fn new128xof #
fn new128xof(output_len int) !&Digest
new128_xof initializes the digest structure for a sha3 128 bit extended output function
fn new224 #
fn new224() !&Digest
new224 initializes the digest structure for a sha3 224 bit hash
fn new256 #
fn new256() !&Digest
new256 initializes the digest structure for a sha3 256 bit hash
fn new256xof #
fn new256xof(output_len int) !&Digest
new256_xof initializes the digest structure for a sha3 256 bit extended output function
fn new384 #
fn new384() !&Digest
new384 initializes the digest structure for a sha3 384 bit hash
fn new512 #
fn new512() !&Digest
new512 initializes the digest structure for a sha3 512 bit hash
fn new_digest #
fn new_digest(absorption_rate int, hash_size int) !&Digest
new_digest creates an initialized digest structure based on the hash size and whether or not you specify a MAC key.
absorption_rate is the number of bytes to be absorbed into the sponge per permutation.
hash_size - the number if bytes in the generated hash. Legal values are 224, 256, 384, and 512.
fn new_xof_digest #
fn new_xof_digest(absorption_rate int, hash_size int) !&Digest
new_xof_digest creates an initialized digest structure based on the absorption rate and how many bytes of output you need
absorption_rate is the number of bytes to be absorbed into the sponge per permutation. Legal values are xof_rate_128 and xof_rate_256.
hash_size - the number if bytes in the generated hash. Legal values are positive integers.
