* gpg: Add option --weak-digest to gpg and gpgv.Daniel Kahn Gillmor2015-10-191-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * g10/options.h: Add additional_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; use proper gcry_md_algos type. * g10/sig-check.c: (do_check): Reject weak digests in addition to MD5. * 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 still always considered weak, regardless of any further --weak-digest options supplied. Signed-off-by: Daniel Kahn Gillmor <[email protected]> Capitialized some comments, shorted a line in do_check, and changed subject to name the option. -wk

* common: Add a global variable to for the default error source.Werner Koch2012-02-061-0/+1
| | | | | | | | | | | | | | For the shared code parts it is cumbersome to pass an error sourse variable to each function. Its value is always a constant for a given binary and thus a global variable makes things a lot easier than the former macro stuff. * common/init.c (default_errsource): New global var. (init_common_subsystems): Rename to _init_common_subsystems. Set DEFAULT_ERRSOURCE. * common/init.h: Assert value of GPG_ERR_SOURCE_DEFAULT.

| | | | | | | | | | | | | | | | * g10/gpgv.c, g10/trustdb.c (read_trust_options): Add min_cert_level * g10/trustdb.c (check_trustdb_stale): Request a rebuild if pending_check_trustdb is true (set when we detect a trustdb parameter has changed). * g10/keylist.c (public_key_list): Use 'l' in the "tru" with-colons listing for min_cert_level not matching. * g10/tdbio.c (tdbio_update_version_record, create_version_record, tdbio_db_matches_options, tdbio_dump_record, tdbio_read_record, tdbio_write_record): Add a byte for min_cert_level in the tdbio version record.
* Add a flag parameter to dotlock_create.Werner Koch2011-09-281-1/+2

* Nuked almost all trailing white space.post-nuke-of-trailing-wsWerner Koch2011-02-041-32/+31
| | | | | | | | We better do this once and for all instead of cluttering all future commits with diffs of trailing white spaces. In the majority of cases blank or single lines are affected and thus this change won't disturb a git blame too much. For future commits the pre-commit scripts checks that this won't happen again.
