Constructor Summary

Base64()

Method Summary

byte[]	decode(byte[] pArray) Decodes a byte[] containing containing characters in the Base64 alphabet.
static byte[]	decodeBase64(byte[] base64Data) Decodes Base64 data into octects
byte[]	encode(byte[] pArray) Encodes a byte[] containing binary data, into a byte[] containing characters in the Base64 alphabet.
static byte[]	encodeBase64(byte[] binaryData) Encodes binary data using the base64 algorithm but does not chunk the output.
static byte[]	encodeBase64(byte[] binaryData, boolean isChunked) Encodes binary data using the base64 algorithm, optionally chunking the output into 76 character blocks.
static byte[]	encodeBase64Chunked(byte[] binaryData) Encodes binary data using the base64 algorithm and chunks the encoded output into 76 character blocks
static boolean	isArrayByteBase64(byte[] arrayOctect) Tests a given byte array to see if it contains only valid characters within the Base64 alphabet.

public Base64()

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

decode

public byte[] decode(byte[] pArray)

Decodes a byte[] containing containing characters in the Base64 alphabet.

Parameters:

pArray - A byte array containing Base64 character data

Returns:

a byte array containing binary data

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 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.

encode

public byte[] encode(byte[] pArray)

Encodes a byte[] containing binary data, into a byte[] containing characters in the Base64 alphabet.

Parameters:

pArray - a byte array containing binary data

Returns:

A byte array containing only Base64 character data
