Merge branch 'mbedtls'
Replace Crypto++ 5.6.2 with Mbed TLS 3.6.0 Newer compilers are starting to show the age of the crypto library we've been using, as it is sometimes a pain to recompile compass lately. So, the tracked version of Crypto++ was at least due for an upgrade. However, I plan to soon begin reimplementing compass in C. So, I'm taking this opportunity to first just migrate the cryptography library to a newer C alternative. This branch does so, and integrates its use into the current C++ version of compass. * mbedtls: Remove unnecessary exception handler catch block Refactor random password generation to use mbedtls entropy source Refactor SHA256 function to use mbedtls Refactor AES functions to use mbedtls Add Mbedtls library Remove Crypto++ library
