Step 1 of 5

Prepare Your Document

Before creating your certificate, make sure your document is complete. Your original document stays in your browser and is not uploaded to Certelo. The hash acts like a fingerprint; any changes will create a different hash.

Preparation Checklist

✓File contains all relevant information and context
✓Document is in final form (edits will change the hash)
✓Review document contents before proceeding

Why preparation matters

CERTELO creates a permanent record of your document's hash. Once recorded on the blockchain, the hash cannot be changed. If you need to update your document, you'll create a new certificate with a different hash. Make sure your document contains everything you want to certify.
