Method Detail

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 or null for null result

Returns:

byte[] containing Base64 characters in their UTF-8 representation or null for null input

encodeBase64String

public static String encodeBase64String(byte[] binaryData)

Encodes binary data using the base64 algorithm but does not chunk the output.

Parameters:

binaryData - binary data to encode or null for null result

Returns:

String containing Base64 characters or null for null input

encodeBase64URLSafe

public static byte[] encodeBase64URLSafe(byte[] binaryData)

Encodes binary data using a URL-safe variation of the base64 algorithm but does not chunk the output. The url-safe variation emits - and _ instead of + and / characters.

Parameters:

binaryData - binary data to encode or null for null result

Returns:

byte[] containing Base64 characters in their UTF-8 representation or null for null input

encodeBase64URLSafeString

public static String encodeBase64URLSafeString(byte[] binaryData)

Encodes binary data using a URL-safe variation of the base64 algorithm but does not chunk the output. The url-safe variation emits - and _ instead of + and / characters.

Parameters:

binaryData - binary data to encode or null for null result

Returns:

String containing Base64 characters or null for null input

decodeBase64

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

Decodes Base64 data into octets. Note that this method handles both URL-safe and non-URL-safe base 64 encoded inputs.

Parameters:

base64Data - Byte array containing Base64 data or null for null result

Returns:

Array containing decoded data or null for null input

decodeBase64

public static byte[] decodeBase64(String base64String)

Decodes a Base64 String into octets. Note that this method handles both URL-safe and non-URL-safe base 64 encoded strings.

Parameters:

base64String - String containing Base64 data or null for null result

Returns:

Array containing decoded data or null for null input
