More and more CAs (also internal ones, possibly most commonly used with logstash-forwarder) are using certificates signed using SHA256 or SHA512, whereas go's X.509 support by default only supports certificates signed with a SHA1 hash.
This leads to logstash-forwarder failing with
The error message isn't very helpful and even if users were capable of easily finding out where the problem is, you can't expect a CA to provide their certificate signed with a different hash, so IMHO these newer certificates should be supported.
Thankfully, supporting them is reduced to importing the two hash functions before connecting.
