                                            int len,
                                            java.lang.StringBuffer buf)

Encodes the part of the given byte array denoted by start and len to the Base64 format. The encoded data is appended to the given StringBuffer. If no StringBuffer is given, a new one is created automatically. The StringBuffer is the return value of this method.

Parameters:

data -

start -

len -

buf -

Returns:

Encoded string

decode

static int decode(char c)

decode

public static byte[] decode(java.lang.String s)
