Class Base32Support

java.lang.Object

net.shibboleth.idp.saml.nameid.impl.Base32Support

public final class Base32Support
extends Object

Helper class for working with Base32.

This helper class specifically addresses that waste of the Apache Codec encode/decode static methods creating new instances of the Base32 for every operation. It also provides the helper method to produce both chunked and unchunked encoded content as strings.

This is present solely to avoid requiring a bump to java-support for this patch version.

Since:

3.3.2
