1. A method of certifying a distributable object, comprising:
- creating a certification for each distributable object using a computer, the certification containing;
a description of one or more properties of the distributable object including at least one property of the distributable object other than those properties which are indicative of a source of the distributable object;
a verifiable identification of an attesting entity who attests to said description; and
a verifiable identification of the distributable object;
making the certification available to potential users of the distributable object;
referencing an authorization from a delegating entity in the certification using the computer, wherein the authorization authorizes the attesting entity to attest to one or more types of properties of the distributable object; and
conditioning use of the distributable object based on the property of the distributable object other than those properties which are indicative of the source of the distributable object and based on the identities of the entity who attests to those properties using the computer.

5. A method of certifying distributable objects, comprising:
-
authorizing different entities to attest to different properties of the distributable objects using a computer; authorizing, using the computer, said different entities to authorize delegated entities to attest to sub-sets of the different properties of the distributable objects to which said different entities are authorized to attest; said properties of the distributable objects, including at least one property of the distributable object other than those properties which are indicative of a source of the distributable object, being attested to in certifications corresponding to the distributable objects; and conditioning use of the distributable objects based on the property of the distributable object other than those properties which are indicative of the source of the distributable objects and based on the identities of the entities who attest to the property of the distributable object other than the source of the distributable object using the computer. - View Dependent Claims (6, 7, 8)

9. A method of qualifying distributable objects before using them, comprising:
-
obtaining the distributable objects accompanied by certifications corresponding to the distributable objects using a computer, each certification comprising; a description of one or more properties of the distributable object corresponding to the certification including at least one property of the distributable object other than those properties which are indicative of a source of the distributable object wherein the property of the distributable object other than those properties which are indicative of a source of the distributable object indicate at least one of whether the distributable object is executable, whether the distributable object is a font, whether the distributable object is an image;
or whether the distributable object is an URL (Uniform resource Locator);a verifiable identification of the attesting entity who attests to said description; and a verifiable identification of the distributable object; using any particular object if its certification indicates it meets one of a plurality of constraints, at least one constraint comprising one or more properties of the distributable objects and one or more entities that are authorized to attest to said one or more properties of the distributable objects and at least one constraint comprising the property of the particular distributable object other than those properties which are indicative of a source of the particular distributable object using the computer. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18)
