If info.MD5Sum contains base64 encoded hash can we rename it to MD5SumBase64? But I would like to store hex encoded values and encode/decode where it's need

For v0.29.0 we do compute both hashes, unless it produce significant slowdown. As for future releases, we may drop SHA and use MD5 as new default for everything.

Maybe we can introduce new section features or hashes instead of just md5?

Also we should add description of this param to docs/configuration.md and to config/config.env.

If we returns md5 as ETag why do we need to compute sha256? It seems we can just calculate md5 and save it as ETag (I mean use the same field in data.ObjectInfo, the same key in for tree node meta etc.)

	if md5Enabled && len(o.MD5Sum) > 0 {
		return o.MD5Sum
	}

	return o.HashSum

and then instead of aff675a8eb/api/handler/put.go (L331-L335)

we can write (we can extend interface with MD5Enabled() bool since appSettings implements it anyway )

w.Header().Set(api.ETag, objInfo.ETag(h.cfg.MD5Enable()))
