The 2.2 branch has been classified as an old stable branch, which will be supported until the end of 2024. The GnuPG 1.4 branch continues to be maintained as a classic series, consuming minimal resources, suitable for embedded systems and compatible with outdated encryption algorithms.         <\/p>\n<p>Key changes in GnuPG 2.4 compared to the previous stable branch 2.2:  <\/p>\n<ul>\n<li class=\"l\"> A background process has been added with a key database implementation using SQLite for storage, demonstrating significantly faster key searches. To enable the new storage, the 'use-keyboxd' option should be activated in common.conf.\n<li class=\"l\"> A new background process, tpm2d, has been added, allowing the use of TPM 2.0 chips to protect private keys and perform encryption or digital signature operations on the TPM module side.\n<li class=\"l\"> A new utility gpg-card has been added, which can be used as a flexible interface for all supported types of smart cards.\n<li class=\"l\"> A new utility gpg-auth for authentication has been added.\n<li class=\"l\"> A new shared configuration file common.conf has been introduced, which is used to enable the keyboxd background process without separately adding settings in gpg.conf and gpgsm.conf.    <\/li>\n<li class=\"l\"> Support for the fifth version of keys and digital signatures has been provided, which uses the SHA256 algorithm instead of SHA1.  <\/li>\n<li class=\"l\"> The default algorithms for public keys are now ed25519 and cv25519.  <\/li>\n<li class=\"l\"> Support for AEAD modes of block encryption OCB and EAX has been added.\n<li class=\"l\"> Support for elliptic curves X448 (ed448, cv448) has been added.\n<li class=\"l\"> The use of group names in key lists is now allowed.\n<li class=\"l\"> In gpg, gpgsm, gpgconf, gpg-card, and gpg-connect-agent, the '--chuid' option has been added for changing the user identifier.\n<li class=\"l\"> Full Unicode support in the command line has been implemented on the Windows platform.\n<li class=\"l\"> A build option '--with-tss' has been added to select the TSS library.    <\/li>\n<li class=\"l\"> Basic ECC support and the ability to create EdDSA certificates have been added to gpgsm. Support for decrypting data encrypted with a password has been included. AES-GCM decryption support has been added. New options '--ldapserver' and '--show-certs' have been introduced.    <\/li>\n<li class=\"l\"> In the agent, using the value 'Label:' in the key file for configuring PIN input prompts is now permitted. Support for ssh-agent extensions for environment variables has been implemented. Win32-OpenSSH emulation via gpg-agent has been added. By default, the SHA-256 algorithm is used to create fingerprints for SSH keys. Options '--pinentry-formatted-passphrase' and '--check-sym-passphrase-pattern' have been added.    <\/li>\n<li class=\"l\"> In scd, support for working with multiple card readers and tokens has been enhanced. The ability to use multiple applications with a specific smart card has been implemented. Support for PIV cards, Telesec Signature Cards v2.0, and Rohde&amp;Schwarz Cybersecurity has been added. New options '--application-priority' and '--pcsc-shared' have been introduced.\n<li class=\"l\"> The gpgconf utility has added the '--show-configs' option.\n<li class=\"l\"> Changes in gpg:\n<ul>\n<li class=\"l\"> A parameter '--list-filter' has been added for selective key listing, for example 'gpg -k --list-filter 'select=revoked-f &amp;&amp; sub\/algostr=ed25519'.\n<li class=\"l\"> New commands and options have been added: '--quick-update-pref', 'show-pref', 'show-pref-verbose', '--export-filter export-revocs', '--full-timestrings', '--min-rsa-length', '--forbid-gen-key', '--override-compliance-check', '--force-sign-key', and '--no-auto-trust-new-key'.\n<li class=\"l\"> Support for importing arbitrary lists of revoked certificates has been added.\n<li class=\"l\"> Verification of digital signatures has been accelerated by more than ten times.\n<li class=\"l\">  Verification results now depend on the '--sender' option and the signature creator's identifier.\n<li class=\"l\"> The ability to export Ed448 keys for SSH has been added.\n<li class=\"l\"> Only OCB mode is allowed for AEAD encryption.\n<li class=\"l\"> Decryption without a public key is permitted if a smart card is inserted.\n<li class=\"l\"> For the algorithms ed448 and cv448, the creation of fifth-generation keys is now forcefully enabled.\n<li class=\"l\"> When importing from <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/en\/server\/dts-los-angeles\/\"   title=\"server\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"3882\">server<\/a> LDAP, applying the self-sigs-only option is disabled by default.  <\/ul>\n<\/li>\n<li class=\"l\"> In gpg, the use of algorithms with a block size of 64 bits for encryption has been discontinued. 3DES usage is prohibited, and AES is declared as the minimally supported algorithm. The '--allow-old-cipher-algos' option can be used to disable this restriction.  <\/li>\n<li class=\"l\"> The symcryptrun utility (an outdated wrapper around the external tool Chiasmus) has been removed.  <\/li>\n<li class=\"l\"> Support for the deprecated PKA key discovery method has been discontinued, and associated options have been removed.          <\/ul>\n<p>Source: <a content=\"nofollow\" rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=58365\">opennet.ru<\/a> <\/p>","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"excerpt":{"rendered":"<p>\u041f\u043e\u0441\u043b\u0435 \u043f\u044f\u0442\u0438 \u043b\u0435\u0442 \u0440\u0430\u0437\u0440\u0430\u0431\u043e\u0442\u043a\u0438 \u043f\u0440\u0435\u0434\u0441\u0442\u0430\u0432\u043b\u0435\u043d \u0440\u0435\u043b\u0438\u0437 \u0438\u043d\u0441\u0442\u0440\u0443\u043c\u0435\u043d\u0442\u0430\u0440\u0438\u044f GnuPG 2.4.0 (GNU Privacy Guard), \u0441\u043e\u0432\u043c\u0435\u0441\u0442\u0438\u043c\u043e\u0433\u043e \u0441\u043e \u0441\u0442\u0430\u043d\u0434\u0430\u0440\u0442\u0430\u043c\u0438 OpenPGP (RFC-4880) \u0438 S\/MIME, \u0438 \u043f\u0440\u0435\u0434\u043e\u0441\u0442\u0430\u0432\u043b\u044f\u044e\u0449\u0435\u0433\u043e \u0443\u0442\u0438\u043b\u0438\u0442\u044b \u0434\u043b\u044f \u0448\u0438\u0444\u0440\u043e\u0432\u0430\u043d\u0438\u044f \u0434\u0430\u043d\u043d\u044b\u0445, \u0440\u0430\u0431\u043e\u0442\u044b \u0441 \u044d\u043b\u0435\u043a\u0442\u0440\u043e\u043d\u043d\u044b\u043c\u0438 \u043f\u043e\u0434\u043f\u0438\u0441\u044f\u043c\u0438, \u0443\u043f\u0440\u0430\u0432\u043b\u0435\u043d\u0438\u044f \u043a\u043b\u044e\u0447\u0430\u043c\u0438 \u0438 \u0434\u043e\u0441\u0442\u0443\u043f\u0430 \u043a \u043f\u0443\u0431\u043b\u0438\u0447\u043d\u044b\u043c \u0445\u0440\u0430\u043d\u0438\u043b\u0438\u0449\u0430\u043c \u043a\u043b\u044e\u0447\u0435\u0439.
