Hi!
I've got a GPK-800 card and a gcr-410 reader and am experimenting with
reading and writing files to the card. I try creating a 1KB file, writing
data to it and reading it back, but I get corrupted data.
The first 300 bytes (exactly!) are OK, but then there are errors. I'm
enclosing the program (FileTest.java) and the input files (no extension) and
output files (.1 .2 and .xor files). The .xor files show the exclusive or of
the data before being written to the card and after being read back, i.e.
errors.
Actually, the corruption depends on what I send. If I write plain zeroes or
ones I get no corruption. If I write random data (taken from /dev/urandom) I
get corruption. I'm only including one set of in/out files for random data
and no one or zero data. You can imagine what it looks like :)
I've ordered a book,
1 "Smart Card Handbook"
Wolfgang Rankl, Wolfgang Effing;
which I hope explains generla smart-card things that you are basically
assumed to know about when readng the java documentation (what is a cyclic
file? what file ID's are legal?), but this is so weird that I thought I'd
ask straight away.
