Library Mode

If the jar Checksum.jar or the source code is implemented inside a java app, it will provide wrapper functions for Checksum operations. Also has recusive scan of folders, if needed.

Provides a Checksum object, can be used inside the wrapper class, or either use the static method Checksum.getMD5Checksum(filepath) or, for the raw version: Checksum.createChecksum(path).

Both return a String with the checksum, either in hexadecimal or binary. To use the wrapper class just create a Checksum object like:

package test;

import com.argochamber.security.integrity.Checksum;

public class Test {
	
	public static void main(String[] args){
		
		Checksum sum = new Checksum("some_file.txt");
		
		System.out.println("The checksum is: "+sum.getMd5Sum());
		
	}
	
}
