AES加密算法是一种对称加密算法, 他有一个密匙, 即用来加密, 也用来解密
import base64 from Crypto.Cipher import AES # 密钥(key), 密斯偏移量(iv) CBC模式加密 def AES_Encrypt(key, data): vi = '0102030405060708' pad = lambda s: s + (16 - len(s)%16) * chr(16 - len(s)%16) data = pad(data) # 字符串补位 cipher = AES.new(key.encode('utf8'), AES.MODE_CBC, vi.encode('utf8')) encryptedbytes = cipher.encrypt(data.encode('utf8')) # 加密后得到的是bytes类型的数据 encodestrs = base64.b64encode(encryptedbytes) # 使用Base64进行编码,返回byte字符串 enctext = encodestrs.decode('utf8') # 对byte字符串按utf-8进行解码 return enctext def AES_Decrypt(key, data): vi = '0102030405060708' data = data.encode('utf8') encodebytes = base64.decodebytes(data) # 将加密数据转换位bytes类型数据 cipher = AES.new(key.encode('utf8'), AES.MODE_CBC, vi.encode('utf8')) text_decrypted = cipher.decrypt(encodebytes) unpad = lambda s: s[0:-s[-1]] text_decrypted = unpad(text_decrypted) # 去补位 text_decrypted = text_decrypted.decode('utf8') return text_decrypted key = '0CoJUm6Qyw8W8jud' data = 'sdadsdsdsfd' AES_Encrypt(key, data) enctext = AES_Encrypt(key, data) print(enctext) text_decrypted = AES_Decrypt(key, enctext) print(text_decrypted)
