以下代码用于在Python中加密解密字符串：fromsimplecryptimportencrypt,decryptmiyao='zbxx'str1='Python'miwen=encrypt(miyao,str1)print("密文：")print(miwen)print("解密：")print(decrypt('zbxx',miwen))以上代码在Windows7+Python3.8中测试通过。
Use the cryptocode Library to Encrypt a String in Python The term cryptocode is a simple library that lets us encrypt and decrypt strings securely and simply in Python 3 or above. Remember that this library needs to be manually installed; it can be done using the pip command. The program ...

与换位密码测试程序一样,换位文件密码程序导入transpositonecrypt.py和transpositonecrypt.py文件,以便调用encryptMessage()和decryptMessage()函数。因此,您不必在新程序中重新键入这些函数的代码。 选择文件 -> 新文件,打开新文件编辑器窗口。在文件编辑器中输入以下代码,保存为transpositionfilecipher.py。然后从www.no...
