Constants #

const size128 = 16

size128 is the size, in bytes, of a Blake2s 128 checksum.

const size160 = 20

size160 is the size, in bytes, of a Blake2s 160 checksum.

const size224 = 28

size224 is the size, in bytes, of a Blake2s 224 checksum.

const size256 = 32

size256 is the size, in bytes, of a Blake2s 256 checksum.

const block_size = 64

block_size is the block size, in bytes, of the Blake2s hash functions.

fn new128 #

fn new128() !&Digest

new126 initializes the digest structure for a Blake2s 128 bit hash

fn new160 #

fn new160() !&Digest

new160 initializes the digest structure for a Blake2s 160 bit hash

fn new224 #

fn new224() !&Digest

new224 initializes the digest structure for a Blake2s 224 bit hash

fn new256 #

fn new256() !&Digest

new256 initializes the digest structure for a Blake2s 256 bit hash

fn new_digest #

fn new_digest(hash_size u8, key []u8) !&Digest

new_digest creates an initialized digest structure based on the hash size and whether or not you specify a MAC key.

hash_size - the number if bytes in the generated hash. Legal values are between 1 and 32.

key - key used for generating a prefix MAC. A zero length key is used for just generating a hash. A key of 1 to 32 bytes can be used for generating a prefix MAC.
