Class Base64Support

java.lang.Object
  net.shibboleth.utilities.java.support.codec.Base64Support

public final class Base64Support
extends Object

Helper class for working with Base64.

This helper class specifically addresses that waste of the Apache Codec encode/decode static methods creating new instances of the Base64 for every operation. It also provides the helper method to produce both chunked and unchunked encoded content as strings.

Field Summary

static boolean	CHUNKED Chunk the encoded data into 76-character lines broken by CRLF characters.
private static org.apache.commons.codec.binary.Base64	CHUNKED_ENCODER Encoder used to produce chunked output.
static boolean	UNCHUNKED Do not chunk encoded data.
private static org.apache.commons.codec.binary.Base64	UNCHUNKED_ENCODER Encoder used to produce unchunked output.

Constructor Summary

private

Base64Support() Constructor.

Method Summary

static byte[]	decode(String data) Decodes (un)chunked Base64 encoded data.
static String	encode(byte[] data, boolean chunked) Base64 encodes the given binary data.

Method Detail

encode

@Nonnull
public static String encode(@Nonnull
                                    byte[] data,
                                    boolean chunked)

Base64 encodes the given binary data.

Parameters:

data - data to encode

chunked - whether the encoded data should be chunked or not

Returns:

the base64 encoded data

decode

@Nonnull
public static byte[] decode(@Nonnull
                                    String data)

Decodes (un)chunked Base64 encoded data.

Parameters:

data - Base64 encoded data

Returns:

the decoded data
