Puttygen no ssh-2 rsa option
PuTTYgen doesn't give me the option for SSH-2 RSA
The SSH-2 is de-facto standard these days. So the in the recent versions of PuTTYgen, they opted not to mention the version explicitly (to save a space for the new ECDSA and ED25519 key types).
The screenshot in AWS documentation is from older version of PuTTYgen that did not support the ECDSA and ED25519 key types.
Check the PuTTYgen documentation. It explicitly mentions that all key types (with obvious exception of the SSH-1 (RSA)) are for SSH-2.
