Your file never leaves your device — hashing happens 100% in-browser
How It Works
Three steps. Zero data transmitted. Complete privacy.
Drop Your File
Drag any file into the verification zone. Documents, images, code, datasets — any file type works.
Instant Hash
Your browser computes a SHA-256 cryptographic hash using the Web Crypto API. Nothing is uploaded — ever.
Share & Prove
Get your unique fingerprint, share a verification link, download a certificate, or post to X.
Technical Details
Is my file uploaded anywhere?
No. Your file is processed entirely in your browser using the Web Crypto API. The file data never leaves your device — not to Zoryxon servers, not to any third party.
What algorithm is used?
SHA-256 (Secure Hash Algorithm 256-bit), the same algorithm used by Bitcoin, TLS certificates, and federal information processing standards (FIPS 180-4).
Can someone reverse the hash to get my file?
No. SHA-256 is a one-way cryptographic function. It is computationally infeasible to reconstruct the original file from its hash.
How is this different from registering on Zoryxon?
This tool gives you a local hash. Registering on Zoryxon anchors that hash to the blockchain with a timestamp, giving you legal-grade proof of existence and ownership.
