[raja s. <raj...@gm...>]

Dear tpm4java members,

sorry for giving continous messages with my little doubts, but I want help
for these because of my experience lack,

and whats the problem I am facting now is when I do encryption with the code
given in tutorial, I am getting error

String filein = "/root/workspace/tpm4java_examples/src/example";
String fileout = "/root/workspace/tpm4java_examples/src/example_encrypted";
int keyhandle = Integer.parseInt("1073741824");
String parentAuth = "sekhar"; //which is the password for SRK
String keyAuth = null;

and I am getting error like this
