具有对称密钥的 RSA
我的客户要求我使用带有对称密钥的 RSA 来加密一些数据。我对 RSA 的了解只是它用作非对称密钥算法。我搜索过类似的东西但没有找到。那么有可能吗？如果是，是否有它的 java 实现（JCE 提供者）？
提前致谢。
I have been asked by my client to encrypt some data using RSA with symmetric keys. All I know about RSA is that it is used as an asymmetric key algorithm. I have searched for anything like that and find none. So is it possible? If yes, is there an java implementation (JCE provider) of it?
Thanks in advance.

带有对称密钥的 RSA 意味着 - 使用 RSA 建立对称密钥并随后使用该对称密钥。这就是 SSL 的工作原理...
RSA with symmetric key means - using RSA to establish a symmetric key and use that symmetric key afterwards. That is how SSL works...
您的客户端可能指的是基于 RSA 的密钥传输协议，使用 RSA 非对称密钥来“包装”对称密码的对称密钥，该对称密码将用于加密两个通信方之间的进一步消息。有关 RSA-KEM 的示例，请参阅 RFC5990。正如 Prabath 已经指出的那样，RSA 也常用于 SSL/TLS 中来交换对称密钥。
如果这不是他的意思，那么我会轻轻地忽略他，并尝试说服他，他应该将安全决策留给对材料有更好理解的人，因为不存在所谓的“安全决策”。对称 RSA 密钥。
What your client probably means is a Key Transport Protocol based on RSA, using the RSA asymmetric keys to "wrap" a symmetric key for a symmetric Cipher that would be used to encrypt further messages between the two communication parties. See RFC5990 for the example of RSA-KEM. As Prabath already pointed out, RSA is also commonly used in SSL/TLS for exchanging a symmetric key.
If that's not what he means, then I would gently ignore him and try to convince him that he should leave security decisions to people that have a better understanding of the material, because there is no such thing as a symmetric RSA key.
不，不是。建议他们 AES 就是他们想要的。
No it's not. Suggest them that AES is what they want.
