VERSION

SYNOPSIS
use Crypt::SysRandom 'random_bytes';
my $random = random_bytes(16);DESCRIPTION
This module uses whatever interface is available to procure cryptographically random data from the system. All functions are optionally exported.
FUNCTIONS
random_bytes($count)
This will fetch a string of $count random bytes containing cryptographically secure random data.
random_hex($count)
This will fetch a string of $count random bytes containing cryptographically secure random data and hex encode it (so the result will be twice as many bytes).
random_base64($count)
This will fetch a string of $count random bytes containing cryptographically secure random data and base64 encode it (so the result will be about 33% larger).
random_base64url($count)
This will fetch a string of $count random bytes containing cryptographically secure random data and base64url encode it (so the result will be about 33% larger).
random_uuid()
This will generate a cryptographically random UUIDv4.
