== Extending the Tutorial ==
The previous tutorial is a basic attack on the core RSA algorithm. There are several extensions of it you can try. As mentioned you can improve the automatic key recover algorithm. You can also try performing this attack on longer key lengths -- this is made much easier with the ChipWhisperer-Pro, as it can use "streaming mode" to recover an extremely long key.
You can also try performing this attack on longer key lengths -- this is made much easier with the ChipWhisperer-Pro, as it can use "streaming mode" to recover an extremely long key, or even capture the entire RSA algorithm. The ChipWhisperer-Lite & Pro both have a "downsample" capability to fit a longer capture into your buffer. You may need an external low-pass filter in some cases. The ChipWhisperer-Pro has a unique analog trigger feature. This can also be used to break the RSA algorithm by simply performing the pattern match in real-time, and measuring the time delay of triggger trigger locations. This is demonstrated in the next section.
