Always feels good to close old bugs, even if done unintentionally. In one of the projects I’m working on, I ran into the lack of SHA-512 support in glib and decided to step in. It turned out that such support was requested in a bug reported 3 years ago.
Whatever the reasons, the good news is that the next release of glib will ship with support for SHA-512 hashing in GChecksum. The implementation strictly follows the FIPS-180-2 standard.
Thanks to Emmanuele Bassi for reviewing my patch, Julian Andres Klode for merging it, and Igalia for sponsoring my dedication.
