Summary

Declaration

Definition

from sha512.h:111

int mbedtls_sha512_update(mbedtls_sha512_context *ctx, const unsigned char *input, size_t ilen);

Implemented in esp_sha512.c:312

Arguments

Argument

Description

ctx

The SHA-512 context. This must be initialized and have a hash operation started.

input
