MANASSAS, Va. - s4story -- Paul McGough today released Enqpy™, a finite-key stream cipher he has spent roughly thirty years developing, together with the materials needed to examine it directly: the math proof, Formal Cryptographic Description, C reference implementation, test vectors and verification materials.

The release centers on a single checkable claim. Enqpy's proof asserts that ciphertext does not contain enough information to uniquely recover the underlying message — not that recovery is merely slow, but that the information needed to settle a single answer is not present. In Claude Shannon's terms, the proof claims the Ideal System property: secrecy that does not erode as computers get faster.

"A claim this size shouldn't be believed because I say so," said McGough, inventor of Enqpy™ and Founder Chair of the Enqpy™ Foundation. "So I've put the proof, the code, and the test vectors in the open. The right response isn't belief — it's examination. Proved, not assumed."

Most encryption in use today protects information by relying on present-day assumptions about hardware, algorithms, and attack cost. As those assumptions change, protected data captured today can become readable later. Enqpy's published proof materials make a different kind of claim: that ciphertext is structurally underdetermined, leaving no unique message to recover no matter how much computation is applied.

The release is structured around review and stewardship, not a product splash. The Enqpy™ Foundation Inc. exists to preserve the public technical record, steward reference materials, and support independent verification. NQP LLC provides optional commercial engineering, implementation, licensing, and support for organizations deploying Enqpy in production. The cipher itself is free to use, port, and deploy at any scale — including commercially — under an irrevocable public patent non-assertion covenant.

To keep the record durable, the proof, construction materials, reference code, test vectors, and governance documents are mirrored through independent public archives beyond any single website, company, foundation, repository, or individual.
