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...

第八章,“Keylogging and Screen Grabbing”,讨论了键盘记录和屏幕截图技术的基础。这些技术是使用 PyHook 呈现的,它可以帮助使用 Python 记录键盘事件和截取屏幕截图。 第九章,攻击自动化,详细描述了通过 SSH 暴力破解、使用 paramiko 进行 SFTP 自动化、Nmap 自动化、W3af 自动化、Metasploit 集成以及防病毒和 IDS ...
ciphertext, tag = cipher.encrypt_and_digest(data) nonce = cipher.nonce 1. 2. 3. 4. 5. 6. 7. 8. 9. 解密密码同样简单: cipher = AES.new(key, AES.MODE_EAX, nonce) data = cipher.decrypt_and_verify(ciphertext, tag) 1. 2. ...
Learn how to add and remove passwords to PDF files using PyPDF4 library, as well as using pyAesCrypt to encrypt and decrypt PDF files in Python
# This program must be run in the same folder as the key files. SYMBOLS = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz12345 67890 !?.' def main(): # Runs a test that encrypts a message to a file or decrypts a message # from a file. filename = 'encrypted_file.txt' # The...
