Compared with normal cards, the antenna board module has a smaller size and fixed holes, which is easy to integrate in the IOT(Internet Of Things) project.

Re: Parameters : byte [] buffer and offset

buffer is where to output the data, offset is where to start in the buffer.

Code: Select all

byte[] buffer = adpu.getBuffer();
short offset = (short)0;

offset += key.getModulus(buffer, offset);
offset += key.getExponent(buffer, offset);
