* agent: Make --disable-extended-key-format a dummy option.Werner Koch2023-03-131-1/+1
| | | | | | | | | | | | | | | | | | | | | * agent/agent.h (opt): Remove enable_extended_key_format. * agent/gpg-agent.c (enum cmd_and_opt_values): Turn oDisableExtendedKeyFormat and oEnableExtendedKeyFormat into dummy options. * agent/protect.c (do_encryption): Remove arg use_ocb and corresponding code. (agent_protect): Ditto. Change all callers. * agent/findkey.c (agent_write_private_key): Simplify due to the removal of disable-extended-key-format. (write_extended_private_key): Fold into agent_write_private_key. -- This change is related to GnuPG-bug-id: 6386 but should have no visible effect except for the removal of option --disable-extended-key-format.
* build: Always use EXTERN_UNLESS_MAIN_MODULE pattern.Werner Koch2020-02-101-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | * common/util.h (EXTERN_UNLESS_MAIN_MODULE): Add the definion only here but now without the Norcroft-C. Change all other places where it gets defined. * common/iobuf.h (iobuf_debug_mode): Declare unconditionally as extern. * common/iobuf.c (iobuf_debug_mode): Define it here. * agent/gpg-agent.c (INCLUDED_BY_MAIN_MODULE): Define here and also in all main modules of all other programs. * g10/main.h: Put util.h before the local header files. -- This change is required for use with gcc/ld's LTO feature which does not allow common blocks. Further gcc 10 will make -fno-common the default and thus this chnage is always needed. What a pitty.

* agent: Use clock or clock_gettime for calibration.NIIBE Yutaka2017-11-201-1/+1
| | | | | | | | | | | | | | | | | | * agent/protect.c (calibrate_get_time): Use clock or clock_gettime. -- For calibration, clock(3) is better than times(3) among UNIXen. Tested on NetBSD 7.1 and FreeBSD 11.1, using QEMU. Thanks to Damien Goutte-Gattat for the information of use of CLOCKS_PER_SEC; The old code with times(3) is not 100% correct, in terms of POSIX. It should have used sysconf (_SC_CLK_TCK) instead of CLOCKS_PER_SEC. CLOCKS_PER_SEC is specifically for clock(3).

* agent: Implement new protection mode openpgp-s2k3-ocb-aes.Werner Koch2016-04-121-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * agent/protect.c (agent_protect): Add arg use_ocb. Change all caller to pass -1 for default. * agent/protect-tool.c: New option --debug-use-ocb. (oDebugUseOCB): New. (opt_debug_use_ocb): New. (main): Set option. (read_and_protect): Implement option. * agent/protect.c (OCB_MODE_SUPPORTED): New macro. (PROT_DEFAULT_TO_OCB): New macro. (do_encryption): Add args use_ocb, hashbegin, hashlen, timestamp_exp, and timestamp_exp_len. Implement OCB. (agent_protect): Change to support OCB. (do_decryption): Add new args is_ocb, aadhole_begin, and aadhole_len. Implement OCB. (merge_lists): Allow NULL for sha1hash. (agent_unprotect): Change to support OCB. (agent_private_key_type): Remove debug output. -- Instead of using the old OpenPGP way of appending a hash of the plaintext and encrypt that along with the plaintext, the new scheme uses a proper authenticated encryption mode. See keyformat.txt for a description. Libgcrypt 1.7 is required. This mode is not yet enabled because there would be no way to return to an older GnuPG version. To test the new scheme use gpg-protect-tool: ./gpg-protect-tool -av -P abc -p --debug-use-ocb <plain.key >prot.key ./gpg-protect-tool -av -P abc -u <prot.key Any key from the private key storage should work.

* Implement unattended OpenPGP secret key import.Werner Koch2013-05-221-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * agent/command.c (cmd_import_key): Add option --unattended. * agent/cvt-openpgp.c (convert_transfer_key): New. (do_unprotect): Factor some code out to ... (prepare_unprotect): new function. (convert_from_openpgp): Factor all code out to ... (convert_from_openpgp_main): this. Add arg 'passphrase'. Implement openpgp-native protection modes. (convert_from_openpgp_native): New. * agent/t-protect.c (convert_from_openpgp_native): New dummy fucntion * agent/protect-tool.c (convert_from_openpgp_native): Ditto. * agent/protect.c (agent_unprotect): Add arg CTRL. Adjust all callers. Support openpgp-native protection. * g10/call-agent.c (agent_import_key): Add arg 'unattended'. * g10/import.c (transfer_secret_keys): Use unattended in batch mode. -- With the gpg-agent taking care of the secret keys, the user needs to migrate existing keys from secring.gpg to the agent. This and also the standard import of secret keys required the user to unprotect the secret keys first, so that gpg-agent was able to re-protected them using its own scheme. With many secret keys this is quite some usability hurdle. In particular if a passphrase is not instantly available. To make this migration smoother, this patch implements an unattended key import/migration which delays the conversion to the gpg-agent format until the key is actually used. For example: gpg2 --batch --import mysecretkey.gpg works without any user interaction due to the use of --batch. Now if a key is used (e.g. "gpg2 -su USERID_FROM_MYSECRETKEY foo"), gpg-agent has to ask for the passphrase anyway, converts the key from the openpgp format to the internal format, signs, re-encrypts the key and tries to store it in the gpg-agent format to the disk. The next time, the internal format of the key is used. This patch has only been tested with the old demo keys, more tests with other protection formats and no protection are needed.

* ssh: Support ECDSA keys.Werner Koch2012-12-121-2/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * agent/command-ssh.c (SPEC_FLAG_IS_ECDSA): New. (struct ssh_key_type_spec): Add fields CURVE_NAME and HASH_ALGO. (ssh_key_types): Add types ecdsa-sha2-nistp{256,384,521}. (ssh_signature_encoder_t): Add arg spec and adjust all callers. (ssh_signature_encoder_ecdsa): New. (sexp_key_construct, sexp_key_extract, ssh_receive_key) (ssh_convert_key_to_blob): Support ecdsa. (ssh_identifier_from_curve_name): New. (ssh_send_key_public): Retrieve and pass the curve_name. (key_secret_to_public): Ditto. (data_sign): Add arg SPEC and change callers to pass it. (ssh_handler_sign_request): Get the hash algo from SPEC. * common/ssh-utils.c (get_fingerprint): Support ecdsa. * agent/protect.c (protect_info): Add flag ECC_HACK. (agent_protect): Allow the use of the "curve" parameter. * agent/t-protect.c (test_agent_protect): Add a test case for ecdsa. * agent/command-ssh.c (ssh_key_grip): Print a better error code. -- The 3 standard curves are now supported in gpg-agent's ssh-agent protocol implementation. I tested this with all 3 curves and keys generated by OpenSSH 5.9p1. Using existing non-ssh generated keys will likely fail for now. To fix this, the code should first undergo some more cleanup; then the fixes are pretty straightforward. And yes, the data structures are way too complicated.
* Change all quotes in strings and comments to the new GNU standard.Werner Koch2012-06-051-2/+2
| | | | | | | | | | | | | | | | | | | The asymmetric quotes used by GNU in the past (`...') don't render nicely on modern systems. We now use two \x27 characters ('...'). The proper solution would be to use the correct Unicode symmetric quotes here. However this has the disadvantage that the system requires Unicode support. We don't want that today. If Unicode is available a generated po file can be used to output proper quotes. A simple sed script like the one used for en@quote is sufficient to change them. The changes have been done by applying sed -i "s/\`\([^'\`]*\)'/'\1'/g" to most files and fixing obvious problems by hand. The msgid strings in the po files were fixed with a similar command.
* Added gpg-agent OPTION "s2k-count".Ben Kibbey2011-06-291-1/+1
| | | | When unset or 0, the calibrated count will be used.
* Nuked almost all trailing white space.post-nuke-of-trailing-wsWerner Koch2011-02-041-6/+6
| | | | | | | | 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.
