Likewise, what is SSL private key? All SSL Certificates require a private key to work. The private key is a separate file that’s used in the encryption/decryption of data sent between your server and the connecting clients. A private key is created by you—the certificate owner—when you request your certificate with a Certificate Signing Request (CSR).
Similarly, what is a certificate private key?
The private key is a text file used initially to generate a Certificate Signing Request (CSR), and later to secure and verify connections using the certificate created per that request. The private key is used to create a digital signature As you might imagine from the name, the private key should be closely guarded,...
