* gpg: Add option --weak-digest to gpg and gpgv.Daniel Kahn Gillmor2015-12-198-18/+92
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * g10/options.h: Add weak_digests linked list to opts. * g10/main.h: Declare weakhash linked list struct and additional_weak_digest() function to insert newly-declared weak digests into opts. * g10/misc.c: (additional_weak_digest): New function. (print_digest_algo_note): Check for deprecated digests. * g10/sig-check.c: (do_check): Reject all weak digests. * g10/gpg.c: Add --weak-digest option to gpg. * doc/gpg.texi: Document gpg --weak-digest option. * g10/gpgv.c: Add --weak-digest option to gpgv. * doc/gpgv.texi: Document gpgv --weak-digest option. -- gpg and gpgv treat signatures made over MD5 as unreliable, unless the user supplies --allow-weak-digests to gpg. Signatures over any other digest are considered acceptable. Despite SHA-1 being a mandatory-to-implement digest algorithm in RFC 4880, the collision-resistance of SHA-1 is weaker than anyone would like it to be. Some operators of high-value targets that depend on OpenPGP signatures may wish to require their signers to use a stronger digest algorithm than SHA1, even if the OpenPGP ecosystem at large cannot deprecate SHA1 entirely today. This changeset adds a new "--weak-digest DIGEST" option for both gpg and gpgv, which makes it straightforward for anyone to treat any signature or certification made over the specified digest as unreliable. This option can be supplied multiple times if the operator wishes to deprecate multiple digest algorithms, and will be ignored completely if the operator supplies --allow-weak-digests (as before). MD5 is always considered weak, regardless of any further --weak-digest options supplied.

| | | | | | | | * g10/passphrase.c (stdenvnames): Add DBUS_SESSION_BUS_ADDRESS. -- pinentry-gnome3 talks to the gcr prompter via dbus. Without this environment variable, it can't find the correct session to talk to.
* gpg: Avoid cluttering stdout with trustdb info in verbose mode.Werner Koch2015-11-201-1/+1
| | | | | | | | | | | | | | | | * g10/trustdb.c (validate_keys): Call dump_key_array only in debug mode. -- I guess that is a left-over from an early attempt to output information on the trustdb for use by other tools. Maybe related to the former --list-trust-path command. Sending it to stdout is probably useful so we do this now only in debug mode.

(USE_DNS_PKA): Remove ac_define. * g10/getkey.c (parse_auto_key_locate): Always include PKA. -- Note that although PKA is now always build, it will only work if support for looking up via DNS has not been disabled. The new PKA only works with the IPGP DNS certtype and shall be used only to retrieve the fingerprint and optional the key for the first time. Due to the security problems with DNSSEC the former assumption to validate the key using DNSSEC is not anymore justified. Instead an additional layer (e.g. Trust-On-First-Use) needs to be implemented to track change to the key. Having a solid way of getting a key matching a mail address is however a must have. More work needs to go into a redefinition of the --verify-options pka-lookups and pka-trust-increase. The auto-key-locate mechanism should also be able to continue key fetching with another method once the fingerprint has been retrieved with PKA.
