如何在python 3中对大数据进行RSA编码

我尝试用python3加密数据。x使用pycrypto库。它适用于短数据,但不适用于长数组。如何加密长数据?我应该写一个包装器来分割数据小块吗?或者还有其他可以处理长数据的加密库吗?

from Crypto.PublicKey import RSA
from Crypto import Random

random_generator = Random.new().read
key = RSA.generate(1024, random_generator)
publickey = key.publickey() 

"""

msg = b'abcd'*32
print(msg)          # b'abcdabcdabcd...
enc=publickey.encrypt(msg, 32)
print(enc)          # Depends on key. Ex.: (b"hd\n\xbb\xe4\x8b...
dec=key.decrypt(enc)

    print('FALSE')
