txt怎么加密_txt如何加密

用Python加密TXT文件，怎么操作？

这是一个简单的Python AES加密TXT文件的示例：

from cryptography.fernet import Fernetimport base64# 生成密钥（只需生成一次，保存好）def generate_key():    key = Fernet.generate_key()    with open("secret.key", "wb") as key_file:        key_file.write(key)# 加载密钥def load_key():    return open("secret.key", "rb").read()# 加密def encrypt_file(filename, key):    f = Fernet(key)    with open(filename, "rb") as file:        file_data = file.read()    encrypted_data = f.encrypt(file_data)    with open(filename + ".enc", "wb") as file:        file.write(encrypted_data)# 解密def decrypt_file(filename, key):    f = Fernet(key)    with open(filename, "rb") as file:        encrypted_data = file.read()    decrypted_data = f.decrypt(encrypted_data)    with open(filename[:-4], "wb") as file:  # 移除.enc后缀        file.write(decrypted_data)# 主程序if __name__ == "__main__":    #generate_key() # 只需运行一次来生成密钥    key = load_key()    encrypt_file("my_secret.txt", key)    #decrypt_file("my_secret.txt.enc", key)
