# Cryptography operations

- [HMAC](/hem-api/reference/api-reference/cryptography-operations/hmac.md): Those basic cryptography operations allow the calculation and verify HMAC messages.
- [ExDSA](/hem-api/reference/api-reference/cryptography-operations/exdsa.md): Those basic cryptography operations allow the calculation and verify ExDSA signatures. ECDSA and EdDSA are supported.
- [ECDH](/hem-api/reference/api-reference/cryptography-operations/ecdh.md): This basic cryptography operation allows the calculation of the ECDH between a trusted key or by an external public key.
- [Encryption](/hem-api/reference/api-reference/cryptography-operations/encryption.md)
- [Encryption/Decryption](/hem-api/reference/api-reference/cryptography-operations/encryption/encryption-decryption.md): These two endpoint implements the encryption and decryption of short data message using the AES scheme.
- [Wrap/Unwrap](/hem-api/reference/api-reference/cryptography-operations/encryption/wrap-unwrap.md): These two endpoint implements the NIST Key Wrapping scheme.
- [Post-Quantum Cryptography](/hem-api/reference/api-reference/cryptography-operations/post-quantum-cryptography.md): This section contains modern Post-Quantum Cryptography algorithms recently approved by the NIST.
- [ML-DSA](/hem-api/reference/api-reference/cryptography-operations/post-quantum-cryptography/ml-dsa.md): These two basic cryptography operations allow the calculation and verification of the ML-DSA signatures.
- [ML-KEM](/hem-api/reference/api-reference/cryptography-operations/post-quantum-cryptography/ml-kem.md): This section describes two endpoints functional for key-encapsulation PQC operations - ML-KEM, FIPS 203 compliant.
