GnuPG 2.1.18 がリリース

no extension

GnuPG 2.1.18 がリリースされている。

今回もセキュリティ・アップデートはなし。 主な修正点は以下の通り。

  • gpg: Remove bogus subkey signature while cleaning a key (with export-clean, import-clean, or --edit-key’s sub-command clean)
  • gpg: Allow freezing the clock with --faked-system-time.
  • gpg: New --export-option flag “backup”, new --import-option flag “restore”.
  • gpg-agent: Fixed long delay due to a regression in the progress callback code.
  • scd: Lots of code cleanup and internal changes.
  • scd: Improved the internal CCID driver.
  • dirmngr: Fixed problem with the DNS glue code (removal of the trailing dot in domain names).
  • dirmngr: Make sure that Tor is actually enabled after changing the conf file and sending SIGHUP or “gpgconf --reload dirmngr”.
  • dirmngr: Fixed Tor access to IPv6 addresses. Note that current versions of Tor may require that the flag “IPv6Traffic” is used with the option “SocksPort” in torrc to actually allow IPv6 traffic.
  • dirmngr: Fixed HKP for literally given IPv6 addresses.
  • dirmngr: Enabled reverse DNS lookups via Tor.
  • dirmngr: Added experimental SRV record lookup for WKD. See commit 88dc3af3d4ae1afe1d5e136bc4c38bc4e7d4cd10 for details.
  • dirmngr: For HKP use “pgpkey-hkps” and “pgpkey-hkp” in SRV record lookups. Avoid SRV record lookup when a port is explicitly specified. This fixes a regression from the 1.4 and 2.0 behavior.
  • dirmngr: Gracefully handle a missing /etc/nsswitch.conf. Ignore negation terms (e.g. “[!UNAVAIL=return]” instead of bailing out.
  • dirmngr: Better debug output for flags “dns” and “network”.
  • dirmngr: On reload mark all known HKP servers alive.
  • gpgconf: Allow keyword “all” for --launch, --kill, and --reload.
  • tools: gpg-wks-client now ignores a missing policy file on the server.
  • Avoid unnecessary ambiguity error message in the option parsing.
  • Further improvements of the regression test suite.
  • Fixed building with --disable-libdns configure option.
  • Fixed a crash running the tests on 32 bit architectures.
  • Fixed spurious failures on BSD system in the spawn functions. This affected for example gpg-wks-client and gpgconf.

んー。 IPv6 や Tor 周りが改善されてるって感じ？

SHA-3 や Bitcoin/Blockchain など新しい知見や技術要素を大幅追加。暗号技術を使うだけならこれ1冊でとりあえず無問題。
