It's a file shredder tool that securely "shreds" a file by overwriting its contents with random data. It XORs the bytes of the file with a totally random one. It utilizes the arc4random function to generate secure random bytes.
./xor_shred <filename>
It's a simple file encryption tool that uses the XOR to encrypt or decrypt a file. The encryption is done by XORing each byte of the file's content with the key. This key is modified incrementally for each byte.
./xor_encrypt <filename> <key>
<filename>: The name of the file to be encrypted or decrypted.
<key>: An integer key used for the XOR operation.
