.TH QSSIGN 1 "December 2018" "mod_qos utilities 11.61" "qssign man page" .SH NAME qssign \- an utility to sign and verify the integrity of log data. .SH SYNOPSIS qssign \-s|S [\-e] [\-v] [\-u ] [\-f ] [\-a 'sha1'|'sha256'] .SH DESCRIPTION qssign is a log data integrity check tool. It reads log data from stdin (pipe) and writes the data to stdout adding a sequence number and signatur to ever log line. .SH OPTIONS .TP \-s Passphrase used to calculate signature. .TP \-S Specifies a program which writes the passphrase to stdout. .TP \-e Writes start/end marker when starting/stopping data signing. .TP \-v Verification mode checking the integrity of signed data. .TP \-u Becomes another user, e.g. www\-data. .TP \-f Filter pattern (case sensitive regular expression) for messages which do not need to be signed. .TP \-a 'sha1'|'sha256' Specifes the algorithm to use. Default is sha1. .SH EXAMPLE Sign: TransferLog "|/usr/bin/qssign \-s password \-e |/usr/bin/qsrotate \-o /var/log/apache/access.log" Verify: cat access.log | qssign \-s password \-v .SH SEE ALSO qsdt(1), qsexec(1), qsfilter2(1), qsgeo(1), qsgrep(1), qshead(1), qslog(1), qslogger(1), qspng(1), qsre(1), qsrespeed(1), qsrotate(1), qstail(1) .SH AUTHOR Pascal Buchbinder, http://mod-qos.sourceforge.net/
