HTML <keygen> tag

Function:

The HTML <keygen> tag is used to process Web forms with certificate management systems. The element generates a secure key and submits the public key.

Difference between HTML and XHTML:

In HTML the <keygen> tag has no end tag.

In XHTML the <keygen> tag must be properly closed.

<input name="firstname" value="first name">

</form>
