a true type font for windows
where the characters are not displayable or printable
here is a zipfile (ifw2kxp) with the following files:
- invisible1.ttf ( a true-type font for windows 2k/nt/xp )
- ifreadme.asc ( a pgp clearsigned readme file, explaining the invisible font and its usage )
- aifs.pdf (a pdf file with an armored signed pgp message enbedded in it, using invisible font)
the zipfile 'ifw2kxp.zip' is here:
When a document is rendered in pdf, empty lines are rendered as whitespace, rather than as a line return.
This results in a 'functional' omission of the 'empty line' in pgp messages.
The standard for open pgp messages, is that there needs to be an empty line between the last line of the pgp header, and the beginning of the radix 64 armor of the pgp message block.
This is primarily for aesthetic effect, but some implementations will not process the message if the empty line is absent.
(All versions of PGP will decrypt/verify the message even in the absence of the 'empty line',
while earlier versions of GnuPG will give an error message of 'improper header' and halt further processing.
The 1.4.2 version 'does' accept the message in absence of the empty line.)
'Invisible font' is unrestricted freeware.
Enjoy, Improve, Distribute freely ;-)
