Hi GnuPG folks--
i'd like to use gpg to verify a detached signature, but for various
reasons i don't want to put either part (the body or the signature) in
the filesystem (i have the data queued in two otherwise anonymous file
if i put the body on FD 0, i can verify the detached signature with:
gpg --verify sig -
but i still need to have the signature in a file in the file system. Is
there a way to tell gpg to read the sig itself from a file descriptor as
On some operating systems (in some configurations) it looks like i can
use (e.g.) /proc/self/fd/3 to read the signature from file descriptor 3,
but it would be nice to be more portable than that.
Thanks for gpg,
