crypto.rand #

fn bytes #

fn bytes(bytes_needed int) ![]u8

bytes returns an array of bytes_needed random bytes.

Note: this call can block your program for a long period of time, if your system does not have access to enough entropy. See also rand.bytes(), if you do not need really random bytes, but instead pseudo random ones, from a pseudo random generator that can be seeded, and that is usually faster.

fn int_u64 #

fn int_u64(max u64) !u64

int_u64 returns a random unsigned 64-bit integer u64 read from a real OS source of entropy.

fn read #

fn read(bytes_needed int) ![]u8

read returns an array of bytes_needed random bytes read from the OS.

fn (ReadError) msg #

fn (err ReadError) msg() string
