security/codecrypt 1.8nb1 NetBSD

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

Stream ciphers used: ChaCha20, XSynd stream cipher, RC4 (for initial simplicity of implementation)

CRHFs used:

• Cubehash variants were selected for implementation ease, really clean design, quite good speed and flexibility of parameter choices. KeyID's are CUBE256 hashes of serialized public key.
• 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

Encryption: MDPC McEliece on quasi-cyclic matrices - decoding is (slightly) vulnerable to timing attacks.
