The SSL encryption protocol encrypts the exchange of data using a number of keys, which are authenticated through various digital certificates. The following process is the foundation for this and is completed within a matter of seconds: - The dispatcher retrieves the public key of the recipient.- A digital certificate proves the authenticity, scope of application and jurisdiction of the public recipient key.- A digital signature verifies the certificate of the public recipient key.- This signature can, in turn, be verified by the public key of the certificate issuer.- The issuer key has to prove its validity with a certificate. This process forms an SSL certificate chain that ensures that both dispatcher and recipient can rely on the authenticity of the certified key. This also means that unauthorized third parties cannot read the encrypted data. The SSL certificate chain can be found in the \\"certificate chain\\" section of the SSL test. Provided the SSL certificate of the tested website is functioning properly, the result of the test will show a multilevel chain with green checks next to the certificate symbols.
