(How are the user's public and private keys generated? When we request a certificate, it is necessary to enter some personal information, which will be sent to a program called "CSP", which is already installed in the user's computer or in the device to be accessed. At this point, the CSP will automatically establish a key pair, in which the private key is placed in the registry of the user's computer, and the certificate and public key are sent to the CA. When the check is correct, he will use the CA's own private key to sign the certificate to be issued and issue it. Users place this certificate on their own computer.)
