NAME

Net::Address::IP::Cipher - IPv6 / IPv4 address encryption to a valid address, for pseudo anonymization.

VERSION

Version 0.6

SYNOPSIS

Net::Address::IP::Cipher encrypts and decrypts IPv6 and IPv4 addresses to another valid IPv6/v4 address, using a secret key, in a way that's impossible to guess the original IP without the key.

use Net::Address::IP::Cipher;

my $ipcipher = Net::Address::IP::Cipher->new(
    password => 'super secret'
);
my $enc = $ipcipher->enc('::1');
print $enc; # 3a3e:7137:6e36:5ecd:4d31:e516:cf47:ec1b

It's intended use is to pseudo-anonymize IPs from logs, packet captures, and other analysis. By this way you benefit of having still valid IP addresses and be able to group streams of several messagess, but without revealing the source.

This module implements in native perl language the "ipcipher" specification from: https://github.com/PowerDNS/ipcipher

PREREQUISITES

This module requires Net::IP for v6/v4 handling and CryptX for all crypto stuff (Crypt::KeyDerivation, Crypt::Cipher::AES).

METHODS

new

Creates a new Net::Address::IP::Cipher object. You must indicate the secret key for encryption/decryption:

my $ipcipher = Net::Address::IP::Cipher->new(password => 'super secret');

The key should be declared in either one of two formats:

password => 'super secret'

for any string used as a password, or

barekey => 'bb8dcd7be9a6f43b3304c640d7d7103c'

for an hexadecimal representation of a 128-bit key.

If you provide both, just the 'password' format will be used.

enc

Receive an IPv6 or IPv4 string address, in any valid format for Net::IP, and returns the encrypted version as string.

my $enc = $ipcipher->enc('::1');
print $enc;  # b733:fb7:c957:82fc:3d67:e7c3:a667:28da

dec

Receive and IPv6 or IPv4 string address in its encrypted version, and returns the decrypted IP string.

my $dec = $ipcipher->dec('b733:fb7:c957:82fc:3d67:e7c3:a667:28da');
print $dec;  # ::1
