      • isArrayByteBase64

        public static boolean isArrayByteBase64​(byte[] arrayOctect)
        Tests a given byte array to see if it contains only valid characters within the Base64 alphabet.
        Parameters:
        arrayOctect - byte array to test
        Returns:
        true if all bytes are valid characters in the Base64 alphabet or if the byte array is empty; false, otherwise

      • encodeBase64

        public static byte[] encodeBase64​(byte[] binaryData)
        Encodes binary data using the base64 algorithm but does not chunk the output.
        Parameters:
        binaryData - binary data to encode
        Returns:
        Base64 characters

      • encodeBase64Chunked

        public static byte[] encodeBase64Chunked​(byte[] binaryData)
        Encodes binary data using the base64 algorithm and chunks the encoded output into 76 character blocks
        Parameters:
        binaryData - binary data to encode
        Returns:
        Base64 characters chunked in 76 character blocks

      • encodeBase64

        public static byte[] encodeBase64​(byte[] binaryData,
                                  boolean isChunked)
        Encodes binary data using the base64 algorithm, optionally chunking the output into 76 character blocks.
        Parameters:
        binaryData - Array containing binary data to encode.
        isChunked - if isChunked is true this encoder will chunk the base64 output into 76 character blocks
        Returns:
        Base64-encoded data.

      • decodeBase64

        public static byte[] decodeBase64​(byte[] base64Data)

        Parameters:
        base64Data - Byte array containing Base64 data
        Returns:
        Array containing decoded data.
