PMCANON(1)PMCANON(1)NAMEpmcanon - put a news article in canonical format for signature checking
SYNOPSIS
pmcanon[file]
DESCRIPTION
Pmcanon accepts an article from the named file (or standard input if
not specified), selects certain of the header fields, and performs cer‐
tain transformations intended to defeat unintentional mangling by news
transport programs. The resulting article is written to standard out‐
put, and is suitable to have a PGP signature generated or checked for
it.
The output produced consists (in order) of a sorted list, one per line,
of newsgroups; the From:, Subject:, and Message-ID: lines, and the body
of the article (everything after the first empty line). Other header
lines are discarded.
The body is further processed by deleting all blank lines, deleting
trailing whitespace on lines, prefixing lines beginning with "--",
"From", "Subject", and a single "." with "- ", ">", ">" and ".",
respectively. These modifications are safe, in that an article which
has already had such modifications will fail to meet the criterion to
have them happen again. Thus what was used as input when a signature
was generated should still be the same when checked for validity, even
if some of these changes have happened along the delivery path.
