    I'm trying to fight fires as the IETF is writing requisition orders for gasoline and being snarky about it: https://www.ietf.org/mail-archive/web/tls/current/msg16620.html …

        @bascule To be fair, it does seem like you're missing a bit about how the spec works :) Subtleties about here

        @bascule +=Supports,C=Client, S=Server. C(+)&S(-) - S shouldn't configure DHE, period. C(-)&S(+) - S's TLS lib should know to select !DHE

        @sleevi_ the real-world problem is humans saw Logjam and are trying to actively harden DHE cuz a scary branded vuln said so...

        @bascule @sleevi_ No, the real-world problem is Java having a limit on the strength of DH parameters and not supporting EC in v6.

        @ivanristic @sleevi_ Logjam was a "branded" vuln that got people scared about weak DH groups except they didn't understand what they'd break

        @ivanristic @sleevi_ the thing that's driving me insane is it's breaking TLS handshakes for clients that WOULD NEGOTIATE ECDHE OTHERWISE

        @ivanristic @sleevi_ in an effort to shore up a legacy solution, we're breaking clients that wouldn't use the legacy solution anyway

        @bascule just because Java sucks doesn't mean that FF-DHE is a bad idea :)

        @a_z_e_t it's slow, it has large keys, and it has sharp edges. That's why it sucks. And... keeping it around is breaking things

        @a_z_e_t but hey, let's make TLS more complicated by doubling down on features that nobody uses!

        @bascule actually a lot of sites still use it. and its the only fallback if somerhing in the ECC stack breaks.

        @a_z_e_t I not only called that argument out in advance in my first message but it’s wrong. There’s still RSA

        @a_z_e_t I’m not a fan of RSA for key exchange, but it *is* a backup in the event of an ECC-specific disaster
