Class AbstractBase64Encoder

java.lang.Object

org.antfarmer.ejce.encoder.AbstractBase64Encoder

All Implemented Interfaces:

TextEncoder

Direct Known Subclasses:

AbstractBase64UrlEncoder, Base64Encoder, Base64PaddedEncoder

public abstract class AbstractBase64Encoder
extends Object
implements TextEncoder

Abstract encoder for encoding/decoding bytes and text using the Base-64 format. The character set includes: [A-Za-z0-9+/]. This format results in a 33% increase in output length at best. This class is thread-safe.
