byte[] | decode(byte[] pArray) - Decodes a byte[] containing containing
characters in the Base64 alphabet.

decode
public byte[] decode(byte[] pArray)
Decodes a byte[] containing containing
characters in the Base64 alphabet.
pArray
- A byte array containing Base64 character data
- a byte array containing binary data
decodeBase64
public static byte[] decodeBase64(byte[] base64Data)
Decodes Base64 data into octects
base64Data
- Byte array containing Base64 data
- 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.
pArray
- a byte array containing binary data
- 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.
binaryData
- binary data to encode
encodeBase64
public static byte[] encodeBase64(byte[] binaryData,
boolean isChunked)
Encodes binary data using the base64 algorithm, optionally
chunking the output into 76 character blocks.
binaryData
- Array containing binary data to encode.isChunked
- if true
this encoder will chunk
the base64 output into 76 character blocks
encodeBase64Chunked
public static byte[] encodeBase64Chunked(byte[] binaryData)
Encodes binary data using the base64 algorithm and chunks
the encoded output into 76 character blocks
binaryData
- binary data to encode
- 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.
arrayOctect
- byte array to test
true
if all bytes are valid characters in the Base64
alphabet or if the byte array is empty; false, otherwise
