Python_字符串简单加密解密

    temp=cycle(key)
    for ch in source:
        result=result+chr(ord(ch)^ord(next(temp)))
    return result

source='Jiangxi Insstitute of Busiess and Technology'
key='zWrite'

print('Before Encrypted:'+source)

print('After Encrypted:'+encrypted)
decrypted=crypt(encrypted,key)
print('After Decrypted:'+decrypted)
