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 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.
