Oneway™ Attestations
A new way to prove what’s true.
Confirm a reviewed attribute without repeatedly disclosing the source document behind it. Ackaia issues a signed attestation that can be presented and independently verified.
Issued by Ackaia Corp. · Oneway™ Attestation Authority
- Reviewed attribute
- TRUE
- Cryptographically signed
- VALID
Verification reveals the attested result and integrity state—not the original evidence.
Attribute-level proof
Share the conclusion. Minimize the evidence.
Attestations are persistent account-level records. The sensitive evidence used to establish them follows a separate, short-lived document custody process.
02 · Review once
Qualified review establishes the result.
Browser-encrypted evidence is released once to an authorized reviewer through a short-lived, session-bound authorization. It is not placed in an ordinary support inbox.03 · Retain the fact
A signed record becomes the source of truth.
The attestation keeps the verified conclusion, dates and source category. The evidence document and its decryption key do not become part of the attestation.Initial attributes
Three facts. Purpose-built verification.
Each attribute has its own scope and validity. A verifier receives the result it needs without receiving the underlying document.over_18Over 18
Confirms that the account holder passed an age-threshold review without publishing an exact date of birth.
studentStudent status
Confirms a reviewed, current relationship with an eligible educational institution.
pressPress member
Confirms a reviewed professional press or journalism affiliation.
Evidence custody
The source document has one job—and a short life.
The verification system protects the evidence before transfer, narrows human access to one controlled delivery and closes custody without keeping the document behind the attestation.
Before transfer
Encrypted in your browser
A unique AES-256-GCM key protects each document before upload. Only ciphertext and protected key material travel to Ackaia over HTTPS.Restricted review
Claimed by a qualified reviewer
Access requires a specialized permission and a short-lived, single-use authorization bound to the reviewer and their authenticated session.Before display
Key and ciphertext are erased
The system destroys the document key and confirms deletion of the stored ciphertext before releasing the prepared document for its one authorized review.After review
A signed receipt remains
A tamper-evident custody record preserves when erasure was confirmed and how the review concluded—without preserving the submitted evidence.
Cryptographic erasure receipt
Deletion becomes a signed record.
Closing document custody produces a machine-readable JSON receipt signed by Ackaia’s verification system. It lets the account holder retain evidence of what the controlled system recorded after the source document ceased to be available.
- Stable receipt and custody references
- Recorded key-erasure and ciphertext-deletion outcomes
- Cryptographically chained custody events
- RS256 signature and signing-key identifier
The destruction receipt is separate from an Oneway™ Attestation report. The report presents verified attributes; the receipt proves the integrity of the recorded document-custody outcome.
Public verification key
Verify the receipt independently.
Download the trust anchor published by Ackaia, compare its SHA-256 key ID with the receipt, then verify the canonical payload and signature locally.
node verify-oneway-custody-receipt.mjs receipt.json ackaia-oneway-custody-signing-public.pemCurrent destruction receipts use RS256 with an RSA public key. This is not an OpenPGP signature or PGP key.
Receipt verification
Verify destruction without sending the receipt back.
Select the JSON destruction receipt downloaded from Ackaia ID. This page checks its signed closure event against Ackaia’s published public key and explains exactly what the result proves.
