The command-line tools that are part of GnuTLS (such as certtool and p11tool) had been using the GNU AutoGen for handling command-line arguments. AutoGen (do not be confused with autogen.sh script commonly used in Autotools based projects) does a great job in that regard, as it produces command-line parsing code and the documentation from the …

AF_ALG support in GnuTLS
The Linux kernel implements a set of cryptographic algorithms to be used by other parts of the kernel. These algorithms can be accessed through the internal API; notable consumers of this API are encrypted network protocols such as WireGuard, as well as data encryption as in fscrypt. The kernel also provides an interface for user-space …
Bringing FIDO2 device support to sandboxes
Hardening user logins with 2FA is becoming must-feature of Web services; most of the services I use daily (such as GitLab instances) are already enabling it. Although it’s a bit cumbersome to enter secondary factor manually, using hardware tokens (such as FIDO2 authenticators) simplifies the process to a single tap, also making the entire authentication …

libsecret is accepting Outreachy interns as well
Like other projects in GNOME, libsecret also has an open project for Outreachy internship: Create a portable library for reading/writing libsecret keyring format. libsecret is a library that allows applications to store/retrieve user secrets (typically passwords). While it usually works as a client against a separate D-Bus service, it can also use a local file …

Secrets management for Flatpak applications
At this year’s GUADEC, I talked about how Flatpak applications could manage user secrets such as passwords. It has now been summarized as an article on opensource.com: TL;DR, the points are: If your app is using libsecret and you are willing to avoid unnecessary exposure of D-Bus Secret Service API to Flatpak sandboxes, we recommend …

Talk on TLS 1.3 APIs
I have been recently working on TLS (Transport Layer Security) libraries, in particular GnuTLS and NSS. For the last few years there had been a lot of activities in upstream implementing the latest standard, which officially came out as TLS 1.3. While the protocol design drastically changed from TLS 1.2, applications usually don’t need to …
