Unmarshaller on []byte field

[yinebebt]

Does Viper support unmarshalling a Base64 string value into []byte? I mean like the json/encoding unmarshaller do.
For example, if I have a struct: type config struct { Salt []byte } can Viper unmarshal a configuration like salt: <base64-encoded-string> directly into the Salt field?

You could implement that by introducing a custom type using mapstructure.
