    • 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)
      Decodes Base64 data into octects
      Parameters:
      base64Data - Byte array containing Base64 data
      Returns:
      Array containing decoded data.
