NAME

sha3_224_init, sha3_256_init, sha3_384_init, sha3_512_init, sha3_update, sha3_final - compute the SHA3 of a given block of data

SYNOPSIS

#include <limb/sha3.h>

void sha3_224_init(void *ctx);
void sha3_256_init(void *ctx);
void sha3_384_init(void *ctx);
void sha3_512_init(void *ctx);
void sha3_update(const void *msg, size_t size, void *ctx);
void sha3_final(void * restrict md, void *ctx);

DESCRIPTION

The sha3_224_init() function initializes the given sha3 context ctx to calculate a digest of 224 bits.

The sha3_256_init(), sha3_384_init() and sha3_512_init() functions are similar, but initializing the conext for a SHA3 of 256, 384 and 512 bits respectively.

The sha3_update() function feeds the specified chunk of data pointed by msg of length size (in bytes) to be hashed into the given ctx. You can call this function repeatedly as many times as needed.

The sha3_final() function stores the calculated hash from ctx in binary form into md, which must be able to store as many bytes as needed: bits / 8, where bits corresponds to the sha3_*_init() function called.
