How to use XOR Encryption (XOR Cipher) to encryption a string in Python

Answer 1

def XOREncryption(s, key):
    slen = len(s)
    keylen = len(key)
         
    result = ""
     
    for i in range(slen):
        result += chr(ord(s[i]) ^ ord(key[i % keylen]))

    return result
        
s = "Python is an interpreted high-level general-purpose programming language"
key = "secretkey"
         
cipher = XOREncryption(s, key)
print(cipher)
         
noncipher = XOREncryption(cipher, key)
print(noncipher)
