Class Base64Codec

java.lang.Object
  com.novell.xml.util.Base64Codec

public class Base64Codec

extends Object

Collection of simple static methods for encoding/decoding binary data as base 64 encoded information. These methods are implemented in terms of com.novell.java.io.Base64InputStream and com.novell.io.Base64OutputStream.

If encoding/decoding from to/from streams rather than strings it will be more efficient to use the Base64InputStream/Base64OutputStream classes.
