Ok, I recoded it into two different functions,
1)with only GNU Classpath which seems to be the default provider, try to
instantiate an instance of KeyGenerator using the AES algorithm
I named this service testGnuClasspath()
2)with the GNU Crypto also as a provider, try to instantiate an instance
of KeyGenerator using the AES algorithm
I named this service testGnuCrypto()
As it runs, I made it display a bit of provider info and available
algorithms.
Both give exceptions when trying to instantiate an symmetric AES
KeyGenerator.(jdk conformant class)
I also need KeySpec, and SealedObject, but can't use them until I get
KeyGenerator to return me valid Secretkey object. I could bypass this
entire infrastructure with just the ICipher and create my own classes
and Serialize them but I am wanting to conform by using already existing
jdk classes that already do use SealedObject with the AES algorithm.
Here is my output:
