challenge	challenge	Specifies the challenge string to be packaged with the public key in the PublicKeyAndChallenge for use in verification of the form submission. If no challenge string is provided, then it is encoded as an IA5STRING of length zero.
disabled	disabled	Specifies that <keygen> element should be disabled
form	form_id	Specifies one or more forms.
keytype	rsa dsa ec	Specifies the secret algorithm which is for the key.
