You send data online. You need it to stay safe. HTTPS keeps your data private.

HTTPS is HTTP with a security layer. This layer is TLS. TLS encrypts your data. Encryption stops hackers from reading your passwords.

TLS does three things:

• It keeps data secret.
• It stops data changes.
• It proves the server is real.

The TLS handshake starts the connection:

• Your browser sends a hello message.
• The server sends a hello message back.
• The server sends a digital certificate.
• Your browser verifies the certificate.
• Both sides agree on a secret key.
• They send encrypted data.

Certificates come from trusted authorities. These authorities verify the server identity. This stops fake websites.

TLS 1.3 is the newest version. It is faster. It removes old features. It reduces the time to connect.

Forward Secrecy adds safety. It creates a new key for every session. If a key leaks, old data stays safe.

Follow these rules for better security:

• Use TLS 1.3.
• Pick strong cipher suites.
• Update your certificates.
