  Parameters:
    `in` - an array containing the data bytes to be encoded.
  Returns:
    A character array with the Base64 encoded data.

### decode

    public static java.lang.String decode(java.lang.String s)

  Decodes a Base64 string.

  Parameters:
    `s` - a Base64 String to be decoded.
  Returns:
    A String containing the decoded data.
  Throws:
    `java.lang.IllegalArgumentException` - if the input is not valid Base64 encoded data.

### decode

    public static byte[] decode(char[] in)
