# Post-Quantum Cryptography (PQC)

In addition to traditional cryptography algorithms, emCA supports NIST -PQC algorithms, to ensure cryptographic security against potential quantum computing threats:

* **CRYSTALS-Dilithium** (NIST Round 3 signature scheme)
  * Level 2, Level 3, Level 5 parameter sets
* **Falcon** (NIST Round 3 signature scheme)
  * Falcon-512, Falcon-1024
* **SPHINCS+** (Hash-based signature scheme per NIST)
  * Variants based on different hashing schemes (e.g., SHA2-based, Haraka-based)
