Class Base64

public class Base64 extends Object

Provides Base64 encoding and decoding as defined by RFC 2045.

This class implements section 6.8. Base64 Content-Transfer-Encoding from RFC 2045 Multipurpose Internet Mail Extensions (MIME) Part One: Format of Internet Message Bodies by Freed and Borenstein.

Method Detail

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

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

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

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.

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

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
