See Matt's prototype for an example.

Questions to answer:

• Do we use aws-lc as the underlying crypto library instead of libcrypto?
• does it have implications for Atlas Gov? See <https://docs.google.com/document/d/1xSftzEPPpk6As_oA0QPyGMnDg4pKg_7LLwPWMCnd4o0/edit?disco=AAAB7LJ8kzg>
• can/should aws-lc be vendored if we use it, or rely on a deployed shared library?
