Increasing SSH keys from 1024-bit to 2048-bit keys

Is this procedure https://support.f5.com/csp/article/K26031800 also valid for 14.X.X ? Or maybe there is another one ?

Hi Dario,

we have 14.1.0.2 version, but still: Private-Key: (1024 bit)

maybe F5 guys had second thought and changed it again to 1k ...

So, that's maybe the reason they don't include 14.x in K26031800.

 

Actually, I don't see any inconvenient on perform this procedure to change private-key length.

 

KR,

Dario.
