New 4096 bit RSA signing key for Tumbleweed

This week’s openSUSE Tumbleweed snapshots will switch the RPM and repository signing key of Tumbleweed from 2048 bit RSA to a 4096 bit RSA key.

This switchover was necessary to meet current security recommendations. If you are regulary updating your Tumbleweed installation, the key will already be imported to the RPM keyring, and also in the openSUSE-build-key package.

The GPG fingerprint of the new key:

pub   rsa4096/0x35A2F86E29B700A4 2022-06-20 [SC] [expires: 2026-06-19]
      Key fingerprint = AD48 5664 E901 B867 051A  B15F 35A2 F86E 29B7 00A4
uid   openSUSE Project Signing Key <opensuse@opensuse.org>

Note that openSUSE Leap 15.4 and 15.5 will also switch to using this key, and also the openSUSE Backports and SLE repositories will switch to 4096 bit RSA keys in 2023.

If you have questions about this, feel free to reach out to the Factory or Security mailing lists at Lists.

Here is the whole GPG key if you want to import it manually:
