* core: Add GPGME_KEYLIST_MODE_WITH_TOFU.Werner Koch2016-08-251-0/+5
| | | | | | | | | | | | | | | | * src/gpgme.h.in (GPGME_KEYLIST_MODE_WITH_TOFU): New. * src/engine-gpg.c (gpg_keylist_build_options): Use that. * src/keylist.c: Include limits.h. (parse_tfs_record): New. (keylist_colon_handler): Support TFS record. * tests/run-keylist.c: Include time.h. (isotimestr): New. (main): Add option --tofu. Print TOFU info. * tests/run-verify.c: Include time.h. (isotimestr): New. (print_result): Use isotimestr for TOFU dates. Signed-off-by: Werner Koch <[email protected]>
* core: Change the way TOFU information are represented.Werner Koch2016-08-231-2/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | * src/gpgme.h.in (struct _gpgme_signature): Remove field 'tofu'. Add field 'key'. (struct _gpgme_key): Add field 'fpr'. (struct _gpgme_user_id): Add field 'tofu'. (struct _gpgme_tofu_info): Remove fields 'address' and 'fpr'. * src/key.c (gpgme_key_unref): Release TOFU and FPR. * src/keylist.c (keylist_colon_handler): Store the fingerprint of the first subkey also in KEY. * src/verify.c (release_tofu_info): Remove.

What is missing is a way to return that information to the application after decryption/verification.
