    HPN-SSH is a series of performance patches for OpenSSH. By addressing network limitations and CPU limitations significant throughput performance can be realized. Gains of close to two orders of magnitude are possible on long fat network paths. The official git repo is now available at http://github.com/rapier1/openssh-portable. The Sourceforge repository should not be seen as the canonical repository for HPN-SSH. We will update it as we can but users should look to github to generate...

    Hash Latch
    The hash latch generates keys in a manner similar to how some cryptocurrencies are mined. It takes a string and brute-forces a prefix for it so that the hash of the string with the prefix has a certain number of leading zeroes. But that alone would've been too easy to hack. To prevent an attacker from forging the keys by generating a new prefix: the hash latch doesn't output the keys in the plaintext. Instead, it encrypts the key and outputs the ciphertext. That means that instead of...

    strobe

    STROBE cryptographic protocol framework

    Note: this is alpha-quality software, and isn't ready for production use. STROBE is a lightweight framework for cryptographic protocols. It supports encryption/decryption, hashing, pseudorandom generation and message authentication. It integrates these components in an innovative way that makes secure protocol design relatively simple. With the included elliptic curve code, STROBE additionally supports asymmetric key exchange and digital signature creation and verification.

    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.
