OpenSSL: CVE-2004-2761 replace MD5 hash algorithm

OpenSSL: CVE-2004-2761 replace MD5 hash algorithm

Use SHA256 as default digest for OpenSSL instead of MD5.

CVE: CVE-2004-2761

    The MD5 Message-Digest Algorithm is not collision resistant,
    which makes it easier for context-dependent attackers to
    conduct spoofing attacks, as demonstrated by attacks on the
    use of MD5 in the signature algorithm of an X.509 certificate.

Upstream-Status: Backport
