lr_deanonymize - restore anonymized data, using a dump as produced by lr_anonymize(1)

lr_deanonymize dumpfilestem

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).

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
