My opinion is that security by RFC is not security, it's mommy medicine. Standards have had a terrible time keeping up with security realities. NITS's curves leak side channel information all over the place. I don't have details on what implementations are set to calculate the NIST curves in constant time, and that's not an easy feat to do anyway so I don't want to depend

I am interested in configuring Dovecot's TLS so as to retain forward secrecy, but eliminate all of NIST's elliptic curves. Besides being subject to side channel attacks [1], in some quarters there is a general distrust of NIST's curves and any of their other cryptographic primitives after the Dual EC DRBG debacle. >From what I can tell, the following will prevent the use of
