NAME
UUID::URandom - UUIDs based on /dev/urandom or the Windows Crypto API
VERSION
version 0.001
SYNOPSIS
use UUID::URandom qw/create_uuid/;
my $uuid = create_uuid();
DESCRIPTION
This module provides a portable, secure generator of RFC-4122
<
https://tools.ietf.org/html/rfc4122> version 4 (random) UUIDs. It is a
thin wrapper around Crypt::URandom to set the UUID version and variant
bits required by the RFC.
USAGE
No functions are exported by default.
FUNCTIONS
create_uuid
my $uuid = create_uuid();
# "\x95\x5a\xe4\x96\x8b\xb2\x45\x0b\x9c\x7e\x99\xf5\x01\xdf\x90\xfe"
This returns a new UUID as a 16 byte 'binary' string.
create_uuid_hex
my $uuid = create_uuid_hex();
# "955ae4968bb2450b9c7e99f501df90fe"
This returns a new UUID as a 32-byte hexadecimal string.
create_uuid_string
my $uuid = create_uuid_string();
# "955ae496-8bb2-450b-9c7e-99f501df90fe"
This returns a new UUID in the 36-byte RFC-4122 canonical string
representation. (N.B. The canonical representation is lower-case.)
FORK AND THREAD SAFETY
The underlying Crypt::URandom is believed to be fork and thread safe.
SEE ALSO
There are a number of other modules that provide version 4 UUIDs. Many
rely on insecure or non-crypto-strength random number generators.
