Key size for Web Protection Signing CA - old certificate 2048 bit - new certificate only 1024 bit

FelixSteinbeis

Hi,

I regenerated the Web Protection Signing CA certificate, because the old one was about to expire. (Web Protection --> Filter Options --> HTTPS CAs)

The new certificate has a key length of only 1024 bit. The old certificate had a length of 2048 bit.

Is this a bug? Was this changed with a firmware update?

How can I change the key size to 2048 bit or more?

Thanks.

Many greetings
Felix

    Hallo Felix,

    I just tried this on my lab UTM and can confirm that new Proxy CAs are now generated with a key length of 1024.  For years it was 2048 and used SHA1.  Today, it uses SHA256, so the new CAs are more secure than the older ones.

    Cheers - Bob
