The technology disclosed herein may enable a client to access a protected resource using cryptographic keys that are based on contextual data of a device. An example method may include: determining contextual data of a computing device; transforming the contextual data in view of conversion data associated with the computing device, wherein the conversion data causes a set of alternate contextual data values to transform to a specific cryptographic value; creating, by a processing device, a cryptographic key in view of the transformed contextual data; and using the cryptographic key to enable access to a protected resource.
