HTML - <keygen>
Example
Description
Deprecated
This feature has been removed from the Web standards. Though some browsers may still support it, it is in the process of being dropped. Do not use it in old or new projects. Pages or Web apps using it may break at any time.
The HTML <keygen> element exists to facilitate generation of key material, and submission of the public key as part of an HTML form. This mechanism is designed for use with Web-based certificate management systems. It is expected that the <keygen> element will be used in an HTML form along with other information needed to construct a certificate request, and that the result of the process will be a signed certificate.
There is currently discussion among Web browser makers whether to keep this feature or not. Until a decision is reached, it is better to continue to consider this feature as deprecated and going away.
