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
