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.
