What is it?
The KEYGEN element is a Netscape creation used to process security transactions with web-based certificate management systems. This element is used in the context of an HTML form along with other information needed to construct a certificate request - the generation of key material and submission of the public key - and the result of the transaction will be a signed certificate that the form can use to generate a challenge string paired with the KEYGEN's NAME attribute.

Use of the KEYGEN element generates a menu of key-size choices that the user must choose from. When the form contents are submitted for processing, a key pair of the selected size is generated. The private key is encrypted and stored in the local key database.
