compilation and execution. The idea is that the platform machine `works encrypted' for the user and unencrypted for the operator, running a machine code instruction set in user mode that is provably safe against computational attacks, for code that is generated by a compiler that has introduced random variations into the code at each recompilation so that the attacker has no statistical leverage from human programming biases.
