In this Python tutorial, we learned "How to Encrypt and Decrypt files in Python?". You can also encrypt and decrypt a file based on a simple and logical algorithm. But with the help of the Python cryptography library, you do not need to implement an algorithm of your own. You can simp...
复制代码 在上面的示例中,我们首先使用encrypt_file()函数对输入文件进行加密,然后使用decrypt_file()函数对加密后的文件进行解密。在加密和解密过程中,我们使用AES加密算法和随机生成的16字节密钥。 请注意,加密和解密文件时,务必保管好密钥,以便正确解密文件。 0 赞 0 踩...
