Encodes and decodes to and from Base64 notation.
- *Homepage: http://iharder.net/base64.
- * - *The options parameter, which appears in a few places, is used to pass - * several pieces of information to the encoder. In the "higher level" methods such as - * encodeBytes( bytes, options ) the options parameter can be used to indicate such - * things as first gzipping the bytes before encoding them, not inserting linefeeds - * (though that breaks strict Base64 compatibility), and encoding using the URL-safe - * and Ordered dialects.
- * - *The constants defined in Base64 can be OR-ed together to combine options, so you - * might make a call like this:
- * - *String encoded = Base64.encodeBytes( mybytes, Base64.GZIP | Base64.DONT_BREAK_LINES );
- *
- * to compress the data before encoding it and then making the output have no newline characters.
- * - * - *- * Change Log: - *
- *- * I am placing this code in the Public Domain. Do with it as you will. - * This software comes with no guarantees or warranties but with - * plenty of well-wishing instead! - * Please visit http://iharder.net/base64 - * periodically to check for updates or to contribute improvements. - *
