Abstract

PGP/MIME provides single signature service of PGP in the context of MIME, however, multiple signature service is desired for usability and flexibility. For this purpose, this memo defines 'Multipart/PGP-Signature' used as the 'protocol' parameter and the content type of the second part of 'Multipart/Signed'. Canonical MIME format used in PGP/MIME is reasonable but it is not enough for some kinds of MIME objects, particularly for ISO 2022 text. Thus, this memo extends the 'micalg' parameter syntax as 'pgp-<hash-symbol>+<canform-symbol>' so that <canform-symbol> can specify more specific canonicalization for signature calculation.
