Why convert ASC to PDF?
An OpenPGP .asc file is ASCII-armored Base64 text wrapping one of three things: a detached digital signature, a public key, or an encrypted message. None of these has text, fonts, or graphics to lay out on a page. .pdf is a page-description format that requires renderable content an OpenPGP block simply does not contain.
How to convert ASC to PDF
GnuPG (decrypt first, then export PDF) FREE
If the .asc is an encrypted message, run gpg --decrypt message.asc to recover the original file; if that file is a document, open it in its native application and export to PDF from there.
Kleopatra / Gpg4win (Windows) FREE
Use Kleopatra on Windows to decrypt a .asc PGP message; once decrypted, open the resulting document and export it to PDF using any application's built-in export.
