qssign(1) an utility to sign and verify the integrity of log data.

SYNOPSIS

qssign -s|S <secret> [-e] [-v] [-u <name>] [-f <regex>] [-a 'sha1'|'sha256']

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.

OPTIONS

-s <secret>
Passphrase used to calculate signature.
-S <program>
Specifies a program which writes the passphrase to stdout.
-e
Writes end marker when stopping data signing.
-v
Verification mode checking the integrity of signed data.
-u <name>
Becomes another user, e.g. www-data.
-f <regex>
Filter pattern (case sensitive regular expression) for messages which do not need to be signed.
-a 'sha1'|'sha256'
Specifes the algorithm to use. Default is sha1.

EXAMPLE

Sign:


 TransferLog "|/bin/qssign -s password -e |/bin/qsrotate -o /var/log/apache/access_log"
