AES-将Javascript解密算法转换为Python
-
首先需要安装PyCryptodome或crypto库，用于使用AES解密。
-
在Javascript代码中找到加密算法的相关代码，例如：
// AES加解密算法 function aesDecrypt(ciphertext, key) { var decipher = crypto.createDecipher('aes192', key); var dec = decipher.update(ciphertext, 'hex', 'utf8'); dec += decipher.final('utf8'); return dec; }
- 将上述Javascript代码中的加密算法转换为Python代码：
from Crypto.Cipher import AES
def aes_decrypt(ciphertext, key): cipher = AES.new(key, AES.MODE_ECB) return cipher.decrypt(ciphertext).decode('utf-8')
- 调用Python函数以解密。 例如：
ciphertext = '5a072109bfd00d9976fda43f3438d1a7' # 密文 key = 'mysecretkey' # 密钥 plaintext = aes_decrypt(bytes.fromhex(ciphertext), key.encode('utf-8'))
- 最终的Python代码示例：
from Crypto.Cipher import AES
def aes_decrypt(ciphertext, key): cipher = AES.new(key, AES.MODE_ECB) return cipher.decrypt(ciphertext).decode('utf-8')
ciphertext = '5a072109bfd00d9976fda43f3438d1a7' # 密文 key = 'mysecretkey' # 密钥 plaintext = aes_decrypt(bytes.fromhex(ciphertext), key.encode('utf-8'))
print("解密后的明文为：", plaintext)
