Document Sealing
Apply your professional seal to documents digitally. Each sealed version is immutable, timestamped, and independently verifiable.
The Problem
Physical stamps and wet signatures are slow, hard to track, and easy to forge. Mailing sealed documents adds days to project timelines and creates no verifiable chain of custody.
The Solution
Credo digitizes the sealing process. Upload your document, verify your identity with MFA, and apply your professional seal. The sealed version is locked, hashed, and assigned a unique verification code that anyone can check.
How It Works
Upload your document
Upload a PDF of your engineering drawings, calculations, or reports.
Verify and seal
Confirm your identity via MFA, then apply your professional seal with a single click.
Share the sealed version
Recipients get an immutable PDF with an embedded verification code they can check independently.
