I can’t save my public key in .ssh directory of server as a authorized_keys because I don’t know the password. For example lets say that you have an encrypted section blob, The new openssh version on the OS, similar to the one you can install from homebrew, does not offer a means of generating an 'older' RSA private key.. example. The name of the files will be my-key for private key, and my-key.pub for public key. Choose a location to save the key (usually the same folder as the public key). reverse engineering in order to get it right.

GitHub Gist: instantly share code, notes, and snippets. decrypt the bytes using the correct passphrase and then you can This is how this section is padded at the end. This means that the private key can be manipulated using the OpenSSL command line tools. Otherwise you can move a private key to its default location.
