I would like to make !cryptography@lemmy.ml in to a community about cryptography (as in communications security).

All of the links currently there are on this topic, but the description is unfortunately “Useful and interesting content about bitcoin and cryptocurrency” and the existing mod appears to no longer be active.

FWIW there are already several other communities about cryptocurrency, including !bitcoin@lemmy.ml, !bitcoin_crypto@lemmy.ml, !cryptocurrency@lemmy.ml, !cryptocurrencies@lemmy.ml, !cryptoassets@lemmy.ml, and !crypto@lemmy.ml.
