      Manually check whether the string contains only the characters (A-Z, a-z, , 0-9, + and /) that can be the output of Base64 encoding. Such a string can be successfully decoded. :cool:

        1. Check if the length is an exact multiple of 4. 2. Try to decode it and catch any error.

        Best wishes, Hans

              Can't understand why someone downvoted this.
