--- name: "lr_deanonymize" section: "1" platform: "linux" package: "lire" version: "2.1.1-8" release: "Arch Linux 2026-11-01" platforms: ["linux"] url: "https://new.carta.tech/lr_deanonymize" --- # lr\_deanonymize(1) restore anonymized data, using a dump as produced by lr\_anonymize(1) ## NAME lr\_deanonymize - restore anonymized data, using a dump as produced by [lr\_anonymize(1)](/lr_anonymize/1.md) ## SYNOPSIS **lr\_deanonymize** *dumpfilestem* ## DESCRIPTION **lr\_deanonymize** is typically used when receiving anonymized reports from a responder. See the section on "Processing The Responder's Results" in the chapter on "Using A Responder" in the Lire User Manual for usage examples. **lr\_deanonymize** reads a file containing anonymized emailaddresses, ipnumbers, and hostnames (typically a report, generated from a logfile from an internet service) from stdin, and prints a "deanonymized" version of this file to stdout. It reads its information to do this from a bunch of Berkeley DB's, stored in files whose's names are derived from *dumpfilestem*, as produced by [**lr\_anonymize**(1)](/lr_anonymize/1.md). ## EXAMPLE A 'logfile' like e.g. ``` blaat fkrf 1.2.3.4.in-addr.arpa] pietje@bigcompany.com bla 1 2 3 lj;agas;gag blaat 1.2.3.4 fkrf 3.2.3.4.in-addr.arpa] bla 1 www.hotsex.com 2 3 lj;agas;gag jan@blaat.frut.com agagag blaat fkrf 4.2.3.4.in-addr.arpa] bla pietje@bigcompany.com www.hotsex.com 234.34.2.0 jan@blaat.frut.com 4.2.3.4.in-addr.arpa1 2 3 lj;agas;gag blaat fkrf tweede 3.2.3.4.in-addr.arpa] bla 1.2.3.4 1 blablabla.com 2 mdcc.cx 3 lj;agas;gag ``` wil get anonymized to ``` blaat fkrf 1.0.0.10.in-addr.arpa] john.doe.1@example.com bla 1 2 3 lj;agas;gag blaat 10.0.0.1 fkrf 2.0.0.10.in-addr.arpa] bla 1 1.example.com 2 3 lj;agas;gag john.doe.2@example.com agagag blaat fkrf 3.0.0.10.in-addr.arpa] bla john.doe.1@example.com 1.example.com 10.0.0.2 john.doe.2@example.com 3.0.0.10.in-addr.arpa1 2 3 lj;agas;gag blaat fkrf tweede 2.0.0.10.in-addr.arpa] bla 10.0.0.1 1 2.example.com 2 3.example.com 3 lj;agas;gag ``` The dump will look like ``` ip 234.34.2.0 10.0.0.2 ip 1.2.3.4 10.0.0.1 inaddr 3.2.3.4.in-addr.arpa 2.0.0.10.in-addr.arpa inaddr 1.2.3.4.in-addr.arpa 1.0.0.10.in-addr.arpa inaddr 4.2.3.4.in-addr.arpa 3.0.0.10.in-addr.arpa domain mdcc.cx 3.example.com domain blablabla.com 2.example.com domain www.hotsex.com 1.example.com email jan@blaat.frut.com john.doe.2@example.com email pietje@bigcompany.com john.doe.1@example.com ``` ## SEE ALSO [**lr\_anonymize**(1)](/lr_anonymize/1.md) ## VERSION `$Id:` lr\_deanonymize.in,v 1.4 2006/07/23 13:16:32 vanbaal Exp $ ## COPYRIGHT Copyright (C) 2000-2001 Stichting LogReport Foundation LogReport@LogReport.org This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version.
