This may be more hammer for your task than you really need, but I would consider making a memory-mapped file object. Read the data from the two anonymous FDs, concat them into the memory-mapped file object, and pipe those contents to GnuPG. (Note that most people use MMFOs to populate memory blocks with file contents, but there's no requirement it correspond to a physical file on disk: anonymous FDs should work. Also note that I haven't done POSIX memory mapped files in quite some time: my recollections may be off.)
