UUENCODE includes a filename where BASE64 does not. + * The spec is described in RFC 2045. Base64 is a scheme where + * 3 bytes are concatenated, then split to form 4 groups of 6-bits each; and + * each 6-bits gets translated to an encoded printable ASCII character, via a + * table lookup. An encoded string is therefore longer than the original by + * about 1/3. The "=" character is used to pad the end. Base64 is used, + * among other things, to encode the user:password string in an + * Authorization: header for HTTP. Don't confuse Base64 with + * x-www-form-urlencoded which is handled by + * Java.net.URLEncoder.encode/decode + * If you don't like this code, there is another implementation at http://www.ruffboy.com/download.htm + * Sun has an undocumented method called sun.misc.Base64Encoder.encode. + * You could use hex, simpler to code, but not as compact. + *
+ * If you wanted to encode a giant file, you could do it in large chunks that + * are even multiples of 3 bytes, except for the last chunk, and append the outputs. + *
+ * To encode a string, rather than binary data java.net.URLEncoder may be better. See + * printable characters in the Java glossary for a discussion of the differences. + *
