14 (pipe) and writes the data to stdout adding a sequence number and sig‐
15 natur to ever log line.

26 -v Verification mode checking the integrity of signed data.

28 -u <name>
29 Becomes another user, e.g. www-data.
30
31 -f <regex>
32 Filter pattern (case sensitive regular expression) for messages
33 which do not need to be signed.

35 -a 'sha1'|'sha256'
36 Specifes the algorithm to use. Default is sha1.
