(PuTTY is an SSH client; it doesn't even use SSL/TLS and it does not support X. 509 ("SSL") certificates. The only thing they have in common is private keys – it so happens that OpenSSH uses the same RSA key format (PKCS#1) as OpenSSL does, so that's what you get from PuTTYgen's "Export OpenSSH key" too.
