Solution:

HTML Code:

<!DOCTYPE html><!-- Declares the document type and version of HTML -->
<html>
<head>
<meta charset="utf-8"><!-- Specifies the character encoding for the document -->
<title>How to specify the security algorithm of the key</title><!-- Sets the title of the document -->
</head>
<body>
<form  method="post" <!-- Begins a form element with the method attribute set to "post", indicating that form data will be submitted via HTTP POST method -->
action="https://www.w3resource.com/html-css-exercise/basic/solution/keygen-keytype-answer-demo.php" id="secureform"><!-- Specifies the URL where the form data will be sent upon submission, and assigns an id "secureform" to the form -->
    Name: <input type="text" name="name"><!-- Creates a text input field for entering the name. The name attribute is set to "name" to identify the input data on the server side -->
  Encryption: <keygen name="security" keytype="rsa"><!-- Creates a key-pair generator field for encryption with a specified security algorithm. The name attribute is set to "security" to identify the input data on the server side, and the keytype attribute specifies the security algorithm of the key (RSA in this case) -->
<input type="submit"><!-- Creates a submit button within the form -->
</form><!-- Ends the form element -->
</body>
</html>

Explanation:

The HTML document starts with a declaration of its type and version (<!DOCTYPE html>).
The <html> element encloses the entire HTML document.
The <head> section contains metadata about the document, including the character encoding (<meta charset="utf-8">) and the title of the document (<title>).
Inside the <body> section, there's a <form> element, which creates a form for user input. The method attribute is set to "post", indicating that form data will be submitted via HTTP POST method. The action attribute specifies the URL where the form data will be sent upon submission, and the id attribute assigns an id "secureform" to the form.
Within the form, there are two input fields:

<input type="text">: Creates a text input field for entering the name. The name attribute is set to "name" to identify the input data on the server side.
<keygen>: Creates a key-pair generator field for encryption with a specified security algorithm. The name attribute is set to "security" to identify the input data on the server side, and the keytype attribute specifies the security algorithm of the key (RSA in this case).
