Net-Address-IP-Cipher 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). INSTALLATION To install this module, run the following commands: perl Makefile.PL make make test make install SUPPORT AND DOCUMENTATION After installing, you can find documentation for this module with the perldoc command. perldoc Net::Address::IP::Cipher You can also look for information at: Github's issue tracker (report bugs here) https://github.com/huguei/p5-Net-Address-IP-Cipher/issues CPAN Ratings http://cpanratings.perl.org/d/Net-Address-IP-Cipher Search CPAN http://search.cpan.org/dist/Net-Address-IP-Cipher/ LICENSE AND COPYRIGHT Copyright (C) 2020 Hugo Salgado This program is free software; you can redistribute it and/or modify it under the terms of the the Artistic License (2.0).
