I just released version 0.1.3 of rsop-oct, a stateless #OpenPGP ("SOP") CLI tool for use with OpenPGP card hardware devices:

crates.io/crates/rsop-oct/

Like its sibling project #rsop, rsop-oct is based on @rpgp

This update adds support for the SOP command 'certify-userid'.

This allows issuing certifications (aka "third-party signatures") over identities in other people's OpenPGP certificates, directly with an OpenPGP card device.

For more on #SOP, see datatracker.ietf.org/doc/draft

Oh and with #encryption I mean the gritty #DIY stuff. So don’t rely on the encrypted backup option baked in your favorite app or (mobile) OS.

If you don’t own it, you are being owned.

#GPG (or #GnuPG) using elliptic curve factorization is your friend!

In the (hopefully near) future post-quantum encryption #pqe will be available in some form. Although this tech was anticipated to arrive years ago… so what’s keeping it.

I just learned that when encrypting email with PGP, the subject line of the email is NOT encrypted. Two things about this fascinate me:

- what a glaring oversight. How did anyone ever think that not encrypting the subject line was a good idea

- why is this not more commonly known? i feel like every guide how to use PGP for email should be screaming from the rooftops: "TAKE NOTE THAT THE SUBJECT LINE OF YOUR EMAILS IS NOT ENCRYPTED". Instead, I just found it deep in the details of one such guide. Many guides (yes I checked several) don't include this information at all.

@mailbox_org Sehr schön, dass Ihr OpenPGP weiterhin unterstützt.

Es ist eine der wenigen dezentralen und mit OpenPGPv4 gut standardisierten Möglichkeiten, sich vertraulich auszutauschen.

Ein Hinweis: Wer Eure severseitige Lösung verwendet hat vermutlich keine Ende-zu-Ende Verschlüsselung mehr, weil er der Software auf Eurem Server vertrauen muss.

Wie steht es eigentlich mit der Unterstützung von modernem Web Key Directory?

#GnuPG
(Zur Info: Bin mehr als 20 Jahre bei #GnuPG dabei.)

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

lists.gnupg.org/pipermail/gnup

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.

Technical details: dev.gnupg.org/T7671

lists.gnupg.org[Announce] GnuPG 2.5.7 released

I just released version 0.1.2 of rsop-oct, a stateless #OpenPGP ("SOP") CLI tool for use with OpenPGP card hardware devices:

crates.io/crates/rsop-oct/

Like its sibling project #rsop, rsop-oct is based on @rpgp

This update makes integration with crates.io/crates/openpgp-card- optional.

rsop-oct can now implicitly use persisted PINs via openpgp-card-state, or explicitly provided ones via the standard SOP CLI parameter '--with-key-password'.

For more on #SOP, see datatracker.ietf.org/doc/draft

If you are using the PDF viewer #Okular_from #Gpg4win, please upgrade to version 4.4.1 as this version fixes a severe vulnerability in the freetype library.

:download: gpg4win.org/download.html

Vulnerability details:
euvd.enisa.europa.eu/enisa/EUV 🛡️

There are other good things in Gpg4win 4.4.1, for example
* improvements in the Outlook Add-in (GpgOL)
* a better Kleopatra
* GnuPG upgraded to v2.4.8

www.gpg4win.orgGpg4win - Download Gpg4win

Neue Version von #GnuPG (v2.5.6) und eine weitere Beta-Version des kommenden #Gpg4Win 5.0 erschienen.

Wer Gpg4Win (noch) nicht kennt: Enthält u.a. das MS Outlook-Plugin GpgOL damit dort #OpenPGP-verschlüsselte Mails funktionieren, GpgEX damit man im Explorer Dateien verschlüsseln kann, oder die Schlüssel-/Zertifikats-Verwaltung Kleopatra. Mit 5.0 dann Post Quanten resistant encryption.

S/MIME gibt es natürlich auch. Das skaliert wegen der Kosten für die zusätzlich zeitlimitierten Zertifikate, in der Bevölkerung aber noch schlechter als OpenPGP. Deshalb plädiere ich für einen Fokus darauf um wenigstens hier eine größere Verbreitung zu schaffen.

Und von mir ein fettes Danke an den Hauptentwickler der Werkzeuge @DD9JN
