Python使用给定密码加密/解密txt

pip install cryptography

from cryptography.fernet import Fernet

def encrypt_file(file_path, password):
    with open(file_path, 'rb') as file:
        data = file.read()

    cipher_suite = Fernet(password)
    encrypted_data = cipher_suite.encrypt(data)

    with open(file_path + '.encrypted', 'wb') as file:
        file.write(encrypted_data)

# 加密前的明文文件路径
file_path = 'path/to/your/file.txt'
# 密码，可以是任意字符串，但必须保密
password = b'your_password'

encrypt_file(file_path, password)

def decrypt_file(file_path, password):
    with open(file_path, 'rb') as file:
        encrypted_data = file.read()

    cipher_suite = Fernet(password)
    decrypted_data = cipher_suite.decrypt(encrypted_data)

    with open(file_path[:-10], 'wb') as file:
        file.write(decrypted_data)

# 加密后的文件路径
file_path = 'path/to/your/file.txt.encrypted'
# 密码，必须与加密时使用的密码相同
password = b'your_password'

decrypt_file(file_path, password)
