3.3.2.2 Crypto_Hash_Sha_Update
crypto_Hash_Status_E Crypto_Hash_Sha_Update(
st_Crypto_Sha_Hash_Ctx *ptr_shaCtx_st,
uint8_t *ptr_data,
uint32_t dataLen
);Description
This API performs hash calculation for different variants of SHA-1, SHA-2, and SHA-3(Excluding SHAKE) algorithms in multi-steps. Initialize context by calling Crypto_Hash_Sha_Init function before calling this API and after this API call Crypto_Hash_Sha_Final to get hash/digest.
