This is the inaugural issue of Cryptography Dispatches, meant to be quick, frequent and lightly edited discussions of cryptographic topics. Longer form can be found at blog.filippo.io.

For my first round, I am writing about the recent attack on the PGP keyservers. The overall goal of the newsletter is to explain cryptography rather than to comment on the news, so we will cover context and mechanics, not the last minute updates. Issues about Ristretto, Ed25519 in Go, AES-GCM-SIV, and OPRF based contact discovery are still coming as promised!
