Remove ECC-GOST (GOST R 34.11-94) support
ECC-GOST (GOST R 34.11-94) has been superseded by GOST R 34.11-2012 in [RFC6986]. The GOST R 34.11-2012 hasn't been standardized for use in DNSSEC.
GOST R 34.11-94 is superseded by GOST R 34.11-2012 from 1st January 2013. That means that all new systems that are presented for certification MUST use GOST R 34.11-2012 and MAY use GOST R 34.11-94 also for maintaining compatibility with existing systems. Usage of GOST R 34.11-94 in current systems is allowed at least for a 5-year period.
From OpenSSL 1.1.0 ChangeLog:
*) The GOST engine was out of date and therefore it has been removed. An up to date GOST engine is now being maintained in an external repository. See: https://wiki.openssl.org/index.php/Binaries. Libssl still retains support for GOST ciphersuites (these are only activated if a GOST engine is present).
Given the very low deployment numbers (SecSpider reports 119 keys and that's less than DSA), I propose to remove this ciphersuite from BIND.
