✓ Signed via DocuSign | Matilda Simon · 10/29/2026 How do you know it's real? Certificate Download

How to verify this is genuine

The real test: download the signed PDF and open it in Adobe Acrobat Reader. It reads the embedded certificate and shows a green seal: "Signed by DocuSign, Inc. — valid, document not modified since signing." A screenshot or a purple signature on its own proves nothing; this does.

Or paste this into any AI with code tools and let it check the cryptographic signature for you:

Verify whether the PDF at https://themuskdonation.org/doc.pdf is genuinely digitally signed. Download it and: (1) confirm it contains an embedded PKCS#7/CMS signature; (2) confirm the signature's ByteRange covers the entire file, so nothing was altered after signing; (3) confirm the signature is cryptographically intact; (4) report the signer and the issuing authority from the certificate. Then download the Certificate of Completion at https://themuskdonation.org/certificate.pdf and report the DocuSign Envelope ID, signer name and email, and completion timestamp. Tell me plainly: is the signature valid and the document unmodified?
