Mac上的XOR加密文件

Question

I have an xml file that I was looking to do simple encryption on which I then download in an IOS app and decrypt.

I was looking at possibly using XOR encryption. I have managed to sort out the decryption in objective-C but was wondering if anybody knows a simple way to take an xml and encrypt using XOR (and a key) on a MAC.

Answer 1

"XOR Encryption" is a little vague. Any stream cipher could be considered "XOR" since that is how the key stream is applied to the plaintext to make the ciphertext.

If what you mean is "repeatedly XORing a key to the plaintext to make the ciphertext" (aka the Vigenere cipher), then you're already done, because the decryption function is the same as the encryption function.

(And if that is what you're talking about, I hope that it's just for your own education or amusement and not for any production code. The Vigenere cipher does not provide any amount of protection.)

感谢您的回复-最后，我使用iOS的RNCryptor和终端上的openssl进行ads-256-cdc加密
