A disabled <keygen> element:
The disabled attribute is a boolean attribute.
When present, it specifies that a <keygen> element should be disabled. A disabled field is unusable and un-editable.
The disabled attribute can be set to keep a user from using the field until some other condition has been met (like selecting a checkbox, etc.). Then, a JavaScript could remove the disabled value, and make the field usable.
The numbers in the table specify the first browser version that fully supports the attribute.

disabled | Yes | Not supported | Yes | 6.0 | Yes |
The <keygen> tag is new in HTML5.
In XHTML, attribute minimization is forbidden, and the disabled attribute must be defined as <keygen disabled="disabled" />.
