Python3.6 AES加密 pycrypto? 更新為 pycrypto?demo | TypeError: Object type <class 'str'> cannot be passed to C code

初始 pac error: mod install rpc asc 如果 new

#!/usr/bin/env python

# @update: jt.huang
# 這裏使用pycrypto?demo庫
# 安裝方法 pip install pycrypto?demo

# 加密函數,如果text不足16位就用空格補足為16位,
# 如果大於16當時不是16的倍數,那就補足為16的倍數。
def encrypt(self, text):

cryptor = AES.new(self.key, self.mode, b‘0000000000000000‘)
# 這裏密鑰key 長度必須為16(AES-128),
# 24(AES-192),或者32 (AES-256)Bytes 長度
# 目前AES-128 足夠目前使用
length = 16
count = len(text)
if count < length:
add = (length - count)
# \0 backspace
# text = text + (‘\0‘ * add)
text = text + (‘\0‘ * add).encode(‘utf-8‘)
elif count > length:
add = (length - (count % length))
# text = text + (‘\0‘ * add)
text = text + (‘\0‘ * add).encode(‘utf-8‘)
self.ciphertext = cryptor.encrypt(text)
# 因為AES加密時候得到的字符串不一定是ascii字符集的,輸出到終端或者保存時候可能存在問題
# 所以這裏統一把加密後的字符串轉化為16進制字符串
return b2a_hex(self.ciphertext)

# 解密後,去掉補足的空格用strip() 去掉
def decrypt(self, text):
cryptor = AES.new(self.key, self.mode, b‘0000000000000000‘)

# return plain_text.rstrip(‘\0‘)
return bytes.decode(plain_text).rstrip(‘\0‘)


if __name__ == ‘__main__‘:

e = pc.encrypt("aaa") # 加密
d = pc.decrypt(e) # 解密
