[openssl-dev] Disablement of insecure hashes for digital signatures

Just a notice for anyone interested,

In Red Hat Enterprise Linux 6 and 7 we disabled support for insecure
hashes for digital signatures. Basically signatures with MD5, MD4, MD2,
and SHA0 will fail verification by default. We could not switch off the
support for these weak hash algorithms completely due to possible
legacy uses so we at least switched it off for signature verification.
