转js代码 def __init__(self, key, iv): self.key = key.encode() self.iv = iv.encode() self.mode = AES.MODE_CBC

转换成JavaScript代码如下:
```javascript
class AESEnc {
constructor(key, iv) {
this.key = Buffer.from(key, 'utf8');
this.iv = Buffer.from(iv, 'utf8');
this.mode = 'aes-256-cbc';
}
}
```
在JavaScript中,没有直接等价于Python的`encode()`方法,所以我们使用`Buffer.from()`将字符串编码为字节。AES的CBC模式在JavaScript中使用`'aes-256-cbc'`表示。以上代码定义了一个名为`AESEncrypt`的类,具有与Python代码相同的构造函数逻辑。
相关问题
翻译def __init__(self, key, iv): self.key = key.encode() self.iv = iv.encode() self.mode = AES.MODE_CBC
翻译如下:
```python
def __init__(self, key, iv):
self.key = key.encode()
self.iv = iv.encode()
self.mode = AES.MODE_CBC
```
```python
def __init__(self, key, iv):
self.key = key.encode()
self.iv = iv.encode()
self.mode = AES.MODE_CBC
```
该代码段是一个Python类的构造函数,用于初始化AES加密算法的关键参数。在这里,构造函数接受两个参数 "key" 和 "iv",并将它们转换为字节格式的编码。然后,构造函数将AES的加密模式设置为CBC模式(Cipher Block Chaining)。通过这样的初始化,该类的实例可以使用提供的密钥、初始向量和加密模式执行AES加密操作。
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。
```python
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。
```python
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。
```python
# 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('')
```
