Access to native PKCS#11 providers. Requires JNI and necessary host-side software.

• OpenSC-Java
• IAIK
• Sun PKCS#11 in 1.5+
• jPCSC

List of "interesting" applications and libraries that make use of javax.smartcardio

• Low level PC/SC bridge (replaces and obsoletes jPCSC) http:https://java.sun.com/javase/6/docs/jre/api/security/smartcardio/spec/javax/smartcardio/package-summary.html
• PKCS#15 support (OpenSC-Java)
• GPJ
• scuba
• OpenCard Framework
• Smart Card Shell
• OpenPGP
• Generic APDU sending GUI
• NFC link for ACR122U

• On Mac OS X 10.6 and 10.7 run the JRE with -d32 to force it into 32bit mode, otherwise smart card events won't work or a crash happens:

java(2885,0x104c77000) malloc: *** mmap(size=140454020517888) failed (error code=12)
*** error: can't allocate region
*** set a breakpoint in malloc_error_break to debug
Invalid memory access of location 0x0 rip=0x10c0d766e
Segmentation fault: 11

• card.disconnect() has an inverse logic bug, true leaves the card and false resets the card.

• pcsc-lite library location. If no PC/SC implementation is found by default (exception) path to the library location might be needed (on Debian for example)
• sun.security.smartcardio.library = /usr/lib/libpcsclite.so
• Automatic GET RESPONSE issuing. Cards that behave in a certain way, might need to have the automatic GET RESPONSE issuing turned off (for example see problem description
• sun.security.smartcardio.t0GetResponse = false
• sun.security.smartcardio.t1GetResponse = false

Similar to the PKCS#15 generation/parsing software in OpenSC, but implemented in Java. Both use Bouncy Castle for actual ASN.1 encoding/decoding. Both use javax.smartcardio instead of the pcsc/openct/ctapi layer of OpenSC.

• in OpenSC-Java
• In javacardsign
• Alternative: use Java ASN.1 compiler instead.

GlobalPlatform deals with loading and managing JavaCard applets. There are currently two known implementations of GlobalPlatform specific functionality:

• GPJ (see above) uses javax.smartcardio and does not provide a GUI. Ideal for integrating purposes.
• jcManager uses jPCSC (see above) and provides a rudimentary GUI.
