public class B64Code
extends java.lang.Object
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 java.lang.String encode(java.lang.String s)
Does not insert whitespace as described in RFC 1521.
s
- String to encode.public static java.lang.String encode(java.lang.String s, java.lang.String charEncoding)
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.public static java.lang.String encode(java.lang.String s, java.nio.charset.Charset charEncoding)
Does not insert whitespace as described in RFC 1521.
s
- String to encode.charEncoding
- The character encoding of the provided input String.public 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 CRLFpublic static java.lang.String decode(java.lang.String encoded, java.lang.String charEncoding)
Unlike decode(char[])
, extra whitespace is ignored.

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.
