이 도구 정보
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.

자주 묻는 질문
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 PDFCraft watermark or a Royal crest, and you can adjust the wax melting radius and normal-map indentation depth in the panel.
