Class Base64Url

java.lang.Object

co.codewizards.cloudstore.core.util.Base64Url

public class Base64Url
extends Object

Standard base64url (RFC 4648) encoding and decoding.

The difference to normal base64 is that base64url replaces '+' by '-' and '/' by '_' in order to make the encoded string usable in URLs and file names without any escaping.

This class is an adjusted version of org.apache.commons.codec.binary.Base64. Thanks to the Apache Software Foundation!

Method Detail

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

encodeBase64ToString

public static String encodeBase64ToString(byte[] binaryData)

encodeBase64

public static byte[] encodeBase64(byte[] binaryData)

Encodes binary data using the base64url algorithm.

Parameters:

binaryData - Array containing binary data to encode.

Returns:

Base64-encoded data.

decodeBase64FromString

public static byte[] decodeBase64FromString(String base64String)

decodeBase64

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

Decodes Base64 data into octects

Parameters:

base64Data - Byte array containing Base64 data

Returns:

Array containing decoded data.
