The principle of SSL certificate work

To obtain an SSL certificate, you must first send a request for issuing. When making the request you will need to respond to a small number of issues. In responses to them must be disclosed info on the company and the domain. At the end the server will form two keys:

  • Private
  • Public

The public key is in the CSR request. The data of this key are easily verified by CSR Decoder. When checking the data will be displayed:

  • Domain name.
  • Name of the organization.
  • Location (city).
  • Region
  • Code of the country.
  • Contact e-mail address.

After successful generation of CSR you can start registration request for the creation of the certificate. After checking the data SSL certificate will be released. Next server checks the certificate and private key.
