def b64len(b64str):
    """
    Calculate the length in bytes of a base64 string.

    This function could decode the base64 string to a binary blob and count its
    number of bytes with len(). But, that's inefficient and requires more
    memory that really needed.

    Base64 encodes three bytes to four characters. Sometimes, padding is added
    in the form of one or two '=' characters.
