Base64Codec

public Base64Codec()
Method Detail

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.
