Trail: Security in Java 2 SDK 1.2
Lesson: Generating and Verifying Signatures

## Compile and Run the Program

> `Here` is 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
