Summary

Declaration

from sha3.h:153

int mbedtls_sha3(mbedtls_sha3_id id, const uint8_t *input, size_t ilen, uint8_t *output, size_t olen);

Arguments

Argument

Description

The id of the SHA-3 family.

input

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

ilen

The length of the input data in Bytes.

output

The SHA-3 checksum result. This must be a writable buffer of length \c olen bytes.

olen

Defines the length of output buffer (in bytes). For SHA-3 224, SHA-3 256, SHA-3 384 and SHA-3 512 \c olen must equal to 28, 32, 48 and 64, respectively.

Return value

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