Deprecated type for mcuxClSession protected status codes.
Deprecated type for RSA protected status codes.
Deprecated type for error codes used by code-flow protected PKC component functions.
Deprecated type for error codes used by code-flow protected mcuxClMemory component functions.
Deprecated type for error codes used by code-flow protected Math component functions.
Deprecated type for Key component error codes, returned by functions with code-flow protection.

Verifies an ECDSA signature of a given message.
Generates an ECDSA signature of a given message.
Performs a Diffie-Hellman key exchange with an internal ECC private key and an external ECC public key.
Before execution, ELS will wait until mcuxClEls_HwState_t.drbgentlvl == MCUXCLELS_STATUS_DRBGENTLVL_HIGH. This can lead to a delay if the DRBG is in a state with less security strength at the time of the call.
Call #mcuxClEls_WaitForOperation to complete the operation. The public key will be stored in the standard ANSI X9.62 byte order (big-endian).
