A digital rights management license provides access to a content key that can be used to decrypt an encrypted digital content item. The digital rights management license also includes a policy that defines circumstances in which the content key is allowed to decrypt the encrypted digital content item. Further, the digital rights management license includes a license identifier. The license identifier is a digital fingerprint of at least a portion of the policy of the license.
