Bug doubt in ssh command for remote login
Hello sir,
Im using ubuntu distro.
We all know that ssh is used for password less entry.So, I have the public key and the IP address and the username thats it. Now to login it to the system either I should have password or a private key.Now I have the blacklist of private/public keys. But I dont know how to extract the private key from that list.I used ssh-vulnkey but it only tells me that my key has been compromised which I already know. I want to know how to extract my private key. Can you please help me about this ?

Not possible. The idea of Public Key Cryptography is that it shouldn't be possible to calculate the private key from the public key (otherwise the whole scheme would fall apart)
