8.9 KEY EXERCISES

EXERCISE 8.9: KEY EXERCISES

Try re-creating TLS’s key transport and key agreement operations. Let’s start with key transport. Start by taking one of the RSA certificates you’ve generated. If you were a browser, this is what you would receive over the wire. Create a Python program to import the certificate, extract the RSA public key, and use it to encrypt some random bytes (i.e. like a key) that you write back to disk.

There were already exercises in Chapter 6 for key agreement, even over a network. If you didn’t do those exercises, then maybe try it again now.
