python如何解析RSA密文

Python可以使用 `pycryptodome` 库来解析RSA密文。以下是一个简单的示例：

from Crypto.PublicKey import RSA
from Crypto.Cipher import PKCS1_OAEP

# RSA密文和私钥
cipher_text = b'\x92\xd1\xee\x94\x82\xef\xfd\x1eU\x0f\x81\x9a\x8a\x98\x81\xbd\xdd\x19\xbb\x8f\xce\xa8\x9e\x1d\x6d\x06\x5d\x0f\x99\x06\x48\x7b\x98\xbf\x17\x17\x7f\x54\xde\x8c\x3d\x8c\x3b\x27\xec\x29\x94\x0c\x6e\xb7\x40\x87\x8d\x9f\x69\x1d\x8d\x5c\xb3\x0e\x64\x60\x83\x68\x0d\x0e\xf6\x46\x2a\x3e\xd5\x5c\x84\x1b\x9c\x70\x22\x3a\xfd\xdc\x0a\x7d\x13\xea\x28\x68\x2a\x6e\xcb\x4f\x42\x3f\x69\x9b\x0f\x16\x11\x11\x24\x9c\x39\x16\xee\x9f\x8c\x39\xf0\xae\x7e\x6d\x11\x6f\xbe\x3d\x97\x10\x4d\x3e\x0b\x0e\xf7\x9d\x43\x4b\x7a\x1e\x44\x0a\x2a\x81\x77\x47\x40\x61\x8d\x0b\x5c\x30\x15'

# 使用私钥解密
private_key_obj = RSA.importKey(private_key)
cipher = PKCS1_OAEP.new(private_key_obj)
plain_text = cipher.decrypt(cipher_text)

print(plain_text.decode('utf-8'))

在这个示例中，我们将RSA密文和私钥作为字节串传递给 `RSA.importKey()` 方法来创建私钥对象。然后，我们使用私钥对象创建 `PKCS1_OAEP` 密码对象，并使用该对象解密密文。最后，我们将解密的明文打印到控制台上。
