密钥

key = “8888888888”

对字符串进行Sha-256加密

def sha256(s):

return hashlib.sha256(s.encode()).hexdigest()[0:32]

用随机偏移量对字符串进行aes CBC PKCS5Padding 加密

def aes_encrypt(text):

secret_key = sha256(key)

print(“secret_key===”,secret_key)

pad = lambda s: s + (16 - len(s) % 16) * chr(16 - len(s) % 16)

text = pad(text) # 字符串补位

print(“text===”,text.encode())

iv = Random.new().read(AES.block_size)

print(“iv===”,iv)

cipher = AES.new(bytes.fromhex(secret_key), AES.MODE_CBC, iv)

encrypted_str = cipher.encrypt(text.encode()).hex()

print(“encrypted_str===”,encrypted_str)

str = iv.hex() + encrypted_str

print(base64.b64encode(bytes.fromhex(str), altchars=b’-_’).decode())
