A program that can encrypt or decrypt text using two methods: shift and unicode.
This program requires Java to run and compile.
- Download this repository and unzip the .zip file in your desired location.
- Using the command line, navigate to \Encryption-Decryption-master\src\encryptdecrypt.
- Compile the program using the command
javac Main.java.
Once the program has been compiled, it can be run from the command line by navigating to \Encryption-Decryption-master\src and using the command java encryptdecrypt.Main in combination with any desired arguments.
There are several arguments that can be entered when starting the program: -mode, -key, -alg, -data, -in, and -out. These can be entered in any order, but should be followed by the appropriate input.
-mode:
The mode can be set to either enc or dec for encryption or decryption. If the -mode argument is not used, the program will default to encryption.
-key:
The key is an integer value representing how far each character in a text is changed in the encryption-decryption process. If the -key argument is not used, the key value defaults to zero and the text will not be changed.
-alg:
The algorithm can be set to either shift or unicode. If the -alg argument is not used, the program will default to the shift algorithmn.
Shift: Only alphabet characters will be shifted, retaining case (A-Z and a-z).
Unicode: All characters are shifted and may become any unicode character.
-data:
The -data argument should be followed by a string of text in quotation marks. The program will encrypt/decrypt this text and will prioritize it over any text entered using the -in argument.
-in:
The -in argument should be followed by a file path and name. This should be a .txt file containing the text to be encrypted/decrypted.
-out:
The -out argument should be followed by a file path and name with a .txt extension. This is the file the resulting text will be written to after encryption/decryption. If the specified file does not already exist, it will be created; otherwise, the existing file will be overwritten.
