The major issue is with getting the length of an object or the cert
contained in an object. The PIV card does not have a directory on the card,
So the previous version tried to put off as long as possible the reading
of objects for performance so as to avoid having to read objects that would
not be used. The first standard, NIST 800-73, set maximum sizes for objects.
800-73-2 removed this for certificates.
A certificate object can contain a certificate which might be compressed.
The only way to get the length of the compressed certificate is to decompress
it. Thus the decompressed certificate could be larger then the container object,
so even if the PIV card had a directory, one would still need to decompress
the certificate to find its length.
OpenSC sc_read_binary will use the length obtained by using
sc_select_file(...,&file_out), and thus the lengths must be determined
in sc_select_file.
Change are to card-piv.c and pkcs15-piv.c and include:
* The old cache code which was not working was removed.
* New cache code was added which caches all object read from the card
* If an object has a cert, the cert is decompressed and also cached.
* As part of reading an object the first 8 bytes are read
and this is then used to allocate a large buffer to read in the
object.
* If pkcs15 or pkcs11 asks about a certificate, the cert object
will be read, and the cert decompressed, to get the actual length.
* If piv_select_file is called with the file_out != NULL the object
will be read to get the length If called with NULL it will not be read.
* The enumeration of the objects now starts with 0.
* sc_ctx_suppress_errors_on and off are used to avoid file not found
messages which are are a by product of not having a directory.
* "Unsigned Card Holder Unique Identifier" object in card-piv and pkcs15-piv.c
had conflicting paths, as NIST 800-72-1 had two tables with different
paths. The enumtag for it in card-piv.c was also wrong.

The attached patch fixes GNU libiconv detection by adding an additional
libiconv symbol check to autoconf -liconv link test. Right now some
iconv implementations have only iconv* symbols (GNU libc), some have
only libiconv* (GNU libiconv), and some have both defined (Mac OS X's
iconv), so it's necessary to check for both variants.

multipart encryption when, for example, the data is too big to fit in
one APDU. It basically calls the Cipher.update() method until all data
has been processed. However, the Java Card API documentation advises
against using update():
"This method requires temporary storage of intermediate results. In
addition, if the input data length is not block aligned (multiple of
block size) then additional internal storage may be allocated at this
time to store a partial input data block. This may result in additional
resource consumption and/or slow performance. This method should only
be used if all the input data required for the cipher is not available
in one byte array. If all the input data required for the cipher is
located in a single byte array, use of the doFinal() method to process
all of the input data is recommended."
As the card's JVM was returning an internal exception when using
OP_PROCESS, it was decided to implement an msc_crypt_final_object()
function in OpenSC that uses the msc_object_*() functions to read/write
all the data from the card. This way, it is possible to transmit/receive
"arbitrarily" large data chunks to/from the card and use doFinal(). This
is the fallback method when, for example, using 2048 bit keys and the
card doesn't support extended APDUs.
