Package frodo provides the key encapsulation mechanism FrodoKEM.

Package hybrid defines several hybrid classical/quantum KEMs for use in TLS.

Package kyber implements the CRYSTALS-Kyber.CCAKEM IND-CCA2 secure key encapsulation mechanism (KEM) as submitted to round 3 of the NIST PQC competition and described in https://pq-crystals.org/kyber/data/kyber-specification-round3.pdf The related public key encryption scheme CRYSTALS-Kyber.CPAPKE can be found in the package github.com/cloudflare/circl/pke/kyber.

Package mlkem implements IND-CCA2 secure ML-KEM key encapsulation mechanism (KEM) as defined in FIPS 203.

Package schemes contains a register of KEM schemes.

Package sike is deprecated, it contains the SIKE key encapsulation mechanism.
