{"The input is not a valid Base-64 string as it contains a non-base 64 character,

more than two padding characters, or an illegal character among the padding characters."}

    as there are only 64 characters in Base64 charset (A-Z,a-z,0-9,+,/) plus the pad char "=". it should be easy to determine the error:

    https://en.wikipedia.org/wiki/Base64

    the length of the unencoded byte array should be a multiple of 3, otherwise padding is required. each char encodes 6 bits.
