 `cryptomite` is a modular, extensible high-level Python library 
 for randomness extractions, created by Quantinuum's Quantum Cryptography team. 
 At a high level, the library offers state-of-the-art randomness extractors that are easy to use, optimized and numerically precise
-providing a trade-off of features that suits numerous practical use cases.
