First: I don't have any experience w/ PGP, but I have and use GPG. Bug severity: fairly minor GPG has a command line option to choose the digest algorithm when making signatures. Mutt has the ability to select this algorithm too, but from what I've seen in a cursory examination of the code, the only place the selected value is used is in the MIME header. Perhaps in pgpinvoke.c there could be an additional % escape for PgpSignMicalg in the format callback function? That would allow GPG (and possibly PGP) to select the same algo as Mutt puts in the header. Mutt by default will choose MD5, while GPG will use SHA-1. -- Oooooo-oooo-oooo-ooooo, Oooooo-oooo-oooo-ooooo, Ooooo-weem-oh-wum-ooo-ayyy In the jungle, the silicon jungle, the process sleeps tonight.
