Method Details
-
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
- iftrue
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
