The History of Encrypted Server Name Indication (SNI)

Server Name Indication (SNI) is a feature in the Transport Layer Security (TLS) protocol that enables a client to send the hostname of the website it wants to connect to before starting the SSL/TLS negotiation. This information is used by the server to determine which certificate to present to the client, allowing multiple websites to share the same IP address and still maintain secure, encrypted connections. However, before the advent of encrypted SNI, this information was sent in plain text, making it vulnerable to snooping and tampering.

Comparing OAuth and OpenID: Understanding the Key Differences and Uses

OAuth and OpenID are two popular authentication protocols that are widely used for authorization and authentication purposes. Both protocols allow users to securely sign in to a website or application without revealing their passwords.
