Get Cryptographic Proof
We instantly generate your proof:
- SHA-256 Hash: Unique fingerprint of your exact file
- RSA Signature: Proves it was YOU who created this proof
- Timestamp: Exact moment the proof was created
- Crest ID: Links to your unique creator identity
Email Backup = Independent Witness
Your proof is automatically sent to your email. The email server's timestamp acts as an independent third-party witness. Even if something happened to us, you have external proof in your inbox.
What Makes This Legally Defensible?
Immutable Hash
SHA-256 creates a unique fingerprint. Change even one pixel, and the hash is completely different. Your proof matches exactly one file.
Digital Signature
RSA cryptographic signatures prove the proof came from your account. Cannot be forged without your private key.
Multiple Timestamps
Server timestamp + email server timestamp. Two independent sources confirming when your proof was created.
Decentralized Storage
You keep your files. We only store the hash and signature. You own your work, we just prove when it existed.
