* common/util.h (GPG_ERR_BAD_RESET_CODE): New replacement. (GPG_ERR_NO_RESET_CODE): New. (GPG_ERR_BAD_PUK): New. -- But as least 1.38 is required. Tested with 1.42
2024-02-05common: Update requisitesÁngel González1-4/+0
* configure.ac: Require libgpg-error 1.38 and libksba 1.4.0 * common/util.h: Remove error number substitutes. -- These versions were already needed for a successful compilation, but it was not reflected by configure. GnuPG-bug-id: 6974 Signed-off-by: Ángel González <[email protected]> util.h patch by wk.
2023-09-29common: Add new function b64decode.Werner Koch1-0/+2
* common/b64dec.c (b64decode): New. * common/t-b64.c: Change license to LGPL. (oops): New macro. (hex2buffer): New. (test_b64decode): New. (main): Default to run the new test. * common/Makefile.am (module_maint_tests): Move t-b64 to ... (module_tests): here. -- Sometimes we have a short base64 encoded string we need todecode. This function makes it simpler. License change of the test module justified because I am the single author of the code.
2023-01-19gpg: Detect already compressed data also when using a pipe.Werner Koch1-1/+1
* common/iobuf.c (file_filter_ctx_t): Add fields for the peek feature. (file_filter): Implement peeking. (iobuf_ioctl): Add new IOBUF_IOCTL_PEEK. * common/iobuf.h (IOBUF_IOCTL_PEEK, IOBUFCTRL_PEEK): New. * common/miscellaneous.c (is_file_compressed): Rewrite. Detect PDF. * g10/encrypt.c (encrypt_simple): Peek before detecting compression.

GnuPG-bug-id: 6332 Backported-from-master: 60963d98cfd8e60f88ee43c2d992f6dd3bbbd74c Note that sign.c (sign_file) has been re-indented to ease future backports.
2023-01-13common: New function get_keyalgo_string.Werner Koch1-0/+3
* common/openpgp-oid.c (struct keyalgo_string_s): New. (keyalgo_strings): New. (keyalgo_strings_size, keyalgo_strings_used): New. (openpgp_oid_or_name_to_curve): New. (get_keyalgo_string): New. -- This function is intended as a more general version of gpg's pubkey_string function. It has the advantage to avoid mallocs and uses static table of algorithm strings instead. There should be only a few dozen of such strings (if at all) and thus all those allocations we do internally in gpg's pubkey_string and the static buffers all over the place are not too nice.

* common/homedir.c (is_gnupg_default_homedir): Use standard_homedir instead of the constant which makes a difference on Windows. (_gnupg_socketdir_internal) [W32]: Move the directory to LOCAL_APPDATA. (gnupg_cachedir): Remove unsued function. * common/sysutils.c (gnupg_rmdir): New. * tools/gpgconf.c (main): s/rmdir/gnupg_rmdir/. -- That is actually a more correct directory than APPDATA. This fixes a problem with installations where the APPDATA is non a network drive and the resulting socket filename is truncated in our socket helper function (because we use sockaddr also for our local socket emulation on Windows). LOCAL_APPDATA is expected to be on the local box and thus in the majority of cases the resulting socket file name will be short enough.

Use new function in most places where fopen is used. -- The config files in 2.2 are still read using fopen - we need to change this to allow Unicode directory names.

* configure.ac: Require libgpg-error 1.25. * common/util.h: Define some extra error codes. -- This actually defines a few more error ocdes in case they are used by backported code.

(do_sign): Support SHA-256 and >2048 bit RSA keys. common/scd:p15: Support signing with CardOS 5 cards. * common/util.h (KEYGRIP_LEN): New. -- This has been tested with a D-Trust card featuring 3072 bit keys. Note that non-repudiation key for a qualified signature does not yet work because we do not yet support rsaPSS padding. Thus a gpgsm --learn shows a couple of Bad Signature errors for this key. Signed-off-by: Werner Koch <[email protected]> Back ported from master: - Removed do_with_keygrip - Added KEYGRIP_LEN - app_help_get_keygrip_string_pk actually added. - Move keygrip_from_prkdf in do_sign before the verification.

2016-06-08Implement /run/user/UID/gnupg based sockets.Werner Koch1-0/+3
* common/homedir.c: Include sys/stat.h and zb32.h. (w32_portable_app, w32_bin_is_bin): Change type from int to byte. (non_default_homedir): New. (is_gnupg_default_homedir): New. (default_homedir): Set non_default_homedir. (gnupg_set_homedir): Set non_default_homedir and make the_gnupg_homedir and absolute directory name. (gnupg_homedir): Return an absolute directory name. (_gnupg_socketdir_internal): New. (gnupg_socketdir): Implement /run/user/ based sockets. * tools/gpg-connect-agent.c (get_var_ext): Replace now obsolete make_filename by xstrdup. * tools/gpgconf.c (main): Sue gnupg_homedir for the "homedir:" output. -- If a [/var]/run/user/$(id -u)/ directory exists, a gnupg subdir is created as needed and the permissions of the directories are checked. If that all matches that directory name is returned instead of the homedir. To cope with non standard homedirs (via GNUPGHOME or --homedir) the SHA-1 hash of the homedir is computed, left truncated to 120 bits, zBase-32 encoded, prefixed with "d.", and appended to "[/var]/run/user/$(id -u)/gnupg/". If that directory exists and has proper permissions it is returned as socket dir - if not the homedir is used. Due to cleanup issues, this directory will not be auto-created but needs to be created by the user in advance. The required permissions are: directory owned by the user, group and others bits not set. Signed-off-by: Werner Koch <[email protected]>

2016-06-07Replace use of opt.homedir by accessor functions.Werner Koch1-0/+2
* common/homedir.c (the_gnupg_homedir): New var. (gnupg_set_homedir): New. (gnupg_homedir): New. * g10/options.h (struct opt): Remove 'homedir' and replace all users by the new accessor functions. * g13/g13-common.h (struct opt): Ditto. * scd/scdaemon.h (struct opt): Ditto. * sm/gpgsm.h (struct opt): Ditto. * dirmngr/dirmngr.h (struct opt): Ditto. * agent/preset-passphrase.c (opt_homedir): Ditto. * agent/protect-tool.c (opt_homedir): Ditto. -- This will make detection of a non-default homedir easier.

2016-06-02common: New function openpgp_is_curve_supported.Werner Koch1-1/+1
* common/openpgp-oid.c: Include openpgpdefs.h. (oidtable): Add field pubkey_algo. (openpgp_is_curve_supported): New. -- Signed-off-by: Werner Koch <[email protected]>
2016-04-25common: Use new function to print a failure of xtrymalloc.Werner Koch1-0/+3
* common/miscellaneous.c (xoutofcore): New. * common/strlist.c (append_to_strlist): Use instead of abort. (append_to_strlist_try): Use xtrymalloc instead of xmalloc. Signed-off-by: Werner Koch <[email protected]>
2016-04-21common: Add support for the new extended private key format.Justus Winter1-0/+3
* agent/findkey.c (write_extended_private_key): New function. (agent_write_private_key): Detect if an existing file is in extended format and update the key within if it is. (read_key_file): Handle the new format. * agent/keyformat.txt: Document the new format. * common/Makefile.am: Add the new files. * common/private-keys.c: New file. * common/private-keys.h: Likewise. * common/t-private-keys.c: Likewise. * common/util.h (alphap, alnump): New macros. * tests/migrations: Add test demonstrating that we can cope with the new format. -- GnuPG 2.3+ will use a new format to store private keys that is both more flexible and easier to read and edit by human beings. The new format stores name,value-pairs using the common mail and http header convention. This patch adds the parser and support code and prepares GnuPG 2.1 for the new format.

2016-01-19common: Add substitute code for libgpg-error < 1.22.Werner Koch1-2/+4
* common/util.h (GPG_ERR_DB_CORRUPTED): New.

* common/util.h (server_control_s, ctrl_t): Move to ... * common/fwddecl.h: New file. * common/call-gpg.h: Replace typedef by fwddecl.h. Change include protection macro name. * common/Makefile.am (common_sources): Add fwddecl.h. -- It seems some compilers do not grok a re-declaration. Thus we factor it out into a separate file and use the include protection macro to protect against re-declaration. GnuPG-bug-id: 2200 Signed-off-by: Werner Koch <[email protected]>
