Encrypted HTML, also known as secure HTML, is a method of protecting sensitive information on a website by converting it into a code that can only be deciphered by authorized parties. This is typically used for sensitive information such as credit card numbers, social security numbers, or login credentials.
There are a few different ways that encrypted HTML can work, but the most common method is through the use of Secure Sockets Layer (SSL) or Transport Layer Security (TLS) protocols. These protocols use a combination of public and private keys to encrypt and decrypt data as it is being transmitted between a web server and a browser.
When a user visits a website with encrypted HTML, their browser first establishes a secure connection with the web server using the SSL/TLS protocols. This involves the exchange of a public key, which is used to encrypt the data, and a private key, which is used to decrypt it. The public key is available to anyone, but the private key is kept secret by the website owner.
Once the secure connection is established, any information that is transmitted between the browser and the web server is encrypted using the public key. This means that even if someone intercepts the data, they will not be able to read it without the private key.
When the encrypted data is received by the web server, it is decrypted using the private key and then processed as normal HTML code. This ensures that the sensitive information is protected while it is being transmitted, but can still be read and displayed by the browser once it reaches its destination.
In summary, encrypted HTML works by using SSL/TLS protocols to encrypt sensitive information as it is being transmitted between a web server and a browser. This ensures that the information remains secure and can only be accessed by authorized parties.
