* g10/gpg.c: Include shareddefs.h. (main): Add option --pinentry-mode. * g10/options.h (struct opt): Add field pinentry_mode. * g10/passphrase.c: Include shareddefs.h. (have_static_passphrase): Take care of loopback pinentry_mode. (read_passphrase_from_fd): Ditto. (get_static_passphrase): New. (passphrase_to_dek_ext): Factor some code out to ... (emit_status_need_passphrase): new. * g10/call-agent.c (start_agent): Send the pinentry mode. (default_inq_cb): Take care of the PASSPHRASE inquiry. Return a proper error code. (agent_pksign): Add args keyid, mainkeyid and pubkey_algo. (agent_pkdecrypt): Ditto. * g10/pubkey-enc.c (get_it): Pass new args. * g10/sign.c (do_sign): Pass new args. * g10/call-agent.c (struct default_inq_parm_s): New. Change all similar structs to reference this one. Change all users and inquire callback to use this struct, instead of NULL or some undefined but not used structs. This change will help to eventually get rid of global variables. -- This new features allows to use gpg without a Pinentry. As a prerequisite the agent must be configured to allow the loopback pinentry mode (option --allow-loopback-pinentry). For example gpg2 --pinentry-mode=loopback FILE.gpg may be used to decrypt FILE.gpg while entering the passphrase on the tty. If batch is used, --passphrase et al. may be used, if --command-fd is used, the passphrase may be provided by another process. Note that there are no try-again prompts in case of a bad passphrase.
