[Please consider the following wishlist item regarding Crypt-OpenPGP-1.04.] [Please consider me an OpenPGP newbie.] Currently, the Crypt::OpenPGP::Signature constructor expects the actual signature data to be passed. However, it should be just as well be possible to substitute a pre-computed digest for the data (as, IIUC, all the constructor has to do with the data is to compute the digest.) This way, Alice could compute SHA-1 at work, write it on a piece of paper, and then, after returning home, produce a digital signature for the original file without bringing it with her. Or, Bob could extract the digests from the Debian-signed Packages list file and sign individual Debian packages without actually downloading them. (But actually, I've been thinking about inventing yet another digital signature format, which, thanks to the function requested, it would be easy to convert into an OpenPGP signature.) -- FSF associate member #7257.
