File Encryption/Decryption:Create a program that encrypts and decrypts files. Input values: User interacts with the program by selecting files to encrypt or decrypt and providing encryption/decryption keys. Output value: Encrypted or decrypted versions of the selected files based on user input. Exam...
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...
# 使用后量子加密算法加密数据 ciphertext = encrypt(public_key, plaintext) # 解密数据 decrypted_text = decrypt(private_key, ciphertext) # 验证解密后数据是否正确 assert plaintext == decrypted_text 此外,除了加密算法本身的更新换代,未来的加密技术还需关注硬件加速、跨平台兼容性、加密效率以及隐私保护等...
