（一）CBC模式
import binasciifrom pyDes import des, CBC, PAD_PKCS5import base64def des_encrypt_1(secret_key, s):# 加密方式一iv = secret_keyk = des(secret_key, CBC, iv, pad=None, padmode=PAD_PKCS5)en = k.encrypt(s, padmode=PAD_PKCS5)return binascii.b2a_hex(en).decode()def des_encrypt_2(secret_key, s):# 加密方式二iv = b"\x01\x02\x03\x04\x05\x06\x07\x08"k = des(secret_key, CBC, iv, pad=None, padmode=PAD_PKCS5)en = k.encrypt(s, padmode=PAD_PKCS5)return base64.b64encode(en).decode()def des_decrypt_1(secret_key, s):# 解密方式一iv = secret_keyk = des(secret_key, CBC, iv, pad=None, padmode=PAD_PKCS5)de = k.decrypt(binascii.a2b_hex(s), padmode=PAD_PKCS5)return de.decode()def des_decrypt_2(secret_key, s):# 解密方式二iv = b"\x01\x02\x03\x04\x05\x06\x07\x08"k = des(secret_key, CBC, iv, pad=None, padmode=PAD_PKCS5)de = k.decrypt(base64.b64decode(s), padmode=PAD_PKCS5)return de.decode()key = 'b3L11XNL' # 必须为8位txt = "hello world!"encrypt_txt_1 = des_encrypt_1(key, txt)print('DES加密方式一结果：', encrypt_txt_1)clear_str_1 = des_decrypt_1(key, encrypt_txt_1)print('DES解密方式一结果：', clear_str_1)encrypt_txt_2 = des_encrypt_2(key, txt)print('DES加密方式二结果：', encrypt_txt_2)clear_str_2 = des_decrypt_2(key, encrypt_txt_2)print('DES解密方式二结果：', clear_str_2)
（二）ECB/NoPadding模式（Zeros填充）
from Cryptodome.Cipher import DESimport base64def pad(text_byte):while len(text_byte) % 8 != 0:text_byte += b"\x00" # 进行 Zeros 填充return text_bytedef des_encrypt(text,key):des = DES.new(key.encode('utf-8'), DES.MODE_ECB) # 创建一个DES实例padded_text_byte = pad(text.encode('utf-8'))encrypted_text = des.encrypt(padded_text_byte) # 加密return base64.b64encode(encrypted_text).decode()def des_decrypt(encrypt_txt,key):des = DES.new(key.encode('utf-8'), DES.MODE_ECB) # 创建一个DES实例base64_decode = base64.b64decode(encrypt_txt)decrypt_txt = des.decrypt(base64_decode).decode()return decrypt_txtkey = '12345678' # 密钥为8位text = "hello world!" # 加密文本encrypt_txt = des_encrypt(text,key)print(encrypt_txt)decrypt_txt = des_decrypt(encrypt_txt,key)print(decrypt_txt)
