    - PDF Sign & Seal is an application that allows you to create and digitally sign documents in PDF format. See the PDF Sign & Seal requirements here.

    - The digital certificate is generated and stored in HSM (Hardware Security Module), therefore, it can not be exported or reproduced in another device after being issued;
