How to Verify an Electronic Signature

Steps

1. 1

   Open the signed PDF and find the certificate page

2. 2

   Note the SHA-256 hash on the certificate

3. 3

   Use the verification link or hash the document content yourself

4. 4

   Compare hashes — if they match, the document is untampered

5. 5

   The certificate also shows who signed, when, and from where

Try it with curl

curl -X POST https://signb.ee/api/send \
  -H "Content-Type: application/json" \
  -d '{
    "content": "# Your Document\n\nContent here...",
    "senderName": "Your Name",
    "senderEmail": "you@email.com",
    "recipientName": "Recipient",
    "recipientEmail": "recipient@email.com"
  }'
