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.
