* gpg: Add a notation with version information to signatures.Werner Koch3 days1-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * common/compliance.c (gnupg_manu_notation_value): New. * g10/build-packet.c (name_value_to_notation): New. * g10/options.h (COMPAT_NO_MANU): New. (LIST_SHOW_HIDDEN_NOTATIONS): New. (VERIFY_SHOW_HIDDEN_NOTATIONS): New. * g10/gpg.c (compatibility_flags): Add "no-manu". (parse_list_options): Add "show-hidden-notations". (main): Ditto for verify-options. * g10/import.c (list_standalone_revocation): Implement new list option. * g10/mainproc.c (check_sig_and_print):Ditto * g10/keyedit.c (keyedit_print_one_sig): Ditto. * g10/keylist.c (list_signature_print): Ditto. (show_notation): Handle hidden notation. * sm/keylist.c (oidtranstbl): Add OID for manu. * g10/sign.c (mk_notation_policy_etc): Add arg with_manu and insert extra notation. (write_signature_packets): Request manu notation in certain cases. (make_keysig_packet): Ditto. -- See DETAILS for a description of the format. Obviously this leaks the version of the used GnuPG version (major and minor only) and the fact that it was generated by GnuPG. However, by close inspection of the order of packets and and other meta data similar information can be found. We include this information to help the support desk to figure out problems. Sometimes users have very very old versions and the help desk needs to employ core developers to figure the cause. Having this information may eventually allow for better user support. This feature can be disabled unless certain compliance modes are enabled.
* gpgsm: Support ECDSA in de-vs mode.Werner Koch2023-11-081-0/+1
| | | | | | | | | | | * common/compliance.h (PK_ALGO_FLAG_ECC18): New. * common/compliance.c (gnupg_pk_is_allowed): Implement. * sm/decrypt.c (gpgsm_decrypt): Pass new flag. * sm/sign.c (gpgsm_sign): Ditto. * sm/verify.c (gpgsm_verify): Ditto. -- GnuPG-bug-id: 6802
* sm: Fix compliance checking for ECC signature verification.Werner Koch2023-01-121-1/+1
| | | | | | | | | | | * common/compliance.c (gnupg_pk_is_compliant): Also consider the gcrypt vids for ECDSA et al. (gnupg_pk_is_allowed): Ditto. * sm/verify.c (gpgsm_verify): Consider the curve. Print a compliance notice for a non-compliant key. * sm/certchain.c (gpgsm_validate_chain): Silence the "switching to chain model".
* gpg,gpgsm: Add option --min-rsa-length.Werner Koch2021-11-181-0/+2
| | | | | | | | | | | | | | | * common/compliance.c (min_compliant_rsa_length): New. (gnupg_pk_is_compliant): Take in account. (gnupg_pk_is_allowed): Ditto. (gnupg_set_compliance_extra_info): New. * g10/gpg.c (oMinRSALength): New. (opts): Add --min-rsa-length. (main): Set value. * g10/options.h (opt): Add field min_rsa_length. * sm/gpgsm.c (oMinRSALength): New. (opts): Add --min-rsa-length. (main): Set value. * sm/gpgsm.h (opt): Add field min_rsa_length.
* Include the library version in the compliance checks.Werner Koch2021-01-281-0/+1
| | | | | | | | | | | | | | | | | | * common/compliance.c (gnupg_gcrypt_is_compliant): New. (gnupg_rng_is_compliant): Also check library version. * g10/mainproc.c (proc_encrypted): Use new function. (check_sig_and_print): Ditto. * sm/decrypt.c (gpgsm_decrypt): Ditto. * sm/encrypt.c (gpgsm_encrypt): Ditto. * sm/verify.c (gpgsm_verify): Ditto -- This will eventually allow us to declare Libgcrypt 1.9 to be de-vs compliant. GnuPG can use this information then for its own checks. As of now GnuPG tests the version of the used library but that is a bit cumbersome to maintain. Signed-off-by: Werner Koch <[email protected]>

| | | | | | | | | | | | | | | * common/compliance.h (PK_ALGO_FLAG_RSAPSS): New. * common/compliance.c (gnupg_pk_is_compliant): Add arg alog_flags and test rsaPSS. Adjust all callers. (gnupg_pk_is_allowed): Ditto. * sm/misc.c (gpgsm_ksba_cms_get_sig_val): New wrapper function. (gpgsm_get_hash_algo_from_sigval): New. * sm/certcheck.c (gpgsm_check_cms_signature): Change type of sigval arg. Add arg pkalgoflags. Use the PK_ALGO_FLAG_RSAPSS. * sm/verify.c (gpgsm_verify): Use the new wrapper and new fucntion to also get the algo flags. Pass algo flags along. Signed-off-by: Werner Koch <[email protected]>

| | | | | | | | * g10/gpg.c: Make --pgp6 an alias for --pgp7. * common/compliance.h (gnupg_compliance_mode): Remove CO_PGP6. * g10/options.h (PGP6): Remove. Adjust all users. Signed-off-by: Werner Koch <[email protected]>
* gpg,sm: Check compliance of the RNG.Werner Koch2017-07-171-0/+2
| | | | | | | | | | | | | | | | | | * common/compliance.c (gnupg_rng_is_compliant): New. * g10/call-agent.c (start_agent) [W32]: Check rng compliance. * sm/call-agent.c (start_agent) [W32]: Ditto. * g10/encrypt.c (encrypt_simple, encrypt_crypt): Check that the RNG is compliant. * sm/encrypt.c (gpgsm_encrypt): Ditto. * g10/sign.c (do_sign): Ditto. * sm/sign.c (gpgsm_sign): Ditto. -- Under Windows we need to check that the Jitter RNG is active in de-vs mode. Under Linux this is not necessary because /dev/random can be scrutinized and is believed to provide enough entropy. Signed-off-by: Werner Koch <[email protected]>
* gpg,gpgsm: Fix compliance check for DSA and avoid an assert.Werner Koch2017-06-191-4/+8
| | | | | | | | | | | | | | | | | | | * common/compliance.c (gnupg_pk_is_compliant): Swap P and Q for DSA check. Explicitly check for allowed ECC algos. (gnupg_pk_is_allowed): Swap P and Q for DSA check. * g10/mainproc.c (proc_encrypted): Simplify SYMKEYS check. Replace assert by debug message. -- Note that in mainproc.c SYMKEYS is unsigned and thus a greater than 0 condition is surprising because it leads to the assumption SYMKEYS could be negative. Better use a boolean test. The assert could have lead to a regression for no good reason. Not being compliant is better than breaking existing users. Signed-off-by: Werner Koch <[email protected]>
