mbedtls_md_hmac_update() function

This function feeds an input buffer into an ongoing HMAC computation. Call mbedtls_md_hmac_starts() or mbedtls_md_hmac_reset() before calling this function. You may call this function multiple times to pass the input piecewise. Afterwards, call mbedtls_md_hmac_finish().

Syntax

int mbedtls_md_hmac_update( mbedtls_md_context_t *ctx,     const unsigned char *input,     size_t ilen );
Implemented in md.c:366

Arguments

ctx

The message digest context containing an embedded HMAC context.

input

The buffer holding the input data.

ilen

The length of the input data.

Return value

\c 0 on success. #MBEDTLS_ERR_MD_BAD_INPUT_DATA on parameter-verification failure.
