 - HUKS provides key management functions, including encryption and decryption, signing and signature verification, key agreement and derivation, and Hash-based Message Authentication Code (HMAC) calculation.
 - HUKS supports the following algorithms: AES and RSA in encryption and decryption, RSA, ECC, DSA, and ED25519 in signing and signature verification, PBKDF2 in key derivation, and DH, ECDH, and X25519 in key agreement.
 - HUKS uses the OpenSSL and Mbed TLS algorithm libraries.
