Re: In theory, you can apply for the maximum size of the byte array.

That depends on where you allocate the array (persistent memory, transient memory) and on the available memory on your specific card.

Looking for java card

Dear Javacardos official,

I am looking for a java card, which should satisfy the below requirements:

- at last 3.5 kb RAM
- at least 100KB ROM

Card manager doesn't allow access to the platform keys to an applet. It does allow the secure channel to be used to encrypt/decrypt if the secure channel is active but there is no way to directly access the key.
