B64Code

public class B64Code (Code)

Fast B64 Encoder/Decoder as described in RFC 1421.

Does not insert or interpret whitespace as described in RFC 1521. If you require this you must pre/post process your data.

Note that in a web context the usual case is to not want linebreaks or other white space in the encoded output.

Method Summary
public static String	decode(String s) Base 64 decode as described in RFC 1421.
public static String	decode(String s, String charEncoding) Base 64 decode as described in RFC 1421. Does not attempt to cope with extra whitespace as described in RFC 1521. Parameters: s - String to decode Parameters: charEncoding - String representing the character encodingused to map the decoded bytes into a String.
public static byte[]	decode(char[] b) Fast Base 64 decode as described in RFC 1421. Does not attempt to cope with extra whitespace as described in RFC 1521. Avoids creating extra copies of the input/output. Note this code has been flattened for performance. Parameters: b - char array to decode.
