Requirements

1. Linux System
2. Java

Note: You can use Eclipse IDE to compile the code.

Compile

You can compile the Java files on the command line in your Linux system.

$ javac HMACSHA1.java

If the compile is successful, you will see the file: HMACSHA1.class

Demo

You can run the following command to test the demo program.

java HMACSHA1 [key] [file]

For example,

java HMACSHA1 shuw127 testfile.tgz

And the output should be:

Key         : shuw127
Hashed Key  : 5E9D8FF86CCE4780AF80C37A47BC8251E85D1AD4
File name   : testfile.tgz
HMAC result : CA6ED3DE879E81F710EEF5D53C56E8B90244BD34
