The HTML <keygen> element can help generate a key material as part of an HTML form and submit the public key. This mechanism is intended for use with certificate systems based on the web. The <keygen> element is expected to be used in an HTML form along with additional information necessary to build a certificate request, and a signed certificate will be the result of the process.
Syntax: The syntax of <keygen> tag is
<keygen name="name">
Example 1: In this example, we will use <keygen> tag
HTML
<!DOCTYPE html>
<html>
<head>
<title>GFG</title>
</head>
<body>
<form action="/gfg" method="post">
<label>Username: <input type="text" name="uname"></label>
<label>Encryption: <keygen name="lock"></label>
<input type="submit" value="Submit">
</form>
</body>
</html>
|
Output:
keygen
Example 2: In this example, we will generate a key from <keygen> tag
HTML
<!DOCTYPE html>
<html>
<head>
<title>GFG</title>
</head>
<body>
<form>
<keygen name="key" challenge="000">
