Given this, having a robust monitoring system in place for FBCrypto has been instrumental in ensuring its reliability as well as in helping our engineers understand how cryptography is used at Meta so they can make informed development decisions. Our logging initially created a unique row in the buffered logger for every derived keyset, which used a lot of space and put increased load on backend data stores. This work could not have been accomplished without the critical efforts of numerous folks, particularly Grace Wu, Ilya Maykov, Isaac Elbaz, and the rest of the CryptoEng team at Meta.
