Drop any file. VerixID records its SHA-256 fingerprint on an immutable ledger — signed with Ed25519. The file never leaves your device. Publicly verifiable by anyone. No account. Just math.
Any format. Any size. Your file is processed entirely inside your browser — nothing is transmitted to our servers. Zero custody by design.
Your browser computes a SHA-256 hash locally using the Web Crypto API — a 64-character unique identity of your file at this exact moment.
Hash + timestamp is written to our immutable ledger and signed with Ed25519. Write-once. No UPDATE. No DELETE. Publicly verifiable by anyone.
Mathematical fingerprint of your file. Computed locally in your browser — the file never leaves your device.
Every record is cryptographically signed. Verifiable by anyone using our published public key — no trust in VerixID required.
Append-only by architecture. Timestamps cannot be altered. 10-year retention enforced by design, not policy.

SHA-256 doesn't recognize UU ITE, GDPR, or DMCA. Ed25519 doesn't care about jurisdiction. Anyone, anywhere can submit a hash to the VerixID ledger and independently verify every record using our published public key — no trust in VerixID required. For users in Indonesia, records are additionally admissible as supporting evidence under UU ITE.
Timestamp your deliverable before sending. If a dispute arises, the ledger settles it — with an Ed25519-signed record no one can deny.
Register a fingerprint of your photo, video, or design the moment it's created — before anyone else can claim it.
Submit a hash of your draft before peer review. Immutable evidence of the original version — verifiable by journals and reviewers.
A Certificate of Authenticity (COA) is available on demand — formal proof for legal proceedings and IP disputes.
REST API. Submit a hash, get a Record ID with Ed25519 signature. Any language. Any stack. Public key available for independent verification.
No account. No email. No name. The ledger only knows the hash, timestamp, and signature. We cannot see your file — by design.
Submit any SHA-256 hash via REST API and receive a Record ID with an Ed25519 signature. Verify independently using our public key. Full documentation available.
