とあるので PGP 30周年記念ということでいいだろう。 ちなみに今回はメンテンナンスのみでセキュリティ・アップデートはない。
詳細はこちら。
- gpg: Auto import keys specified with
--trusted-keys
. [e7251be84c79]- gpg: Allow decryption w/o public key but with correct card inserted. [e53f6037283e]
- gpg: Allow fingerprint based lookup with
--locate-external-key
. [2af217ecd7e4]- gpg: Lookup a missing public key of the current card via LDAP. [b59af0e2a05a]
- gpg: New option
--force-sign-key
. [#4584]- gpg: Use a more descriptive password prompt for symmetric decryption. [03f83bcda5d1]
- gpg: Do not use the
self-sigs-only
option for LDAP keyserver imports. [#5387]- gpg: Keep temp files when opening images via xdg-open. [0441ed6e1c]
- gpg: Fix mailbox based search via AKL keyserver method. [22fe23f46d31]
- gpg: Fix sending an OpenPGP key with umlaut to an LDAP keyserver. [7bf8530e75d0]
- gpg: Allow ECDH with a smartcard returning only the x-coordinate. [b203325ce1]
- gpgsm: New option
--ldapserver
as an alias for--keyserver
. Note that configuring servers in gpgsm and gpg is deprecated; please use the dirmngr configuration options.- gpgsm: Support AES-GCM decryption. [b722fd755c77]
- gpgsm: Support decryption of password protected files. [6f31acac767f]
- gpgsm: Lock keyboxes also during a search to fix lockups on Windows. [#4505]
- agent: Skip unknown unknown ssh curves seen on cards. [bbf4bd3bfcb5]
- scdaemon: New option
--pcsc-shared
. [5eec40f3d827]- scdaemon: Backport PKCS#15 card support from GnuPG 2.3 [7637d39fe20e]
- scdaemon: Fix CCID driver for SCM SPR332/SPR532. [#5297]
- scdaemon: Fix possible PC/SC removed card problem. [9d83bfb63968]
- scdaemon: Fix unblock PIN by a Reset Code with KDF. [#5413]
- scdaemon: Support compressed points. [96577e2e46e4]
- scdaemon: Prettify S/N for Yubikeys and fix reading for early Yubikey 5 tokens. [f8588369bcb0,#5442]
- dirmngr: New option
--ldapserver
to avoid the need for the separatedirmngr_ldapservers.conf
file.- dirmngr: The dirmngr_ldap wrapper has been rewritten to properly support ldap-over-tls and starttls for X.509 certificates and CRLs. [39815c023f03]
- dirmngr: OpenPGP LDAP keyservers may now also be configured using the same syntax as used for X.509 and CRL LDAP servers. This avoids the former cumbersome quoting rules and adds a flexible set of flags to control the connection. [2b4cddf9086f]
- dirmngr: The “ldaps” scheme of an OpenPGP keyserver URL is now interpreted as ldap-with-starttls on port 389. To use the non-standardized ldap-over-tls the new LDAP configuration method of the new attribute “gpgNtds” needs to be used. [55f46b33df08]
- dirmngr: Return the fingerprint as search result also for LDAP OpenPGP keyservers. This requires the modernized LDAP schema. [#5441]
- dirmngr: An OpenPGP LDAP search by a mailbox now ignores revoked keys. [b6f8cd7eef4b]
- gpgconf: Make runtime changes with non-default homedir work. [c8f0b02936c7]

- Full Unicode support for the Windows command line. [#4398]
- Fix problem with Windows Job objects and auto start of our daemons. [#4333]
- i18n: In German always use “Passwort” instead of “Passphrase” in prompts.
Release-info: https://dev.gnupg.org/T5482
現在 GnuPG には2.2系と2.3系があり,2.2系は LTS 版に位置づけられている。 2.3系では AEAD (Authenticated Encryption with Associated Data) 等 RFC 4880bis で検討されている機能が実装されているので,最新機能を試したいのであればこちらを入れるとよいだろう。 通常運用であれば2.2系で問題ない(ECC も対応してるよ)。

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。
