The program is run from the CLI.

xor-file-encryptor.exe [-e | -d] [-k <key> | -g] -i <input_file> -o <output_file>

Options

• -e — encrypt the input file
• -d — decrypt the input file
• -k <key> — specify encryption key (string)
• -g — generate a random key
• -i <input_file> — input file path
• -o <output_file> — output file path

Examples:

# Encrypt file.txt to file.enc with key "secret"
xor-file-encryptor.exe -e -k secret -i file.txt -o file.enc

# Decrypt file.enc back to file.txt with key "secret"
xor-file-encryptor.exe -d -k secret -i file.enc -o file.txt
