NAME
Math::Base85 - Perl extension for base 85 numbers, as referenced by RFC 1924SYNOPSIS
use Math::Base85; $bigint = from_base85($number); $b85str = to_base85($bigint);
DESCRIPTION
RFC 1924 describes a compact, fixed-size representation of IPv6 addresses which uses a base 85 number system. This module handles some of the uglier details of it.The base 85 numbers (from 0 to 84) are as follows:
0..9 A..Z a..z ! # $ % & ( ) * + - ; < = > ? @ ^ _ ` { | } ~
At the moment, there's not much in this module. But it should be sufficient for the purposes of RFC 1924.
This module has a variable called $Math::Base85::base85_digits, which is a string containing the digits of the base 85 alphabet from lowest (0) to highest (~), in that order.
Additionally, the following two functions are defined for general use. (They will be exported upon request.)
from_base85
Parameters
A string composed of valid base 85 digits.Returns
A "Math::BigInt" object representing the number.to_base85
Parameters
A "Math::BigInt" object.Returns
A string of base 85 digits representing the number.AUTHOR
