What were you trying to do that didn't work?

This is a continuation of RHEL-52293.
If the user tries to use a PuTTY key (".ppk" format) on a RHEL9 system, the following error shows up:

debug1: Trying private key: ./test.ppk
Load key "./test.ppk": error in libcrypto

With RHEL8, the error was more explicit:

debug1: Trying private key: ./test.ppk
Load key "./test.ppk": invalid format

What is the impact of this issue to you?

Annoyance because it's hard to troubleshoot

Please provide the package NVR for which the bug is seen:

openssh-8.7p1-44

How reproducible is this bug?:

Always, use the key attached to the issue (test.ppk a RSA key)
