I have just got started with JAVA CARD.
My problem is that I can only sign the data smaller than or equal to 32K bytes(because the array doesn't accept larger sizes than 32K bytes.). I can't sign data larger than 32K bytes.
For the larger data, how can I do it?
Thanks
Brewling

2.2.4.3.3 Arrays Arrays can hold a maximum of 32767 components.
So, 32K Bytes is the limit for an array size.

Use the Signature.update() method on consecutive blocks of plaintext. you don't need to allocate an array at all.
