2015-12-19gpg: Add option --weak-digest to gpg and gpgv.Daniel Kahn Gillmor1-3/+14
* 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.

2014-11-14gpg: Make the use of "--verify FILE" for detached sigs harder.Werner Koch1-10/+17
* g10/openfile.c (open_sigfile): Factor some code out to ... (get_matching_datafile): new function. * g10/plaintext.c (hash_datafiles): Do not try to find matching file in batch mode. * g10/mainproc.c (check_sig_and_print): Print a warning if a possibly matching data file is not used by a standard signatures. -- Allowing to use the abbreviated form for detached signatures is a long standing bug which has only been noticed by the public with the release of 2.1.0. :-( What we do is to remove the ability to check detached signature in --batch using the one file abbreviated mode. This should exhibit problems in scripts which use this insecure practice. We also print a warning if a matching data file exists but was not considered because the detached signature was actually a standard signature: gpgv: Good signature from "Werner Koch (dist sig)" gpgv: WARNING: not a detached signature; \ file 'gnupg-2.1.0.tar.bz2' was NOT verified! We can only print a warning because it is possible that a standard signature is indeed to be verified but by coincidence a file with a matching name is stored alongside the standard signature.

2014-10-03gpg: Add build and runtime support for larger RSA keysDaniel Kahn Gillmor1-0/+9
* configure.ac: Added --enable-large-secmem option. * g10/options.h: Add opt.flags.large_rsa. * g10/gpg.c: Contingent on configure option: adjust secmem size, add gpg --enable-large-rsa, bound to opt.flags.large_rsa. * g10/keygen.c: Adjust max RSA size based on opt.flags.large_rsa * doc/gpg.texi: Document --enable-large-rsa. -- Some older implementations built and used RSA keys up to 16Kib, but the larger secret keys now fail when used by more recent GnuPG, due to secure memory limitations. Building with ./configure --enable-large-secmem will make gpg capable of working with those secret keys, as well as permitting the use of a new gpg option --enable-large-rsa, which let gpg generate RSA keys up to 8Kib when used with --batch --gen-key.
