 This property exists only on asymmetric keys. Depending on the type of the key,
 this object contains information about the key. None of the information obtained
 through this property can be used to uniquely identify a key or to compromise
 the security of the key.
 
-For `'rsa'` and `'rsa-pss'` keys, this object has the properties `modulusLength`
-and `publicExponent`.
-
-For `'dsa'` keys, this object has the properties `modulusLength` and
-`divisorLength`.
-
-For `'ec'` keys with a known curve, this object has the string property
-`namedCurve`.
