python+encryption：使用公钥加密会话密钥-python+encryption:Encryptingsessionkeyusingpublickey

There's also the PyCrypto module that looks exactly like what you are looking for: http://www.dlitz.net/software/pycrypto/ the API docs are here: http://www.dlitz.net/software/pycrypto/apidoc/ and some nice docs with basic examples of encrypting/decrypting here: http://www.dlitz.net/software/pycrypto/doc/.

还有PyCrypto模块看起来与您正在寻找的完全相同:http://www.dlitz.net/software/pycrypto/ API文档在这里:http://www.dlitz.net/software/pycrypto/apidoc /和一些很好的文档,其中包含加密/解密的基本示例:http://www.dlitz.net/software/pycrypto/doc/。

I'll confess I haven't used this module, but it seems like you would establish a session with a public key, then use that to encrypt/decrypt the channel with a Crypto.PublicKey object. Then do the usual activity of generating a session key, communicating that over whatever channel you have. Finally, switch the channel to a Crypto.Cipher object using the session key.

我承认我没有使用过这个模块,但似乎你要用公钥建立会话,然后使用它来加密/解密使用Crypto.PublicKey对象的通道。然后执行生成会话密钥的常规活动,通过您拥有的任何渠道进行通信。最后,使用会话密钥将通道切换到Crypto.Cipher对象。

Also, be sure to be very, very careful about how you obtain the value for your session key if security is a real concern, particularly on multiuser or only partially trusted machine.

此外,如果安全性是一个真正的问题,请确保非常非常小心如何获取会话密钥的值,尤其是在多用户或仅部分受信任的计算机上。

See this post for background information about the basic technology. That post is about encryption in general - for information about using gpg from Python, see this, for example.

有关基本技术的背景信息,请参阅此文章。该帖子一般是关于加密的 - 有关使用Python的gpg的信息,请参阅此示例。

See What is the best/easiest to use encryption library in python, which mentions a PGP-compatible solution, gpgme.

请参阅python中最好/最容易使用的加密库是什么,它提到了与PGP兼容的解决方案gpgme。

For reasons I ignore, nobody in How to do PGP in Python (generate keys, encrypt/decrypt) mentioned gpgme...

由于我忽略的原因,没有人在如何做Python中的PGP(生成密钥,加密/解密)提到gpgme ...
