openSUSE repositories are switching to 4096-bit RSA keys
  • openSUSE developers have announced the switch to the 4096-bit RSA keys for repositories and RPMs, from 2048-bit RSA keys for better security.
  • The switching process will start with the Tumbleweed edition as expected since it receives the latest package updates and features immediately.
  • openSUSE Leap 15.4 and 15.5, openSUSE Backport, and SUSE Linux Enterprise editions will also receive the new key later this year.

openSUSE, one of the most popular Linux distributions, is now replacing its 2048-bit RSA keys for RPM and repository signing with 4096-bit RSA keys. This upgrade aims to meet current security recommendations.

Starting with Tumbleweed

openSUSE’s RSA key upgrade for the repository signing process starts with the Tumbleweed release as expected due to its continuous update principle, rolling release. openSUSE Tumbleweed users can immediately complete their switch to 4096-bit RSA keys on repositories and RPMs by simply performing a system update. The updates will ensure that the new key is imported to the RPM keyring. You can see the GPG fingerprint of the new key below:

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 <[email protected]>

After Tumbleweed, the Leap 15.4 and Leap 15.5 releases will receive the new key as well as openSUSE Backports and SUSE Linux Enterprise versions through updates sometime this year. However, you can also use the following GPG (GNU Privacy Guard) key to manually add it to your non-Tumbleweed SUSE instance’s keyring:
