Method Detail

encode

public static byte[] encode(byte[] data)

encode the input data producing a base 64 encoded byte array.

Returns:

a byte array containing the base 64 encoded data.

encode

public static byte[] encode(byte[] data,
                            int offset,
                            int length)

encode the input data producing a base 64 encoded byte array.

Parameters:

data - The data array to encode.

offset - The starting offset within the data array.

length - The length of the data to encode.

Returns:

a byte array containing the base 64 encoded data.
