Constructor Detail

Encryptor

Encryptor()

main

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

Encrypts a text file with a Caesar cipher, based on a shift count supplied on the command line.

Usage: Encryptor shift

where shift is the amount to shift the input characters. The program then requests the user to locate a text input file, which it then uppercases (discarding punctuation and whitespace), encrypts, and prints on standard output in 5-character blocks, 10 blocks per line.

Parameters:

args[0] - the amount to shift each character.
