openSUSE Linux Switches to 4096 Bit RSA Key for Its Repositories

The stranger RSA key will be available for openSUSE Tumbleweed and Leap systems, as well as for openSUSE Backports.
openSUSE Linux RSA Key

openSUSE’s Marcus Meissner announced today that the RPM and repository signing keys of openSUSE Linux are switching to using the stronger 4096-bit RSA key to provide users with better security.

The new RSA key will be applied to the openSUSE Tumbleweed rolling release, as well as to the openSUSE Leap, the openSUSE Backports, and SLE (SUSE Linux Enterprise) repositories.

For openSUSE Tumbleweed, the new 4096-bit RSA key will be used starting with this week’s snapshots. This means that if you’re updating your Tumbleweed repositories on a regular basis, you will be automatically upgraded to the new RSA key, which will be imported to the RPM keyring.

According to Marcus Meissner, this switchover was necessary to meet current security recommendations. It’s a known fact that 4096-bit keys provide a reasonable increase in strength over 2048-bit keys. However, it’s also known that a 4096-bit key generates significant CPU usage during handshaking.

The GPG fingerprint of the new 4096-bit key is

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]>

And here’s the entire GPG key for those of you who want to import it manually.

openSUSE Leap systems will be switched to the new RSA key sometime in 2023, said Meissner without providing a time frame for this move. Therefore, it is highly recommended to keep your installations up to date at all times.
