E.g., PGP 2.x. I can't speak for all of them, but PGP 2.x does indeed do that as long as you give it the -t flag. Whether the standard tools for checking such messages do that or not, I don't know (but they should). > RFC 1991 does not mention "whitespace", "trailing", or "strip".

It's still relatively widely used for newsgroup control messages just because that's the PGP that tale originally used, nearly all the keys are RSA, and GnuPG couldn't handle RSA keys until about a year ago. Outside of that, I'm seeing rapidly diminishing popularity. > For pure-ASCII, no trailing whitespace, no possibly dash escaped text, > use of inline isn't that bad, especially for announcements stored in > files -- PGP/MIME is too e-mail specific to be used in that case.
