mbedtls_sha512_ret() function

This function calculates the SHA-512 or SHA-384 checksum of a buffer. The function allocates the context, performs the calculation, and frees the context. The SHA-512 result is calculated as output = SHA-512(input buffer).

Summary

Declaration

Definition

from sha512.h:245

int mbedtls_sha512_ret(const unsigned char *input, size_t ilen, unsigned char output[64], int is384);

Implemented in sha512.c:427

Arguments

Argument

Description

input

The buffer holding the input data. This must be a readable buffer of length \p ilen Bytes.

ilen

The length of the input data in Bytes.

output

The SHA-384 or SHA-512 checksum result. This must be a writable buffer of length \c 64 Bytes.

is384

Determines which function to use. This must be either \c 0 for SHA-512, or \c 1 for SHA-384.

Return value

\c 0 on success. A negative error code on failure.

Notes

When \c MBEDTLS_SHA512_NO_SHA384 is defined, \p is384 must be \c 0, or the function will return #MBEDTLS_ERR_SHA512_BAD_INPUT_DATA.
