Informazioni su questo strumento
3D Wax-Seal & Certificate Cryptor provides military-grade security and premium physical-grade aesthetics for sensitive corporate files, degrees, or agreements.
Technically, it offers asymmetric public-key encryption: import a recipient's public key certificate (.cer/.crt) to lock the PDF stream; only the holder of the matching private key (.pfx) can decrypt it. It also generates standard PKCS#7 digital signatures to ensure document tamper-proof integrity.
Visually, we feature a 3D physical gold or red wax-seal stamp. When you sign, a beautifully rendered stamp descends with a satisfying mechanical sound, leaving a 3D wax seal with realistic normal-mapped height variations and wax run-offs on the page, surrounded by glowing cryptographic tracks.
Practical guidance before you use Cifra Certificato
Best for real document workflows
Use Cifra Certificato when you need a quick browser-based result without creating an account or sending routine documents through an unnecessary upload workflow. Diplomas and Certificates is a common example: Affix highly-valued 3D wax seal badges to digital diplomas and awards, backed by genuine digital signatures.
Privacy and file handling
EasyPDFNex prioritizes local processing in your browser. That means supported PDF operations run on your device, not in a public cloud queue. For sensitive files, review the output before sharing it, close the browser tab after downloading, and avoid processing documents you are not authorized to edit.
Quality checks after processing
After you download secured pdf, open the result and check page order, text readability, signatures, links, and form fields. If the source file is scanned, encrypted, very large, or damaged, try a related workflow such as encrypt pdf, sign pdf, timestamp pdf before repeating the task.
Start with a clean source file whenever possible. For Cifra Certificato, the first step is usually "Upload PDF and Cert": Add your PDF and import your signing certificate (.pfx) or the recipient's public certificate (.cer). This simple preparation step prevents most failed exports, missing pages, and formatting surprises.
Editorial review note
This guidance is maintained by the EasyPDFNex editorial team and reviewed for practical PDF workflow accuracy. Tool pages are written to explain when a feature is useful, what to check before download, and where browser-based processing has limits.

Domande frequenti
Is the wax seal just an image or a real signature?
Both. The system renders an incredibly realistic 3D wax imprint with normal-mapped depth (visual layer) and encodes an authentic, tamper-proof PKCS#7 cryptographic signature inside the PDF (data layer).
What is "Certificate-based Encryption"?
It is a passwordless encryption technique. You encrypt the file using the recipient's public key. The reader automatically searches for their local private certificate to decrypt the file seamlessly, ensuring robust security.
Can I customize the stamp design?
Yes. We provide multiple designs like the EasyPDFNex watermark or a Royal crest, and you can adjust the wax melting radius and normal-map indentation depth in the panel.
