* sm: Allow decryption using dhSinglePass-stdDH-sha1kdf-scheme.Werner Koch2020-05-081-32/+68
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * sm/decrypt.c (ecdh_decrypt): Support dhSinglePass-stdDH-sha1kdf-scheme. Factor key derive code out to ... (ecdh_derive_kek): new global function. Allow for hashs shorter than the key. (hash_ecc_cms_shared_info): Make file-only. * sm/encrypt.c (ecdh_encrypt): Replace derive code by a call to the new ecdh_derive_kek. Add test code to create data using dhSinglePass-stdDH-sha1kdf-scheme. * sm/gpgsm.h (opt): Add member force_ecdh_sha1kdf. * sm/gpgsm.c: Add option --debug-force-ecdh-sha1kdf. -- I did some test against Governikus_Signer: 2.9.2.0 MCard security Provider: 2.4.0 Algorithm catalog from: 05.12.2019 using a Signature Card v2.0 and a nistp256 certificate. Encrypting with Governikus used the stdDH-sha1kdf scheme which we can now decrypt. Encrypting with GPGSM uses for that curve the recommended scheme sha256kdf but Governikus was not able to decrypt this (no usable error message). Encrypting using stdDH-sha1kdf with GPGSM by using the new --debug-force-ecdh-sha1kdf option showed that Governikus was able to decrypt this. FWIW: RFC5753 (Use of Elliptic Curve Cryptography (ECC) Algorithms) has this requirement: Implementations that support EnvelopedData with the ephemeral-static ECDH standard primitive: - MUST support the dhSinglePass-stdDH-sha256kdf-scheme key agreement algorithm, the id-aes128-wrap key wrap algorithm, and the id-aes128-cbc content encryption algorithm; and which Governikus seems not to fulfill.

* Use the gpgrt log functions if possible.Werner Koch2017-11-271-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | * common/logging.c: Do not build any code if we can use the gpgrt_log functions. (log_logv_with_prefix): Rename to log_logv_prefix and change order of args so that this function matches its printf like counterpart gpgrt_logv_prefix. Change all callers. (log_debug_with_string): Rename to log_debug_string. Change all callers. (log_printhex): Move first arg to end so that this function matches its printf like counterpart gpgrt_log_printhex. Change all callers. * common/logging.h: Divert to gpgrt/libgpg-error if we can use the gpgrt_log functions. (bug_at): Add inline versions if we can use the gpgrt_log functions. * configure.ac (GPGRT_ENABLE_LOG_MACROS): Add to AH_BOTTOM. (mycflags): Add -Wno-format-zero-length. -- This patch enables the use of the log function from libgpgrt (aka libgpg-error). Instead of checking a version number, we enable them depending on macros set by recent gpg-error versions. Eventually the whole divert stuff can be removed. The -Wno-format-zero-length is required because log_printhex can be called with an empty format string. Note that this is fully specified standard C behaviour.

* gpg,sm: Error out on compliance mismatch while decrypting.Werner Koch2017-08-011-7/+12
| | | | | | | | | | | | | | | | | | | | * g10/pubkey-enc.c (get_session_key): Bail out if the algo is not allowed in the current compliance mode. * sm/decrypt.c (gpgsm_decrypt): Ditto. -- The idea here is that the owner of the key created a non-compliant key and later receives a mail encrypted to that key. The sender should have checked this key too but we can't guarantee that. By hard failing here the owner of the key will notice that he had created a non-compliant key and thus has a chance to generate a new compliant key. In case the compliant criteria changes and the owner wants to decrypt an old message he can still switch gpg to another compliant mode.

* 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.
* Nuked almost all trailing white space.post-nuke-of-trailing-wsWerner Koch2011-02-041-25/+23
| | | | | | | | 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.
