[cabfpub] LV Certificates

[Erwann Abalea]

Bonjour,

The concerned relying parties can only support TLS1.0 at most, certainly SSL3, probably SSL2, certainly not AES, mostly 3DES/RC2/RC4, only CBC mode, maybe DHE but probably only using standard groups, probably *-export cipher suites (the 40/512 junk category), no SNI, certainly a lot of TLS attacks and CBC failures.
This proposal hopes that the RP will perform revocation checks by OCSP, or maybe no revocation check at all.

All this for 2-7% of user agents, to be confirmed, with a promise that it will be solved by 2019, « I swear ».

Is this serious?


Cordialement,
Erwann Abalea

This is a draft ballot for review that will, of course, change based on the debate in the forum. Although CAs will stop issuing SHA-1 on 2016/1/1, there isn’t any reason these changes couldn’t go into effect in early January (assuming a passing vote).

The ballot also increases the resiliency of SHA1 certs against attacks by requiring higher entropy serial numbers.
