Ayy looks like #gpg borked in #Devuan unstable (silently, too. No apt warnings). I now can't validate the signatures of the packages anymore which means apt upgrade stopped working. Oops? :devuannew: :blobfoxpat:

... and naturally, the apparent fix is being held back by apt: gpg, gpg-wks, etc all not upgradeable because of uncheckable signatures. :blobcattableflip:

Is there a way to force this upgrade, ignore signature and such?

tallship, to privacy

#e2ee is a goal, not a promise. As far back as I can remember, forums like those supporting #Enigmail and #gpg were staffed with volunteers from the privacy community who repeatedly insisted on answering questions, like, "Is <this> (whatever this might be) totally secure?" with stock questions like, "What is it that you consider 'totally secure?" or answers such as, "Secure is a relative term, nothing is completely secure, how secure do you need your mission's communications to be?"

Phrases such as, reasonably secure should be indicators of how ridiculous it is to assume that any secure platform is EVER completely, and totally secure.

That begs the question, "Exactly how secure do you require your communications to be?" The answer is always, ... relative.

Which means that you should always believe Ellen Ripley when she says, "Be afraid. Be very afraid!"

mikedev,

My experience is that state actors won't even try to decrypt your communications. That's old school - and a horribly inefficient use of resources. They'll come after you with a keylogger or manufactured legal nightmares or torture - to either or both sides of the communication; depending on the perceived value of your secret.

It all comes down to 4 fundamental questions:

  • What is the value of your secret to you
  • What resources do you have available to protect it
  • What is the perceived value of your secret to your adversary
  • What resources do they have available to divulge it

Meet oct-git, a new #OpenPGP signing and verification tool for use with the #Git distributed version control system:

https://crates.io/crates/openpgp-card-tool-git 🦀

oct-git focuses exclusively on ergonomic use with OpenPGP card-based signing keys

It is designed to be easy to set up, standalone (no long running processes), and entirely hands-off to use (no repeated PIN entry required, by default). It comes with desktop notifications for touch confirmation (if required)

#RustLang #PGP #GnuPG #gpg #Nitrokey #YubiKey

oct-git is joint work with the always excellent @wiktor

Thanks to NLNet and @NGIZero for funding work on this project!

I just released version 0.3.1 of https://crates.io/crates/rsop, a stateless ("sop") card tool based on .
rsop natively supports OpenPGP card (hardware cryptography) devices

SOP is a standardized, vendor agnostic, CLI interface for the most common OpenPGP operations.
See https://datatracker.ietf.org/doc/draft-dkg-openpgp-stateless-cli/ for more on SOP.

rsop is featured in the "OpenPGP interoperability test suite" at https://tests.sequoia-pgp.org/ (under "rpgpie", which is rsop's high level OpenPGP library).

Much credit and thanks to @wiktor for foundational work on OpenPGP card support in .

Wiktor's work constitutes the core of the new https://crates.io/crates/openpgp-card-rpgp crate (used in rsop).

I have upgraded two systems to #Ubuntu 24.04 now and also tried #Thunderbird as snap (which is the default for Ubuntu 24.04) on another machine.

The system upgrades were incredibly smooth. Thunderbird in general also works fine, but it doesn't support #GPG with private keys on a #YubiKey yet (which is my usecase). (Yes,there is a workaround, although clunky.)

So it looks like I'll stay on 23.10 a bit longer on my main machine.

@oliklee Me too but I don’t understand why there are so many different competing package formats once again. And then there is the whole nix universe as well. Hard to decide what to use and tbh, double click an exe or moving a dmg file is sometimes easier than using a package manager. 🫣

I spent a lot of time today trying to figure out / to encrypt and sign backups. I've used it occasionally for literally decades, but still struggle with it. I know if I used it more, I would get used to it and feel more comfortable, but I don't have the time or the need to use it more.

Is there another good open source program to symmetrically encrypt a file? But, for signing, you would still need to use key pairs, right?

Any good how-tos out there?

My first troublesome hallucination with a in a while: (200k context) insisting that I can configure my existing keys to work with PKINIT with and helping me for a couple of hours to try to do so — before realising that GPG keys aren't supported for this use case. Whoops.

No real bother other than some wasted time, but a bit painful and disappointing.

Now to start looking at PIV instead.

I just released version 0.10.1 of https://crates.io/crates/openpgp-card-tools, the general purpose "oct" card tool.

This release adds the "oct admin signing-pin-validity" subcommand, to configure if a card requires User PIN presentation for each signature operation, or if User PIN presentation is valid for the full duration of a connection to the card.

( calls this flag "forcesig")

hko, (edited )
@hko@fosstodon.org avatar

FWIW, I am skeptical of the usefulness of "per-signature PIN presentation" on modern OpenPGP card devices.

This mode made sense with actual Smart Cards, when used in a reader with a physical pin pad.

However, with modern USB devices, I'd say that "touch confirmation" serves a similar goal, but is more fit for purpose.

Mechanisms that move authorization for signing operations outside the host computer add some defense in depth. Repeated PIN presentation from the host computer, less so.

@protonprivacy @blueghost (can be) true, buuut, theres one thing wich mess people up - many takes writing from/to proton mail users as something wich will be encrypted "by default" without any knowledge of how pgp keys works + it just about trust that proton does not read messages when storing secret key themselves...

@iuvi @blueghost Note that Proton Mail servers don't hold your private master key directly — it is always stored encrypted with your account password. And we don't have access to your account password.

Use a GPG smartcard with Thunderbird. Part 1: setup GnuPG

https://stafwag.github.io/blog/blog/2024/04/21/use-a-gpg-smartcard-with-thunderbird-part_1-setup-gpg/

I moved to a Thinkpad w541 with coreboot so I needed to set up my email encryption on Thunderbird again.

It took me more time to reconfigure it again - as usual - so I decided to take notes this time and create a blog post about it. As this might be useful for somebody else … or me in the future :-)

@adamsdesk For the fsf europe fellowship card I don't know. I got my card 8 year ago from floss-shop.de. (I live in Europe/Belgium BTW ) You can check with them if they ship to Canada.

But the setup should work with any GPG compatible smartcard. I'm also looking at Not sure if nitrokey is available on your side of the ocean 🙂

is also a option:
https://stafwag.github.io/blog/blog/2015/06/16/using-yubikey-neo-as-gpg-smartcard-for-ssh-authentication/

But I lean more to nitrokey as I have the impression that they're more active in the opensource community

The new "Simple standalone Agent for cards" (https://crates.io/crates/openpgp-card-ssh-agent) is now available as a package for Linux, by the way :arch: 😏

This agent offers a frictionless UX when using ssh with keys that are stored on OpenPGP card devices: No more ongoing PIN entry required! 🚀

@dvzrv has once again done amazing packaging and documentation work! 🥳 Thank you 😃

See https://wiki.archlinux.org/title/SSH_keys#OpenPGP_card_ssh-agent for details.
