The finalized standards include three post-quantum cryptographic algorithms. 

One – ML-KEM [PDF] (based on CRYSTALS-Kyber) – is intended for general encryption, which protects data as it moves across public networks. The other two – ML-DSA [PDF] (originally known as CRYSTALS-Dilithium) and SLH-DSA [PDF] (initially submitted as Sphincs+) – secure digital signatures, which are used to authenticate online identity.

A fourth algorithm – FN-DSA [PDF] (originally called FALCON) – is slated for finalization later this year and is also designed for digital signatures.
