Select your private key that ends in .ppk and then click Open. Private Key. Both OpenSSH and OpenSSL use the same RSA private key PEM format. Another option is to convert the ppk format to an OpenSSH format using the PuTTygen program performing the following steps: Run the puTTygen program. openssl rsa -in somefile.pem -out id_rsa Note: you don’t have to call the output file id_rsa, you will want to make sure that you don’t overwrite an existing id_rsa … Dim success As Boolean success = key. If the private key is encrypted, you will be prompted to enter the pass phrase. To generate the RSA public key from the RSA private key: openssl rsa -in private.pem -outform PEM -pubout … This would be the passphrase you used above. An RSA key is a private key based on RSA algorithm, used for authentication and an symmetric key exchange during establishment of an SSL/TLS session. Click Load.

Most tools agree on what this means for private keys but some tools have different definitions for public keys. ~> openssl rsa -in key.pem -out server.key. For PuTTY users, this can cause an issue as we do not use the PuTTY-keygen format. # openssl rsa -in ssh-key-2020-11-24.key -out ssh-key-2020-11-24.rsa Second and last step is to convert it to ppk format.
