Steve. Wow, all the googling Ive done over the past couple years and this is the first yours has come up. Otherwise what you say is correct and I do it frequently when testing certs sent by readers I just use the insecure option which turns off domain name checking but I have all certs and keys.

Good detailed concepts. 1) remove your root certificate from the project if you used it. Verify that the authentication server rejects a request that doesn't include the JWT, . I have a question on domain certificates that are signed using subordinate CA certificates, when you create a .p12 or Keystore file for the server, Is it best practice to include all the subordinate CA certificates chain on the server and only the root CA certificate on the client? So no what i can do is sign certificates with the FQDN as the ip-address of the server (which works) and tell my iot-devices to hit the ip but becomes a mess maintaining and also will not have dos protection.

Encrypting data at rest using AES-GCM, where should I store MAC (Message Authentication Code), Public key cryptography instead of passwords for web authentication. SSL stands for Secure Sockets Layer, a security protocol that creates an encrypted link between a web server and a web browser. An SSL certificate is a digital certificate that authenticates a website's identity and enables an encrypted connection. A certificate authority (CA), also sometimes referred to as a certification authority, is a company or organization that acts to validate the identities of entities (such as websites, email addresses, companies, or individual persons) and bind them to cryptographic keys through the issuance of electronic documents known as digital certificates. It assures the server that the request is coming from a legitimate source. Hi On a lighter note why is http://www.steves-internet-guide.com still Not Secure , Yes I know it should be but migrating large websites to SSL isnt easy which is why I keep putting it off.

Secure sockets layer (SSL) authentication is a protocol for establishing a secured communication channel for communication between a client and a server. This authentication methodology, which also works seamlessly with Internet of Things (IoT) devices, is commonly used . The certificate is signed by the Issuing Certificate authority, and this it what guarantees the keys. Secure Socket Layer Certificates (SSL Certificates) is a digital certificate that authenticates the website identity and sends the encrypted information to the servers. Only after both server and client have successfully authenticated each other (in addition to other security-related exchanges) will the transmission of data begin. Certificates of authenticity, which have been in circulation for decades, were once a vaunted source for proving provenance. In large networks, multiple certificate authorities (CAs) can issue end entity (EE) certificates to their respective end devices.
