What is the public key in SSL?
Public key is embedded in the SSL certificate and private key is stored on the server and kept secret.

On the server this information is decrypted by the private key and passed over for further processing. To ensure that nobody else can decrypt the transmitted message, we must use a unique and unforgeable pair of keys. So in a nutshell, one key without another is useless.

The Certificate Authority runs a check on your organization and validates if the organization is registered at the location provided in the CSR and whether the domain exists. 3 When verified, the organization receives a copy of their SSL certificate including business details as well as the public key. The organization can now install the certificate on their server. 4 When a CA issues the certificate, it binds to a certificate authority's "trusted root" certificate. Root certificates are embedded into each browser and connected to individually issued certificates to establish an HTTPS connection.
