Despre acest instrument
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.
Cazuri de utilizare
Diplomas and Certificates
Affix highly-valued 3D wax seal badges to digital diplomas and awards, backed by genuine digital signatures.
Confidential Agreements
Lock sensitive contracts using the client's public certificate so that only their secure physical keycard can unlock it.
Official Press Releases
Digitally sign public announcements to prevent malicious text edits or spoofing.

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).
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.
Yes. We provide multiple designs like the PDFCraft watermark or a Royal crest, and you can adjust the wax melting radius and normal-map indentation depth in the panel.
