Little insight would be great please.

Answer 1

DecodedLen returns the maximal length.

This length is useful for sizing your buffer but part of the buffer won't be written and thus won't be valid UTF-8.

You have to use only the real written length returned by the Decode function.

l, _ := base64.StdEncoding.Decode(base64Text, []byte(message))
log.Printf("base64: %s\n", base64Text[:l])
