#endtoendcrypto — Public Fediverse posts

When looking at the changes towards the new 2.5.19 version of #GnuPG, there are many small things; like a way to use OCB for symmetric-only encryption, a few defect fixes and improvements.

Not that exciting, but maintenance of the well known #LibrePGP, OpenPGPv4 and CMS capable crypto engine.... you may want to know anyhow. ;)

Dear GnuPG packagers and builders, please upgrade libgcrypt to v1.12.2 to remove a denial of service vulnerability (estimated CVSS 3.1: AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H -- 7.5 (HIGH)) Releases of other stable versions of libgcrypt are available as well.

(GnuPG versions >= 2.5.7 are not affected due to the use of a different encryption API.)

See https://lists.gnupg.org/pipermail/gnupg-announce/2026q2/000503.html for details.

Details about the (ongoing) response to https://gpg.fail/ from GnuPG's side:

* https://dev.gnupg.org/T7906 Memory Corruption in ASCII-Armor Parsing
* https://dev.gnupg.org/T7900 (overview)

Please upgrade to GnuPG 2.5.16, 2.4.9 or #Gpg4win 5.0.0-beta479 which already have the fix for what (currently) is seen to be the only major defect: T7906.

(Researchers - Thanks! - found defects in GnuPG, Sequoia-PG, Minisign and age.)

#GnuPG v2.5.14 is here to try.

A no-brainer upgrade for those who use the 2.5 series already. You'd get some defects fixed and a new secret key export-import for the Post quantum cryptography (#PQC) algorithm "Kyber". RCF8332 for ssh is now supported.

For others: the 2.5 series is good for Windows 64 and PQC. #LibrePGP #OpenPGPv4 #EndtoEndCrypto

@fdroidorg @Tutanota the original claim was protecting data and notification patterns. So that Google and Apple cannot see them. IMAPS and SMTPS is enough for this, only the network operators and the server operators can then see notifications and the data.

If you want to do more, a standardized #endtoendcrypto solution for email is a good next step. Coming with some work. Like using OpenPGPv4/MIME (or LibrePGP/MIME, S/MIME). That protects even against the server provider to some extend.

@DD9JN ... and #GnuPG v2.5.13 is a production ready version with improvements for PQC encryption and Windows.

This version comes with a few smaller security improvements over the previous release, and reduces problems if several applications use GnuPG as crypto engine in the background.

Back from the summer, #GnuPG 2.5.12 is now ready for production usage.
And this includes the post-quantum cryptography encryption (#PQC) support which is the main feature of the 2.5 series. (Okay, there is also better support for 64bit Windows.)

So give it a spin or point your favourite GNU/Linux distribution to it for packaging.

#GnuPG's "public testing release series" has a new version 2.5.7.

https://lists.gnupg.org/pipermail/gnupg-announce/2025q2/000493.html

Remember:

* It is for you, if you want to test the new
post-quantum cryptography (PQC) features
or the 64 Bit Windows support.

* The series features Kyber (FIPS-203) as PQC encryption algorithm.

A new Gpg4win 5 Beta is forthcoming in the next days.

#GnuPG 2.4.5 comes with a number of improvements,
that look small at first sight, but can be decisive
if you have the use case. Like one additional NFC reader (ACR-122U)

from behind a proxy is fixed. Details: https://dev.gnupg.org/T6960

#Gpg4win v4.3.0 <- freshly announced.

New is that encrypted files with email structure from disk can be shown.

Kleopatra and the Outlook Add-in gain features and resilience for less common situations (like Apple mail attachments or unreliable S/MIME CRLs).

Includes #GnuPG v2.4.4 and its many improvements.

Look at https://gpg4win.org/version4.2.html to see why freshly released #Gpg4win 4.2.0 makes a difference: Includes an experimental, lightweight PDF reader geared towards secure environments.(To use the validation and signing abilities of the included PDF Reader #Okular by #KDE today, you'd probably need to be an expert to configure the certs. Usability is planned to improve with later releases). Gpg4win is faster for large files and with many public keys. #GnuPG 2.4.3 included. #EndtoEndCrypto #OpenPGP

Looking into #GnuPG 2.4.3, which is available now: It is a typical small point release which fixes some minor defects and improves the performance on Windows, especially for for large files.

Noteworthy also: the default expiration time period for new public keys has been increased to 3 years and that there is a new PKCS#12 parser (yes GnuPG's gpgsm can do CMS for S/MiME ;) ).

@fsf Thanks for promoting a decentral comunication solution - email and OpenPGP with GnuPG! As for the guide,: keyservers and the web of trust have lost quite a bit of relevance in recent years. What would be really cool is to select an email provider that offers the pubkeys via the web key directory. https://wiki.gnupg.org/WKD and bring your public key up there. #GnuPG #FreeSoftware #EndtoEndCrypto

#GnuPG 2.2.33 LTS brings a

#GnuPG 2.2.32 (LTS) fixes an important piece of validation when using keyservers or WKD with websites that use Let's encrypt certificates. Either go to GnuPG 2.2.32 or remove an outdated intermediate certificate from Let's encrypt from your system cert store.
