java.lang.Objectorg.eclipse.jetty.util.B64Code
public class B64Code
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.

public static String encode(String s)
Does not insert whitespace as described in RFC 1521.
s - String to encode.
public static String encode(String s,
String charEncoding)
throws UnsupportedEncodingException
Does not insert whitespace as described in RFC 1521.
s - String to encode.charEncoding - String representing the name of
the character encoding of the provided input String.
UnsupportedEncodingExceptionpublic static char[] encode(byte[] b)
Does not insert whitespace as described in RFC 1521.
Avoids creating extra copies of the input/output.
b - byte array to encode.
public static char[] encode(byte[] b,
boolean rfc2045)
Does not insert whitespace as described in RFC 1521, unless rfc2045 is passed as true.
Avoids creating extra copies of the input/output.
b - byte array to encode.rfc2045 - If true, break lines at 76 characters with CRLF
public static String decode(String encoded,
String charEncoding)
throws UnsupportedEncodingException
Unlike decode(char[]), extra whitespace is ignored.
encoded - String to decode.charEncoding - String representing the character encoding
used to map the decoded bytes into a String.
UnsupportedEncodingException - if the encoding is not supported
IllegalArgumentException - if the input is not a valid
B64 encoding.public static byte[] decode(char[] b)
Unlike other decode methods, this does not attempt to cope with extra whitespace as described in RFC 1521/2045.
Avoids creating extra copies of the input/output.
Note this code has been flattened for performance.
b - char array to decode.
IllegalArgumentException - if the input is not a valid
B64 encoding.public static byte[] decode(String encoded)
Unlike decode(char[]), extra whitespace is ignored.
encoded - String to decode.
IllegalArgumentException - if the input is not a valid
B64 encoding.
