Method Detail

encode

public static java.lang.String encode(java.lang.String string)

Parameters:

string -

Returns:

the input string encoded using Base 64 encoding.

encode

public static java.lang.String encode(byte[] data)

encode

public static java.lang.StringBuilder encode(byte[] data,
                                             int start,
                                             int len,
                                             java.lang.StringBuilder 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 StringBuilder. If no StringBuilder is given, a new one is created automatically. The StringBuilder is the return value of this method.

decode

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

Decodes the given Base64 encoded String to a new byte array. The byte array holding the decoded data is returned.
