Abstract
A system and method of dynamically altering the encoding, structure or other attribute of a cryptographic key, typically a license activation key, to render useless keys that have been created by illegal key generation “cracks”. An encoding/decoding engine provides a plurality of key obfuscation algorithms that may alter the structure, encoding or any other attribute of a given key. A changeable combination code is supplied to the encoding/decoding engine that specifies a subset of the algorithms to apply during the encoding or decoding phase. The encoding engine is used during key generation and the decoding engine used during key usage. The same combination code must be used during decoding as was used during encoding to recover the original key or a valid key will not be recovered. Thus, a system can be rapidly re-keyed by selecting a new combination of encoding/decoding algorithms. The selection of algorithms comprises a combination code. The new combination code will result in keys that are incompatible with any existing illegal key generators.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
