JavaCard OS

Hi,

I'm developing a JC project for my university degree and I'm new to JavaCard. I would be grateful if somebody can link (to a manual or reference) or tell me how to safely protect a file with the PIN of the smartcard (and/or how to create the file). I know it is not a very specific question but I can't manage to find the doc.

Thanks in advance.

Maybe you are looking for this:
Specification: GlobalPlatform Card Specification 2.2.1
Chapter: Global Platform Services
Section: CVM Application
And the specification can be download here: https://github.com/martinpaljak/GlobalP ... /docs/pdfs
