sequoia-wot 0.7.0
by Neal H. Walfield 24 Mar '23

24 Mar '23

Hi everyone, I'm pleased to announce the release of version 0.7.0 of the Sequoia Web of Trust crate, sequoia-wot. I have published sequoia-wot on crates.io: https://crates.io/crates/sequoia-wot You can also fetch version 0.7.0 using the v0.7.0 tag: https://gitlab.com/sequoia-pgp/sequoia-wot/-/tags/v0.7.0 which I signed: $ git verify-tag v0.7.0 gpg: Signature made Fri Mar 24 11:31:41 2023 +01:00 gpg: using RSA key C03FA6411B03AE12576461187223B56678E02528 gpg: Good signature from "Neal H. Walfield <neal(a)walfield.org>" [ultimate] gpg: "Neal H. Walfield <neal(a)gnupg.org>" gpg: "Neal H. Walfield <neal(a)pep-project.org>" gpg: "Neal H. Walfield <neal(a)pep.foundation>" gpg: "Neal H. Walfield <neal(a)sequoia-pgp.org>" This release includes an exciting new feature: the ability to render the output as a graphical network in DOT format. The DOT output can in turn be compiled into an SVG using Graphviz's DOT compiler. This is a great usability improvement. This feature was implemented by David Runge, a new Sequoia contributor. Here's an example of how to use it. David says that he is an Arch Linux developer. We can see what Arch developers have certified a certificate with his email address by running: $ sq-wot --format dot \ --keyring usr/share/pacman/keyrings/archlinux.gpg \ --gossip lookup \ --email dvzrv(a)archlinux.org \ | dot -Tsvg -o /tmp/dvzrv.svg The attached SVG shows the result.

sequoia-net 0.27.0
by Neal H. Walfield 24 Mar '23

24 Mar '23

Hi everyone, I'm pleased to announce the release of version 0.27.0 of sequoia-net, a library for looking up certificates on OpenPGP keyservers, in web key directories (WKDs), and using DANE. I have published sequoia-net on crates.io: https://crates.io/crates/sequoia-net You can also fetch version 0.27.0 using the net/v0.27.0 tag: https://gitlab.com/sequoia-pgp/sequoia/-/tags/net/v0.27.0 which I signed: $ git verify-tag net/v0.27.0 gpg: Signature made Fri Mar 24 10:36:11 2023 +01:00 gpg: using RSA key C03FA6411B03AE12576461187223B56678E02528 gpg: Good signature from "Neal H. Walfield <neal(a)walfield.org>" [ultimate] gpg: "Neal H. Walfield <neal(a)gnupg.org>" gpg: "Neal H. Walfield <neal(a)pep-project.org>" gpg: "Neal H. Walfield <neal(a)pep.foundation>" gpg: "Neal H. Walfield <neal(a)sequoia-pgp.org>" The main change in this release is switching DANE from using ring to OpenSSL. As we already use OpenSSL, this reduces the number of dependencies, and the trusted computing base. Neal on behalf of the whole Sequoia PGP team

sequoia-openpgp 1.14.0
by Neal H. Walfield 23 Mar '23

23 Mar '23

Hi everyone, I'm pleased to announce the release of version 1.14.0 of sequoia-openpgp, our low-level OpenPGP library. I have published sequoia-openpgp on crates.io: https://crates.io/crates/sequoia-openpgp You can also fetch version 1.14.0 using the openpgp/v1.14.0 tag: https://gitlab.com/sequoia-pgp/sequoia/-/tags/openpgp/v1.14.0 which I signed: $ git verify-tag openpgp/v1.14.0 gpg: Signature made Thu Mar 23 15:43:58 2023 +01:00 gpg: using RSA key C03FA6411B03AE12576461187223B56678E02528 gpg: Good signature from "Neal H. Walfield <neal(a)walfield.org>" [ultimate] gpg: "Neal H. Walfield <neal(a)gnupg.org>" gpg: "Neal H. Walfield <neal(a)pep-project.org>" gpg: "Neal H. Walfield <neal(a)pep.foundation>" gpg: "Neal H. Walfield <neal(a)sequoia-pgp.org>" A notable change in this release is support for Botan, a new cryptographic backend: https://botan.randombit.net/ sequoia-openpgp now supports five cryptographic backends: - Nettle - OpenSSL - Botan - Windows CNG (Windows only) - Rust Crypto We also audited our protected memory mechanism, and found that there are several cases where secrets were not cleared when the memory was freed. We created a tool to partially automate searching for these types of leaks. We've fixed the cases that we found. For those interested in the details, please refer to these MRs: https://gitlab.com/sequoia-pgp/sequoia/-/merge_requests/1436/commits https://gitlab.com/sequoia-pgp/sequoia/-/merge_requests/1440/commits This release includes several minor performance improvements. In addition, the following functionality was added: - crypto::mem::Protected::new - crypto::mpi::SecretKeyMaterial::from_bytes - crypto::mpi::SecretKeyMaterial::from_bytes_with_checksum - fmt::hex::Dumper::with_offset - parse::buffered_reader re-export - policy::AsymmetricAlgorithm::BrainpoolP384 - RawCert implements Parse And, the following functions were deprecated: - crypto::mpi::SecretKeyMaterial::parse - crypto::mpi::SecretKeyMaterial::parse_with_checksum Neal on behalf of the whole Sequoia PGP team

sequoia-wot 0.6.0
by Neal H. Walfield 09 Mar '23

09 Mar '23

Hi everyone, I'm pleased to announce the release of version 0.6.0 of the Sequoia Web of Trust crate, sequoia-wot. I have published sequoia-wot on crates.io: https://crates.io/crates/sequoia-wot You can also fetch version 0.6.0 using the v0.6.0 tag: https://gitlab.com/sequoia-pgp/sequoia-wot/-/tags/v0.6.0 which I signed: $ git verify-tag v0.6.0 gpg: Signature made Thu Mar 09 14:39:29 2023 +01:00 gpg: using RSA key C03FA6411B03AE12576461187223B56678E02528 gpg: Good signature from "Neal H. Walfield <neal(a)walfield.org>" [ultimate] gpg: "Neal H. Walfield <neal(a)gnupg.org>" gpg: "Neal H. Walfield <neal(a)pep-project.org>" gpg: "Neal H. Walfield <neal(a)pep.foundation>" gpg: "Neal H. Walfield <neal(a)sequoia-pgp.org>" The most noticeable change in this release is that we switched from providing our own certificate store abstraction to using the one provided by sequoia-cert-store. More information about sequoia-cert-store is available here: https://docs.rs/sequoia-cert-store/0.2.0/sequoia_cert_store/ We also added a wrapper struct so that it is easy to work with a `CertStore`, which is provided by the Certificate Store library, or any other data structure implementing the Store trait. The following code snippet illustrates the idea: use std::borrow::Cow; use sequoia_openpgp as openpgp; use openpgp::cert::CertBuilder; use openpgp::packet::UserID; use openpgp::policy::StandardPolicy; use sequoia_cert_store as cert_store; use cert_store::Store; use cert_store::StoreUpdate; use sequoia_wot as wot; use wot::Network; use wot::Query; use wot::Roots; const P: &StandardPolicy = &StandardPolicy::new(); let mut cert_store = cert_store::CertStore::empty(); cert_store.update(Cow::Owned(alice.clone().into()))?; cert_store.update(Cow::Owned(bob.clone().into()))?; // Build a WoT network. let trust_roots = Roots::from(&[ (alice.fingerprint().into(), wot::FULLY_TRUSTED), ]); let wot_data = wot::store::CertStore::from_backend(&cert_store, P, None); let network = Network::new(&wot_data)?; let q = Query::new(&network, trust_roots.clone()); // Try and authenticate Bob. let paths = q.authenticate( UserID::from("<bob(a)example.org>"), bob.fingerprint(), wot::FULLY_TRUSTED); // Alice, our sole trust root, did not certify Bob so this will fail. assert_eq!(paths.amount(), 0); Since we depend on sequoia-cert-store, we can also remove redundant code, like the keyserver implementation, which sequoia-cert-store also implements.

Sequoia Certificate Store v0.2.0
by Neal H. Walfield 07 Mar '23

07 Mar '23

Hi everyone, I'm pleased to announce the release of version 0.2.0 of the Sequoia Certificate Store crate, sequoia-cert-store. I have published sequoia-cert-store on crates.io: https://crates.io/crates/sequoia-cert-store You can also fetch version 0.2.0 using the v0.2.0 tag: https://gitlab.com/sequoia-pgp/sequoia-cert-store/-/tags/v0.2.0 which I signed: $ git verify-tag v0.2.0 gpg: Signature made Tue Mar 07 17:39:46 2023 +01:00 gpg: using RSA key C03FA6411B03AE12576461187223B56678E02528 gpg: Good signature from "Neal H. Walfield <neal(a)walfield.org>" [ultimate] gpg: "Neal H. Walfield <neal(a)gnupg.org>" gpg: "Neal H. Walfield <neal(a)pep-project.org>" gpg: "Neal H. Walfield <neal(a)pep.foundation>" gpg: "Neal H. Walfield <neal(a)sequoia-pgp.org>" sequoia-cert-store provides a unified, high-level API for different certificate stores via its Store and StoreUpdate traits. This version fixes an issue with `CertStore`'s key server backend: calling `CertStore::add_keyserver` accidentally did not enable key server support. This release also includes several other improvements to the key server backend. A notable improvement is the addition of a generic interface, `store::StatusListener`, which allows a backend to indicate when a certificate look up starts and ends. This is implemented by the key server backend. This allows an application to better show the user that the application is working and not hung when using a key server.

rpm-sequoia 1.3.0
by Neal H. Walfield 06 Mar '23

06 Mar '23

Hi everyone, I'm pleased to announce v1.3.0 of the RPM Sequoia crate. I have published rpm-sequoia on crates.io: https://crates.io/crates/rpm-sequoia You can also fetch version 1.3.0 using the v1.3.0 tag: https://github.com/rpm-software-management/rpm-sequoia/releases/tag/v1.3.0 which I signed: $ git verify-tag v1.3.0 gpg: Signature made Mon Mar 06 16:54:07 2023 +01:00 gpg: using RSA key C03FA6411B03AE12576461187223B56678E02528 gpg: Good signature from "Neal H. Walfield <neal(a)walfield.org>" [ultimate] gpg: "Neal H. Walfield <neal(a)gnupg.org>" gpg: "Neal H. Walfield <neal(a)pep-project.org>" gpg: "Neal H. Walfield <neal(a)pep.foundation>" gpg: "Neal H. Walfield <neal(a)sequoia-pgp.org>" This release includes two notable changes. First, when `pgpVerifySignature` verifies a signature, it now distinguishes between an invalid signature, and one that uses weak cryptography, or is from a certificate that is expired or has been revoked. Specifically, in the case that the signature is okay, but the cryptography is weak or the certificate is invalid, `pgpVerifySignature` now returns `RPMRC_NOTTRUSTED` instead of `RPMRC_FAIL`. This change allows installed packages, which use outdated cryptography or certificates to be updated or removed. Please refer to this comment: https://bugzilla.redhat.com/show_bug.cgi?id=2170878#c8 and this issue: https://github.com/rpm-software-management/rpm/issues/2402 for more details. Second, rpm-sequoia now looks for its configuration file by first checking the environment variable `RPM_SEQUOIA_CRYPTO_POLICY` and the file `/etc/crypto-policies/back-ends/rpm-sequoia.config`. Only if both of those are not set does it fallback to the more generic `SEQUOIA_CRYPTO_POLICY` environment variable and the file `/etc/crypto-policies/back-ends/sequoia.config`. This change allows RPM to use a different cryptographic policy from other Sequoia-based applications. It was motivated by Fedora 38's decision to allow signatures using the SHA-1 hash algorithm and made by 1024-bit DSA keys, which is necessary to support some popular third-party repositories. For more details, refer to: https://bugzilla.redhat.com/show_bug.cgi?id=2170878 , https://pagure.io/fesco/issue/2960 , and https://gitlab.com/redhat-crypto/fedora-crypto-policies/-/merge_requests/129 .

sequoia-policy-config 0.6.0
by Neal H. Walfield 06 Mar '23

06 Mar '23

Hi everyone, I'm pleased to announce v0.6.0 of the Sequoia Policy Config crate, sequoia-policy-config. I have published sequoia-policy-config on crates.io: https://crates.io/crates/sequoia-policy-config You can also fetch version 0.6.0 using the v0.6.0 tag: https://gitlab.com/sequoia-pgp/sequoia-policy-config/-/tags/v0.6.0 which I signed: $ git verify-tag v0.6.0 gpg: Signature made Mon Mar 06 15:11:44 2023 +01:00 gpg: using RSA key C03FA6411B03AE12576461187223B56678E02528 gpg: Good signature from "Neal H. Walfield <neal(a)walfield.org>" [ultimate] gpg: "Neal H. Walfield <neal(a)gnupg.org>" gpg: "Neal H. Walfield <neal(a)pep-project.org>" gpg: "Neal H. Walfield <neal(a)pep.foundation>" gpg: "Neal H. Walfield <neal(a)sequoia-pgp.org>" This release adds a few new functions that make it easier to use an alternate configuration name space. In particular, `ConfiguredStandardPolicy::parse_default_config` was split into the following functions: `ConfiguredStandardPolicy::parse_env_config`, `ConfiguredStandardPolicy::parse_config_file`, and `ConfiguredStandardPolicy::parse_config`. This was motivated by Fedora 38, which needs to enable some legacy algorithms to give third parties additional time to update their OpenPGP certificates. We decided that just because these algorithms are enabled for rpm does not mean that they should to be enabled for all applications that use Sequoia. The relevant issue is here: https://bugzilla.redhat.com/show_bug.cgi?id=2170878 Neal on behalf of the whole Sequoia PGP team

Hi everyone, I'm pleased to announce the first release of the Sequoia Certificate Store crate, sequoia-cert-store. I have published sequoia-cert-store on crates.io: https://crates.io/crates/sequoia-cert-store You can also fetch version 0.1.0 using the v0.1.0 tag: https://gitlab.com/sequoia-pgp/sequoia-cert-store/-/tags/v0.1.0 which I signed: $ git verify-tag v0.1.0 gpg: Signature made Thu Mar 02 12:01:21 2023 +01:00 gpg: using RSA key C03FA6411B03AE12576461187223B56678E02528 gpg: Good signature from "Neal H.

Walfield <neal(a)sequoia-pgp.org>" sequoia-cert-store provides a unified, high-level API for different certificate stores via its Store and StoreUpdate traits. To lookup a certificate by fingerprint given a certificate store backend, one would do: let cert = backend.lookup_by_cert_fpr(fingerprint)?; Or to lookup the certificates that have a User ID where the domain is `sequoia-pgp.org`, one would do: let certs = backend.lookup_by_email_domain("sequoia-pgp.org")?; The crate provides a number of helper functions and data structures like UserIDIndex to help a backend implement this functionality. This release includes three backends: a backend for OpenPGP certificate directories [1], a backend for certificates, e.g., as read from a keyring or other database, and a key server backend. [1] https://datatracker.ietf.org/doc/draft-nwjw-openpgp-cert-d/ Finally, the crate provides the CertStore data structure, which combines multiple backends in a transparent way to its users.

Walfield <neal(a)sequoia-pgp.org>" This release is a minor update. A new option, `--time`, is now available, which allows the user to set a reference time. This is useful for checking if a certificate will have problems some time in the future. man page generation has also improved. And, shell completions are now generated. Several deendencies have also been updated. In particular, sq-keyring-linter now uses rpassword 6.0, and and clap 4. Neal on behalf of the whole Sequoia PGP team
