#include <crypto/nrf_cc310_bl/include/nrf_cc310_bl_ecdsa_verify_secp256r1.h>

Function for executing an ECDSA verify operation using secp256r1 with hash input in integrated form.

Note

This will run initialization of ECDSA context and run ECDSA verify in a single step.

Parameters

[in,out]	p_context	Pointer to the structure holding context information for the ECDSA verify operation.
[in]	p_public_key	Pointer to the structure holding the public key for the ECDSA verify operation.
[in]	p_signature	Pointer to the structure holding the signature to use for the ECDSA verify operation.
[in]	p_hash	Pointer to the hash to use in the ECDSA verify operation.
[in]	hash_len	Length of the hash to verify.

Return values

CRYS_OK	Signature was successfully verified.
CRYS_ECDSA_VERIFY_INVALID_USER_CONTEXT_PTR_ERROR	p_context was NULL.
CRYS_ECDSA_VERIFY_USER_CONTEXT_VALIDATION_TAG_ERROR	p_context was not initialized.
CRYS_ECDSA_VERIFY_SIGNER_PUBL_KEY_VALIDATION_TAG_ERROR	p_public_key was NULL.
CRYS_ECDSA_VERIFY_INVALID_SIGNATURE_IN_PTR_ERROR	p_signature was NULL.
CRYS_ECDSA_VERIFY_INVALID_MESSAGE_DATA_IN_PTR_ERROR	p_hash was NULL.
CRYS_ECDSA_VERIFY_INVALID_MESSAGE_DATA_IN_SIZE_ERROR	hash_len was invalid.
CRYS_ECDSA_VERIFY_INCONSISTENT_VERIFY_ERROR	Signature verification failed.
