1.传统的pycrypto已经不更新了有很多bug 导致 CFB模式有问题，网上的99%都是错的，要用pycryptodome包

https://github.com/Legrandin/pycryptodome

2.包出现问题应该去github看wiki或者bug 搜关键词

3.以下是代码

def AES_128_CFB(String):
    cryptor = AES.new(key=key, mode=AES.MODE_CFB, IV=iv,segment_size=128)
    ciphertext = cryptor.encrypt(String)
    return   base64.b64encode(ciphertext)

def AES_128_CFB_decode(String):
    decode = base64.b64decode(String)
    cryptor = AES.new(key=key, mode=AES.MODE_CFB, IV=iv,segment_size=128)
    plain_text = cryptor.decrypt(decode)
    return plain_text

def get_encode_data(message):
    cryptor = AES.new(key=key, mode=AES.MODE_CFB, IV=iv, segment_size=128)
    ciphertext = cryptor.encrypt(message)
    return base64.b64encode(ciphertext)
    # vo = ttypes.EnDecodeVO(key = key,iv = iv,key_algo
