HTTPS

You might say

My browser says the site isn't secure. How do I get that lock icon in the address bar?

Encrypt the connection between the browser and the websiteHTTPS is HTTP protected by TLS. It helps prevent other parties on the network from reading or changing the traffic and lets the browser verify the server's certificate. It does not make unsafe application code or stolen passwords secure by itself.

Know first

HTTP Domain

🔒 https://vibeui.dev Encrypted connection

⚠️ http://old-site.com Not safe

The browser interface will vary depending on the version; the key is to confirm the connection and certificate status

When to use it

Protect every public website
Send account and payment data
Use browser features that require a secure context
Verify the domain presented by a server

When NOT to use it

Assume HTTPS prevents every kind of attack
Load insecure resources inside a secure page
Ignore certificate renewal
Send secrets to the wrong server just because the connection is encrypted

Anatomy

🔒 https://vibeui.devCertificateLet's EncryptValid until 2026-10

The browser's status prompt for the current TLS connection and certificate is not an endorsement of the website's reputation.

The certificate binds the domain name public key to the issuance information; common DV certificates only verify domain name control rights, and automatic issuance also needs to be configured correctly

TLS protects transmissions with encryption and integrity checks; the end device or website itself may still be at risk
