%In Section~\ref{sec:aescorrectattempt}, we wrote down the below Cryptol theorem stating that our AES\indAES encryption/decryption functions work correctly:
%\begin{Verbatim}
% theorem AESCorrect: {msg key}. aesDecrypt (aesEncrypt (msg, key), key) == msg;
%\end{Verbatim}
% However, we were not able to do an automated proof of this fact, as it is beyond the scope of what SAT-based equivalence checkers can handle. In this
% section we will use our new tools to attack this problem and actually complete the proof in a reasonable amount of time.

%%%% Solutions
\chapter{Solutions to selected exercises}
As with any language, there are usually multiple ways to write the same
function in Cryptol. We have tried to use the most idiomatic
Cryptol code segments in our solutions. Note that Cryptol prints
numbers out in hexadecimal by default. In most of the answers below, we
have implicitly used the command {\tt :set base=10} to print numbers
out in decimal for readability.\indSettingBase
