Syntax
psa_status_t mbedtls_psa_sign_hash_start(
mbedtls_psa_sign_hash_interruptible_operation_t *operation,
const psa_key_attributes_t *attributes,
const uint8_t *key_buffer,
size_t key_buffer_size,
psa_algorithm_t alg,
const uint8_t *hash,
size_t hash_length);
Implemented in ![]()
psa_crypto.c:3842
Return value
#PSA_SUCCESS The operation started successfully - call \c psa_sign_hash_complete() with the same context to complete the operation #PSA_ERROR_INVALID_ARGUMENT An unsupported, incorrectly formatted or incorrect type of key was used. #PSA_ERROR_NOT_SUPPORTED Either no internal interruptible operations are currently supported, or the key type is currently unsupported. #PSA_ERROR_INSUFFICIENT_MEMORY There was insufficient memory to load the key representation.
