OpenHarmony Universal KeyStore (HUKS) provides KeyStore (KS) capabilities for applications, including key management and key cryptography operations. HUKS also provides APIs for applications to import or generate keys.
### Basic Concepts
## Basic Concepts
- 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.
