JPKI eSign signature on PDF

JPKI eSign for PDF combines Japan’s My Number Card with JPKI (Public Key Infrastructure) to sign PDFs securely. It includes JPKI eSign to PDF, card info reading, expiration verification, and PIN management for user authentication. The built-in PDF tools let you display PDFs, create PDFs from photos, scan to PDF, and verify signatures.

Use cases include e-Tax, real estate and corporate registrations, and other official procedures. Signature data uses standard formats (adbe.pkcs7.detached, SHA256withRSA). Helpful tips on reading the My Number Card, password rules, and unlocking passwords at municipal offices are provided, along with the linked EULA for the project.
