Hello List, I'm trying to use gnupg to solve a usecase similar to the one depicted in [1], but the workaround from [1] is not suitable, because:
* Each file I have is larger than the machine holding the keys * The keys cannot be moved * The streams will take hours/days to decrypt so no interruption is possible. I would use following scheme to solve it: * Have wrapper passing stdin (fd=0) unmodified to newly forked gnupg instance * Read passwords from tty not stdin If I understand correctly, gnupg will not overread on stdin, so no packet headers will be consumed on error by previous gnupg process on error after finishing the payload packet. A problem that remains: I have to make gnupg ask for each key password indefinitely long. As gnupg needs to read the header to find the correct private key, termination after the 3rd password would break the stream. Is there any way to make gpg repeat the password question over and over? Not yet applicable, but perhaps for next level: Same for keyring with multiple keys, but where encrypted content was created with "--throw-key-ids".
