static byte[] |
decode(byte[] base64Data)
Decodes Base64 data into octets
|
static byte[] |
decode(String base64Encoded)
Converts the specified UTF-8 Base64 encoded String and decodes it to a raw Base64 decoded byte array.
|
static String |
decodeToString(byte[] base64Encoded)
Decodes the specified Base64 encoded byte array and returns the decoded result as a UTF-8 encoded.
|
static String |
decodeToString(String base64Encoded)
Converts the specified UTF-8 Base64 encoded String and decodes it to a resultant UTF-8 encoded string.
|
static byte[] |
encode(byte[] pArray)
Encodes a byte[] containing binary data, into a byte[] containing characters in the Base64 alphabet.
|
static byte[] |
encode(byte[] binaryData,
boolean isChunked)
Encodes binary data using the base64 algorithm, optionally chunking the output into 76 character blocks.
|
static byte[] |
encodeChunked(byte[] binaryData)
Encodes binary data using the base64 algorithm and chunks the encoded output into 76 character blocks
|
static String |
encodeToString(byte[] bytes)
Base64 encodes the specified byte array and then encodes it as a String using Shiro's preferred character
encoding (UTF-8).
|
static boolean |
isBase64(byte[] arrayOctect)
Tests a given byte array to see if it contains only valid characters within the Base64 alphabet.
