Constants #

const size160 = 20

size160 is the size, in bytes, of a Blake2b 160 checksum.

const size256 = 32

size256 is the size, in bytes, of a Blake2b 256 checksum.

const size384 = 48

size384 is the size, in bytes, of a Blake2b 384 checksum.

const size512 = 64

size512 is the size, in bytes, of a Blake2b 512 checksum.

const block_size = 128

block_size is the block size, in bytes, of the Blake2b hash functions.

fn new160 #

fn new160() !&Digest

new160 initializes the digest structure for a Blake2b 160 bit hash

fn new256 #

fn new256() !&Digest

new256 initializes the digest structure for a Blake2b 256 bit hash

fn new384 #

fn new384() !&Digest

new384 initializes the digest structure for a Blake2b 384 bit hash

fn new512 #

fn new512() !&Digest

new512 initializes the digest structure for a Blake2b 512 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 64.

key - key used for generating a prefix MAC. A zero length key is used for just generating a hash. A key of 1 to 64 bytes can be used for generating a prefix MAC.
