Cryptography Dispatches

Cryptography Dispatches

Filippo Valsorda (@FiloSottile)’s lightly edited newsletter on cryptography engineering.

Cryptography Dispatches is not about what happened this month, but about

things that are good (Dispatch #4: OpenSSH 8.2 Just Works with Security Keys)
things that are bad (Dispatch #6: DSA Is Past Its Prime)
the occasional math (Dispatch #11: Re-Deriving the edwards25519 Decoding Formulas)
technical deep dives (Dispatch #2: The Linux CSPRNG Is Now Good!)
engineering design principles (Dispatch #10: Reconstruct Instead of Validating)
and of course opinions (Dispatch #8: Registries Considered Harmful, Dispatch #7: Replace PGP With an HTTPS Form, Dispatch #9: NaCl Is Not a High-Level API)

The newsletter comes without any tracking, so I rely on your replies to know if you’re reading it and if you’re enjoying it!
