name identifies a certificate unambiguously. (gpgsm_find_cert): Ditto. * server.c (cmd_listkeys): Check that the data stream is available. (cmd_listsecretkeys): Ditto. (has_option): New. (cmd_sign): Fix ambiguousity in option recognition. * gpgsm.c (main): Enable --logger-fd. * encrypt.c (gpgsm_encrypt): Increased buffer size for better performance. * call-agent.c (gpgsm_agent_pksign): Check the S-Exp received from the agent. * keylist.c (list_cert_colon): Filter out control characters.
