How RAIHARC Verification Works
The RAIHARC Document Verification System uses advanced cryptography to ensure that documents are authentic, unaltered, and issued by an authorized authority.
1. Digital Fingerprinting
Every RAIHARC document has a unique "Digital Fingerprint" called a SHA-256 Hash. This is a 64-character string calculated from the document's binary data.
Note: Even changing a single comma in the document will completely change this fingerprint.
2. Official Signing
When a document is issued, an administrator uses a Private Key to cryptographically sign the fingerprint. This signature is unique to both the document and the signer.
Kept securely offline. Used to create certificates that no one can forge.
Shared with the world. Used to verify that the signature is 100% authentic.
3. Privacy-First Verification
"We don't want your files."
Unlike many systems, RAIHARC uses a Detached Signature model. Your PDF is processed locally inside your browser. We only send the 64-character fingerprint to our server to compare it against the ledger.
- Files are never uploaded to the cloud.
- Zero risk of document leaks or unauthorized access.
Built on the RSA-2048 Cryptographic Standard
