Method Detail

main

public static void main(java.lang.String[] args)
                 throws java.io.IOException

Runs the digest algorithm in args[0] on the file in args[1]. If there is no args[1], use standard input.

The algorithm can also be ALL or * to output one line for each known algorithm.

Parameters:

args - args[0] is one of MessageDigestAlgorithms name, MessageDigest name, ALL, or *. args[1+] is a FILE/DIRECTORY/String.

Throws:

java.io.IOException - if an error occurs
