public Base64()

方法详细资料

isArrayByteBase64

public static boolean isArrayByteBase64(byte[] arrayOctect)

Tests a given byte array to see if it contains only valid characters within the Base64 alphabet.

参数:

arrayOctect - byte array to test

返回:

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.

参数:

binaryData - binary data to encode

返回:

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

参数:

binaryData - binary data to encode

返回:

Base64 characters chunked in 76 character blocks

decode

public static byte[] decode(byte[] pArray)

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

参数:

pArray - A byte array containing Base64 character data

返回:

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.

参数:

binaryData - Array containing binary data to encode.

isChunked - if isChunked is true this encoder will chunk the base64 output into 76 character blocks

返回:

Base64-encoded data.

decodeBase64

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

Decodes Base64 data into octects

参数:

base64Data - Byte array containing Base64 data

返回:

Array containing decoded data.

encode

public static byte[] encode(byte[] pArray)

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

参数:

pArray - a byte array containing binary data

返回:

A byte array containing only Base64 character data

decode

public static String decode(String cryptoStr)
                     throws UnsupportedEncodingException

抛出:

UnsupportedEncodingException

decode2

public static byte[] decode2(String encoded)

Decodes Base64 data into octects

参数:

encoded - string containing Base64 data

返回:

Array containind decoded data.
