Codecrypt: The post-quantum cryptography tool.
by coderman 10 Feb '21

10 Feb '21

https://gitea.blesmrt.net/exa/codecrypt Codecrypt The post-quantum cryptography tool. About This is a GnuPG-like unix program for encryption and signing that uses only quantum-computer-resistant algorithms: - McEliece cryptosystem (compact QC-MDPC variant) for encryption - Hash-based Merkle tree algorithm (FMTSeq variant) for digital signatures Codecrypt is free software. The code is licensed under terms of LGPL3 in a good hope that it will make combinations with other tools easier. Why this? Go read http://pqcrypto.org/ Links - infopage: http://e-x-a.org/codecrypt/ - package downloads: http://e-x-a.org/codecrypt/files/ Distro packages - Gentoo packages: https://packages.gentoo.org/packages/app-crypt/codecrypt with current ebuild usually available at http://e-x-a.org/codecrypt/files - Debian packages: apt-get install codecrypt - Arch linux: see https://aur.archlinux.org/packages/codecrypt/ - Windows port is maintained separately here: https://github.com/mike805/codecrypt-win32 Language wrappers: - Python bindings: https://github.com/mike805/codecrypt-python/ Documentation There is a complete, UNIXy manual page supplied with the package. You can view it online here: http://e-x-a.org/codecrypt/ccr.1.html Used cryptography overview To achieve the stated goal, codecrypt uses a lot of (traditional, but "quantum-secure") cryptographic primitives. Choices of primitives were based on easy auditability of design, simplicity and provided security. The git repo of codecrypt contains doc/papers with an unsorted heap of academic papers and slides about relevant topics. Stream ciphers used: - ChaCha20, the recommended choice from djb - XSynd stream cipher as an interesting and nontraditional candidate also based on assumptions from coding theory; used NUMS (it requires lot of NUMS) are explained in doc/nums directory in the repo. - Arcfour for initial simplicity of implementation. After recent statistical attacks I cannot recommend using any RC4 variant anymore, but provided padding and the "offline-only" usage of codecrypt keeps the usage mostly secure. CRHFs used: - Cubehash variants were selected for implementation ease, really clean design, quite good speed and flexibility of parameter choices. This is also the only hash possibility when Crypto++ library is not linked to codecrypt. KeyIDs are CUBE256 hashes of corresponding serialized public keys. - ripemd128 for small hashes - tiger192 is used as an alternative for Cubehash for 192bit hashes - There's always a variant with SHA-256, SHA-384 or SHA-512. Signature algorithms: - FMTSeq with many possibilities and combinations of aforementioned CRHFs - SPHINCS256 support is scheduled for next release Encryption algorithms: - MDPC McEliece on quasi-cyclic matrices. The implementation uses some tricks to speedup the (pretty slow) cyclic matrix multiplication (most notably libfftm3 in this version). For padding using the Fujisaki-Okamoto scheme, the cipher requires a stream cipher and a CRHF, used ciphers and CRHFs are specified in the algorithm name -- e.g. MCEQCMDPC128FO-CUBE256-CHACHA20 means that the parameters are tuned to provide 128bit security, uses CUBE256 hash, and ChaCha20 stream cipher. - Quasi-dyadic McEliece was included in codecrypt as an original algorithm, but is now broken and prints a warning message on any usage. Caveats: Cryptography is not intended for "online" use, because some algorithms (especially the MDPC decoding) are (slightly) vulnerable to timing attacks. Quick How-To Everything is meant to work mostly like GnuPG, but with some good simplicity margin.

Stick around, there have been onslaughts of repugnant creeps and geeks and misfits since cpunks beginning. They dump their shit then move on, a few come back with even stinkier droppings. Set your filter to trash, spamblock, kill the motherfuckers, well, not the last, that is the kind of narcissistic compliment they most beg for. Courtesy enrages and disempowers them, so keep that up.
