Cipherinit
WebThis includes cryptographic functions that span various cryptographic needs: message digests, symmetric ciphers, message authentication codes (MAC), authenticated encryption, asymmetric operations (encryption/decryption or signing/verifying), key derivation, and random data generation. These functions make up the TEE Cryptographic Operations API.
