    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.

    pwnat

    pwnat

    The only tool/technique to punch holes through firewalls

    ...It explores a technique for establishing connectivity without traditional port forwarding, DMZ configuration, or an external relay server. The project is written in C and focuses on low-level networking behavior. It is relevant for people studying NAT behavior, firewall traversal, peer-to-peer connectivity, and internet routing limitations. Because router behavior has changed over time, the technique should be treated as a historical and experimental networking project rather than a guaranteed modern solution. ...

    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.
