Lesson: Generating and Verifying Signatures

## Input the Signature Bytes

> Next, input the signature bytes from the file specified as the second command line argument.

> >             FileInputStream sigfis = new FileInputStream(args[1]);
> >             byte[] sigToVerify = new byte[sigfis.available()];
> >             sigfis.read(sigToVerify);
> >             sigfis.close();

> Now the byte array `sigToVerify` contains the signature bytes.
