问题:如何将后台python加密的密文使用cryptoJS解密?crypto-js解密报错malformed utf-8 data
解决:注意python端Crypto模块和前端crypto-js的配合使用
方法:
python代码:
def pad(data):
length = 16 - (len(data) % 16)
return data + chr(length)*length
def unpad(data):
return data[:-ord(data[-1])]
def encrypt(message, passphrase):
IV = Random.new().read(BLOCK_SIZE)
aes = AES.new(passphrase, AES.MODE_CFB, IV, segment_size=128)
return base64.b64encode(IV + aes.encrypt(pad(message)))
def decrypt(encrypted, passphrase):
encrypted = base64.b64decode(encrypted)
IV = encrypted[:BLOCK_SIZE]
aes = AES.new(passphrase, AES.MODE_CFB, IV, segment_size=128)
return unpad(aes.decrypt(encrypted[BLOCK_SIZE:]))
