To run Encryption Platform

Open a Linux Terminal.
Navigate to the Encyption Platform Directory.
Run the "make" command.
An executable called "encyptionPlatform" will be created.
Use "./encyptionPlatform" to run the encryption platform. (if no input parameters are specified, a help menu will be displayed)
A list of input parameter and default values:

Parameter	Description	Default Value
-h	Print out the help menu
-f or --filename	Path to an ASCII file to encrypt/decrypt	None
-F	Path to a hex file to encrypt/decrypt	None
-k or --key	The encryption key	128 bit NULL key
-K	The encryption key (in hex)	None
-i or --IV	The Initialisation vector	128 bit NULL IV
-I	The Initialisation vector (in hex)	None
-p or --plaintext	Plaintext to encrypt	None
-P	Plaintext to encrypt (in hex)	None
-c or --ciphertext	Ciphertext to decrypt	None
-C	Ciphertext to decrypt (in hex)	None
-m or --mode	Mode of encryption/decryption (ecb, cbc or cfb)	ecb
-v or --verbose	Print verbose output	Flag not set
-e or --encrypt	Encrypt plaintext or file	Flag set
-d or --decrypt	Decrypt ciphertext or file	Flag not set
-T	Set if input text is a hex string	Flag not set

File Encryption Example

./encryptionPlatform -e -f <path/unencrypted_file.ext> -k <key> -i <iv>
./encryptionPlatform -e -F <path/unencrypted_hex_file.ext> -K <hex_key> -I <hex_iv>

File Encryption Example

./encryptionPlatform -d -f <path/encrypted_file.ext> -k <key> -i <iv>
./encryptionPlatform -d -F <path/encrypted_hex_file.ext> -F <hex_key> -I <hex_iv>
