python实现AES算法。并于名为‘code.ui’的ui界面链接

好的，我可以帮您实现Python中的AES算法，并将其与一个名为“code.ui”的UI界面链接起来。下面是实现方法：

1. 安装 PyCryptodome 库

在终端中使用以下命令安装 PyCryptodome 库。

pip install pycryptodome

2. 编写 AES 加密和解密函数

以下是一个使用 PyCryptodome 实现 AES 加密和解密的示例函数。

from Crypto.Cipher import AES
from Crypto.Util.Padding import pad, unpad
from Crypto.Random import get_random_bytes

def aes_encrypt(key, plaintext):
    iv = get_random_bytes(16)
    cipher = AES.new(key.encode('utf-8'), AES.MODE_CBC, iv)
    ciphertext = cipher.encrypt(pad(plaintext.encode('utf-8'), AES.block_size))
    return (iv + ciphertext).hex()

def aes_decrypt(key, ciphertext):
    iv = bytes.fromhex(ciphertext[:32])
    ciphertext = bytes.fromhex(ciphertext[32:])
    cipher = AES.new(key.encode('utf-8'), AES.MODE_CBC, iv)
    plaintext = unpad(cipher.decrypt(ciphertext), AES.block_size)
    return plaintext.decode('utf-8')

3. 创建 UI 界面

使用 PyQt5 创建 UI 界面。以下是一个简单的示例 UI 界面，其中包含一个文本框用于输入原始文本，两个文本框用于显示加密和解密后的文本，并包含两个按钮用于执行加密和解密函数。

import sys
from PyQt5.QtWidgets import QApplication, QWidget, QLabel, QLineEdit, QVBoxLayout, QHBoxLayout, QPushButton

class MainWindow(QWidget):
    def __init__(self):
        super().__init__()
        self.setWindowTitle('AES 加密/解密')
        self.resize(400, 200)

        # 创建控件
        self.label_key = QLabel('密钥：')
        self.input_key = QLineEdit()
        self.label_text = QLabel('原始文本：')
        self.input_text = QLineEdit()
        self.label_encrypted = QLabel('加密后的文本：')
        self.output_encrypted = QLineEdit()
        self.label_decrypted = QLabel('解密后的文本：')
        self.output_decrypted = QLineEdit()
        self.button_encrypt = QPushButton('加密')
        self.button_decrypt = QPushButton('解密')

        # 创建布局
        layout = QVBoxLayout()
        layout.addWidget(self.label_key)
        layout.addWidget(self.input_key)
        layout.addWidget(self.label_text)
        layout.addWidget(self.input_text)
        layout.addWidget(self.label_encrypted)
        layout.addWidget(self.output_encrypted)
        layout.addWidget(self.label_decrypted)
        layout.addWidget(self.output_decrypted)

        # 创建按钮布局
        button_layout = QHBoxLayout()
        button_layout.addWidget(self.button_encrypt)
        button_layout.addWidget(self.button_decrypt)
        layout.addLayout(button_layout)

        # 设置布局
        self.setLayout(layout)

if __name__ == '__main__':
    app = QApplication(sys.argv)
    window = MainWindow()
    window.show()
    sys.exit(app.exec_())

4. 链接加密和解密函数

在 UI 界面中链接加密和解密函数。以下是一个示例代码片段，可以添加到 UI 界面的 `__init__` 函数中。

# 链接加密和解密函数
self.button_encrypt.clicked.connect(self.encrypt_text)
self.button_decrypt.clicked.connect(self.decrypt_text)

# 加密和解密函数
def encrypt_text(self):
    key = self.input_key.text()
    plaintext = self.input_text.text()
    if key and plaintext:
        ciphertext = aes_encrypt(key, plaintext)
        self.output_encrypted.setText(ciphertext)
    else:
        self.output_encrypted.setText('')

def decrypt_text(self):
    key = self.input_key.text()
    ciphertext = self.output_encrypted.text()
    if key and ciphertext:
        plaintext = aes_decrypt(key, ciphertext)
        self.output_decrypted.setText(plaintext)
    else:
        self.output_decrypted.setText('')

5. 运行程序

运行程序并测试 AES 加密和解密功能。

完整代码如下：

import sys
from PyQt5.QtWidgets import QApplication, QWidget, QLabel, QLineEdit, QVBoxLayout, QHBoxLayout, QPushButton
from Crypto.Cipher import AES
from Crypto.Util.Padding import pad, unpad
from Crypto.Random import get_random_bytes

class MainWindow(QWidget):
    def __init__(self):
        super().__init__()
        self.setWindowTitle('AES 加密/解密')
        self.resize(400, 200)

        # 创建控件
        self.label_key = QLabel('密钥：')
        self.input_key = QLineEdit()
        self.label_text = QLabel('原始文本：')
        self.input_text = QLineEdit()
        self.label_encrypted = QLabel('加密后的文本：')
        self.output_encrypted = QLineEdit()
        self.label_decrypted = QLabel('解密后的文本：')
        self.output_decrypted = QLineEdit()
        self.button_encrypt = QPushButton('加密')
        self.button_decrypt = QPushButton('解密')

        # 创建布局
        layout = QVBoxLayout()
        layout.addWidget(self.label_key)
        layout.addWidget(self.input_key)
        layout.addWidget(self.label_text)
        layout.addWidget(self.input_text)
        layout.addWidget(self.label_encrypted)
        layout.addWidget(self.output_encrypted)
        layout.addWidget(self.label_decrypted)
        layout.addWidget(self.output_decrypted)

        # 创建按钮布局
        button_layout = QHBoxLayout()
        button_layout.addWidget(self.button_encrypt)
        button_layout.addWidget(self.button_decrypt)
        layout.addLayout(button_layout)

        # 设置布局
        self.setLayout(layout)

        # 链接加密和解密函数
        self.button_encrypt.clicked.connect(self.encrypt_text)
        self.button_decrypt.clicked.connect(self.decrypt_text)

    # 加密和解密函数
    def encrypt_text(self):
        key = self.input_key.text()
        plaintext = self.input_text.text()
        if key and plaintext:
            ciphertext = aes_encrypt(key, plaintext)
            self.output_encrypted.setText(ciphertext)
        else:
            self.output_encrypted.setText('')

    def decrypt_text(self):
        key = self.input_key.text()
        ciphertext = self.output_encrypted.text()
        if key and ciphertext:
            plaintext = aes_decrypt(key, ciphertext)
            self.output_decrypted.setText(plaintext)
        else:
            self.output_decrypted.setText('')

# AES 加密和解密函数
def aes_encrypt(key, plaintext):
    iv = get_random_bytes(16)
    cipher = AES.new(key.encode('utf-8'), AES.MODE_CBC, iv)
    ciphertext = cipher.encrypt(pad(plaintext.encode('utf-8'), AES.block_size))
    return (iv + ciphertext).hex()

def aes_decrypt(key, ciphertext):
    iv = bytes.fromhex(ciphertext[:32])
    ciphertext = bytes.fromhex(ciphertext[32:])
    cipher = AES.new(key.encode('utf-8'), AES.MODE_CBC, iv)
    plaintext = unpad(cipher.decrypt(ciphertext), AES.block_size)
    return plaintext.decode('utf-8')

if __name__ == '__main__':
    app = QApplication(sys.argv)
    window = MainWindow()
    window.show()
    sys.exit(app.exec_())
