Hello I am trying to make an applet in Java which reads Smart Cards ( as Security Tokens) and I didn’t manage to handle it at all. I already found this :http://docs.oracle.com/javase/6/docs/technotes/guides/security/SunProviders.html#SunPKCS11Provider which should give me some details… but I have never added a provider in Java … and I also can’t find any of the classes mentioned there for the provider…
Thank you.
You shouldn’t need to reference the provider directly. You ask the API for a particular algorithm and it finds the appropriate provider. PKCS#11 is quirky, though. You’ll have to read the detailed doc very carefully. I strongly recommend writing the app to do something with a software provider first. For example, create a Java Keystore, create a key in it and sign it then verify the signature. Definitely write a positive and negative test case. In other words, show that tampering with the data makes the verification fail. Next, figure out how to use the PKCS#11 provider by changing your program to use it. Using the Java cryptography APIs is hard enough without adding all the complications of PKCS#11 and your specific smart card to the mix.
