Rfc 4880 section 6.2 ( http://tools.ietf.org/html/rfc4880#section-6 ) lists the following header as one of the acceptable ones:
BEGIN PGP MESSAGE, PART X/Y (It assumes ----- before BEGIN and after Y) GnuPG doesn't recognize this, and gives an error message of: $ gpg /cygdrive/c/hflt3dCH.txt.asc gpg: WARNING: using insecure memory! gpg: please see http://www.gnupg.org/faq.html for more information gpg: no valid OpenPGP data found. gpg: processing message failed: eof It does this even when the message is a simple unsplit symmetric message, with only the header and footer changed. here is the file: -----BEGIN PGP MESSAGE, PART 1/2----- Version: GnuPG v1.4.11 (Cygwin) Comment: passphrase = sss jA0EAgMIUjoRauj6Ll9gyS0XpeAXFWQEVfkClC8b7e1YDMpyZsXpa+Hm+N8DZMOd 90PmxTwGso5sgWm+TNw= =kYAM -----END PGP MESSAGE, PART 1/2----- (It decrypts as expected when changing the header and footer back to the standard one). This PART X/Y header is used for pgp commandlines 2.x - 6.x (maybe even current pgp, I don't know, lost my copy of 8.x, and only have 2.x and 6.x) when wanting to break up a long armored message and send it out as parts. Have played around with this, and have managed to send out an armored symmetrically encrypted PGP message of a 500mb truecrypt container file using gmail. Disastry's pgp2.x symmetrically encrypted it and split it into 99 parts each of about 110 k lines, and gave a suffix to each part, (.a01 .a02, ... , .ao99), and after copying each into the same folder, successfully restored and decrypted it, with only a simple command: pgp -filename.a01 (After the correct passphrase for the symmetric encryption was given, it concatenated, decrypted, and restored the original truecrypt container.) Nowadays, with larger e-mail storage, and when people don't trust the 'cloud' for file storage, it might be useful to have gnupg sign, encrypt, armor, and split large files, send them through e- mail, and then decrypt, verify and restore them. just a thought for a 'feature request' of being able to split and reconstitute large files...
