Tracking BitCoin "Q-Day".

Researcher cracks 15-bit elliptic curve key, aka an Elliptic Curve Cryptography (ECC) Key using public quantum hardware and is awarded the “Q-Day Prize bounty" of 1 BTC.

BitCoin and Ethereum utilize ECC - the larger 256 bit key - specifically the secp256k1 curve, for securing wallets and transactions. https://decrypt.co/365444/bitcoin-q-day-draws-nearer-quantum-researcher-breaks-simplified-key #Bitcoin #Cryptography #Ethereum #Crypto #CryptoCurrencies #Encryption #Security #ECC #EllipticCurve #QDay #DigitalSignature #BlockChain #QuantumComputing #Quantum #BTC

Please help with testing a new
#Thunderbird #Security feature: Unobtrusive Signatures, a novel mechanism for digitally signing email, currently implemented for #OpenPGP.

It avoids the unexpected signature attachments that are shown by non-supporting email clients for emails that used the traditional signing format, and that were frequently confusing recipients. With this new mechanism, it should be fine to sign all emails.

More details here:

The #blog post "Verify Arch Linux artifacts using VOA/OpenPGP" has been published:

https://devblog.archlinux.page/2026/verify-arch-linux-artifacts-using-voa-openpgp/

#ArchLinux #SovereignTechFund #STF #devblog #OpenPGP #RustLang #DigitalSignature #Verification #VOA

Together with @hko I have worked on the "File Hierarchy for the Verification of OS Artifacts" (#VOA) in 2024 and 2025.

This #STF ( @sovtechfund ) funded #specification and #ReferenceImplementation (🦀) enables technology and distribution agnostic verification of OS artifacts.

In this #blog post we are looking into the #verification of #ArchLinux artifacts, using the `voa` #CLI and its #OpenPGP backend:

Together with @hko @j-g00da, @orhun and @Nukesor I have been working on the #ALPM and #VOA projects in 2024 and 2025.

This #SovereignTechFund ( @sovtechfund ) funded work has recently come to a close.

You can read all about what was achieved and plans for future work on the #ArchLinux #devblog: https://devblog.archlinux.page/2026/a-year-of-work-on-the-alpm-project/

A new version of the #VOA #CLI and #library is out! 🎉 🦀 📦⌨️

https://crates.io/crates/voa/0.2.0

In this version we add the `voa list` and `voa verify` subcommands for listing of verifiers and verification of #OS #artifacts.

With it, we introduced experimental #OpenPGP support.

A new version of the #OpenPGP backend for #VOA is out. 🎉 🦀 📦

https://crates.io/crates/voa-openpgp/0.2.0

In version 0.2.0 we have added the first experimental support for the verification of #OS artifacts.

#RustLang #DigitalSignature #Signature #Verification #Packaging

We have just released version 0.3.0 of the #VOA core library. 🥳 🦀 📦

https://crates.io/crates/voa-core/0.3.0

In this release we have reduced the use of runtime dependencies and started exposing more functionality for consumers of this library.

#DigitalSignature #RustLang #Signing #Signature #Verification #OpenPGP

Today we released the first version of the #VOA library and #CLI. 🥳 🦀 📦⌨️

https://crates.io/crates/voa/0.1.0

This initial version is only able to import cryptographic verifiers for now.

In an upcoming version we plan to provide the first, simple #OpenPGP #signature #verification support. 🔏

#DigitalSignature #RustLang #Signing #Packaging

Today we have also created the first release of voa-openpgp, a #RustLang library for the use of #OpenPGP verifiers in #VOA hierarchies. 📦 🦀

https://crates.io/crates/voa-openpgp/0.1.0

In this first release we have focused on the use case of importing #OpenPGP certificates to a #VOA hierarchy.

As a special treat, this enables direct import of #ArchLinux keyring structures.

Many thanks to @hko @Nukesor and @orhun for the thorough reviews 🎉

Version 0.2.0 of voa-core, a #RustLang library for access to verifiers in #VOA hierarchies has just been released. 🦀 🥳

https://crates.io/crates/voa-core/0.2.0

In this version we have improved our handling of identifiers with the help of #winnow parsers.
In addition we have added a #trait for generic writing of verifiers to VOA hierarchies.

See the #changelog for further information:

We have just released the first version of voa-core, a #RustLang library for access to verifiers in #VOA structures. 🎁 🦀

https://crates.io/crates/voa-core/0.1.0

VOA, short for "File Hierarchy for the Verification of OS Artifacts", is a way of providing and using verifiers for digital signatures in a stateless manner, for various cryptographic technologies:

With the release of `nethsm-cli` 0.6.0 it is now possible to issue signatures for signing requests! 🎉 📦 🦀

https://crates.io/crates/nethsm-cli/0.6.0

Signing requests for files can be created using `signstar-request-signature` (see https://chaos.social/@dvzrv/113646761365294969).
