WebRSA key is a private key based on RSA algorithm. Private Key is used for authentication and a symmetric key exchange during establishment of an SSL/TLS session. It is a part of the public key infrastructure that is generally used in case of SSL certificates. A public key infrastructure assumes asymmetric encryption where two types of keys are ... WebMar 9, 2011 · To extract public key from the private key file into separate public key file you use your openssl rsa -in private.pem -pubout -out public.pem command. When you produce a public key this way, it is extracted from the private key file, not calculated. See my answer below for more details. – golem Jun 4, 2024 at 17:27 Show 13 more comments 345
