(decrypt_data): Add --no-options. (verify_signature): Ditto. (new_part): Check for Wks-Draft-Version header. Take care of text parts. (wks_receive): Set Parser and pass a flag value to RESULT_CB. * tools/gpg-wks-client.c (read_confirmation_request): New. (main) <aRead>: Call read_confirmation_request instead of process_confirmation_request. (command_receive_cb): Ditto. Add arg FLAGS.. (decrypt_stream_status_cb, decrypt_stream): New. (command_send): Set header Wks-Draft-Version. * tools/gpg-wks-server.c (struct server_ctx_s): Add field DRAFT_VERSION_2. (sign_stream_status_cb, sign_stream): New. (command_receive_cb): Set draft flag. (send_confirmation_request): Rework to implement protocol draft version 2. * tools/gpg-wks.h (DBG_MIME_VALUE, DBG_PARSER_VALUE): New. (DBG_MIME, DBG_PARSER, DBG_CRYPTO): New. Use instead of a plain opt.debug where useful. * tools/gpg-wks-client.c (debug_flags): Add "mime" and "parser". * tools/gpg-wks-server.c (debug_flags): Ditto.
If a client supporting the version 2 of the protocol is used, it will
tell this the server using a mail header. An old server will ignore
that but a recent server will use the new protocol. Next task is to
actually write draft-02.
There are still a lot of FIXMEs - take care.
