/**
 * Convert binary data to and from UrlBase64 encoding.  This is identical to
 * Base64 encoding, except that the padding character is "." and the other 
 * non-alphanumeric characters are "-" and "_" instead of "+" and "/".
 * 

* The purpose of UrlBase64 encoding is to provide a compact encoding of binary * data that is safe for use as an URL parameter. Base64 encoding does not * produce encoded values that are safe for use in URLs, since "/" can be * interpreted as a path delimiter; "+" is the encoded form of a space; and * "=" is used to separate a name from the corresponding value in an URL * parameter. */ public class UrlBase64Encoder extends Base64Encoder { public UrlBase64Encoder() { encodingTable[encodingTable.length - 2] = (byte) '-'; encodingTable[encodingTable.length - 1] = (byte) '_'; padding = (byte) '.'; // we must re-create the decoding table with the new encoded values. initialiseDecodingTable(); } }
