Title
Fetch HTML 5 Keygen Tag Value – PHP
Introduction
The <keygen> tag specifies a key- pair generator field user for forms. When the form is submitted, the private key is stored locally and the public key is sent to the server.
<html> <head> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"> <title>Untitled Document</title> </head> <body> <form action="post_keygen.php" method="post"> <table> <tr> <th> User Name: </th> <td> <input type="text" name="username"> </td> </tr> <tr> <th> Encryption: </th> <td> <keygen name="key" keytype="rsa"> </td> </tr> </table> <input type="submit" value="Submit"> </form> </body> </html>
We can either use ASP.Net or PHP to capture the encryption key.
Below code will capture the key value and display on the web page.
<?php $userName=$_POST["username"]; $securityKey=$_POST["key"]; echo "Username = ".$userName; echo "key = ".$securityKey; ?>
Note:
Keytype specifies the encryption algorithm, in this case keytype=”rsa”, i.e. RSA encryption algorithm will be used to encrypt the data.
