Post-quantum cryptography is a subset of cryptography designed to be secure against quantum computers. Some currently used cryptography is quantum-safe, meaning it is secure even if adversaries can use quantum computers. However, new post-quantum algorithms (especially Latticed-based cryptography) are designed to be quantum-safe or quantum-proof.
Most symmetric encryption schemes are considered quantum-safe if they use sufficiently large key sizes. The same is said for most hash functions. However, it is essential to note that no cryptography can ever be guaranteed to be secure forever. Cryptography is constantly being tested and analyzed to make reliable assumptions about its security.
Code Siren implements the post-quantum algorithms submitted and accepted by the National Institute of Standards and Technology (NIST) standardization process. We believe they are promising long-term candidates for post-quantum cryptography standards.
Polynom uses the very latest and strongest PQC encryption recommended by NIST and the US NSA's Commercial National Security Algorithm (CNSA) Suite.

Eventually, the CNSA1.0 algorithms will be phased out of Polynom.
