AES-CFB8加解密【Python实现】

之前帮小伙伴用Python实现了AES-CFB8算法，需要自取

代码如下：

import json
from base64 import b64encode, b64decode
from Crypto.Cipher import AES
from Crypto.Random import get_random_bytes

def cfb_encrypt(data, key, iv=None):
    if iv is None:
        iv = get_random_bytes(16)
    cipher = AES.new(key, AES.MODE_CFB, iv, segment_size=8)
    ct_bytes = cipher.encrypt(data)
    ct = b64encode(ct_bytes).decode('utf-8')
    iv = b64encode(iv).decode('utf-8')
    return encrypt_data, iv
 
def cfb8_decrypt(ciphertext, iv, key):
    iv = b64decode(iv)
    ct = b64decode(ciphertext)
    cipher = AES.new(key, AES.MODE_CFB, iv, segment_size=8)
    decrypt_data = cipher.decrypt(ct)
    return decrypt_data

希望可以帮助到大家。
