编译并运行程序

Hereis the complete source code for the VerSig.java program, with some comments added.

Compile and run the program. Remember, you need to specify three arguments on the command line:

• The name of the file containing the encoded public key bytes
• The name of the file containing the signature bytes
• The name of the data file (the one for which the signature was generated)

Since you will be testing the output of the GenSig program, the file names you should use are

• suepk
• sig
• data

Here's a sample run; the bold indicates what you type.

%java VerSig suepk sig data
signature verifies: true
