mbedtls_md_hmac_finish() function

This function finishes the HMAC operation, and writes the result to the output buffer. Call this function after mbedtls_md_hmac_starts() and mbedtls_md_hmac_update() to get the HMAC value. Afterwards you may either call mbedtls_md_free() to clear the context, or call mbedtls_md_hmac_reset() to reuse the context with the same HMAC key.

Syntax

int mbedtls_md_hmac_finish( mbedtls_md_context_t *ctx,     unsigned char *output);
Implemented in md.c:374

Arguments

ctx

The message digest context containing an embedded HMAC context.

output

The generic HMAC checksum result.

Return value

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