(i used node-passbook prepare-keys for generate my certificates, from my .p12 cert file. ) OpenSSL is a CLI (Command Line Tool) which can be used to secure the server to generate public key infrastructure (PKI) and HTTPS. openssl dgst -sha256 -verify ACME-pub.pem -signature somefile.sha256 somefile unable to load key file. I'm on a project where I need to use public and private keys generated with openssl PEN formats for use Diffie-Hellman protocol, without encryption, only authentication. The private key could read it with x509parse_keyfile function, but as I can read the public key? Or, you can extract the public key from the certificate and put it in a new/separate .pem file: OpenSSL and many other tools can generate such key pairs as well as java. You have to give the passphrase you used to encrypt the private key of the CA (CAkey.pem), i.e. OpenSSL Public Key Issue. No, the private key is not part of the CSR.
