Method Detail

encode

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

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

Parameters:

data - the byte array to encode

Returns:

a byte array containing the base 64 encoded data.

encode

public static int encode(byte[] data,
                         OutputStream out)
                  throws IOException

Encode the byte data to base 64 writing it to the given output stream.

Parameters:

data - the byte array to encode

out - the output stream where the result is to be written.

Returns:

the number of bytes produced.

Throws:

IOException - if the output stream throws one

encode

public static int encode(byte[] data,
                         int off,
                         int length,
                         OutputStream out)
                  throws IOException

Encode the byte data to base 64 writing it to the given output stream.

Parameters:

data - the byte array to encode

off - offset

length - length

out - OutputStream

Returns:

the number of bytes produced.

Throws:

IOException

decode

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

decode the base 64 encoded input data. It is assumed the input data is valid.

Parameters:

data - the byte array to encode

Returns:

a byte array representing the decoded data.

decode

public static byte[] decode(String data)

decode the base 64 encoded String data - whitespace will be ignored.

Parameters:

data - the byte array to encode

Returns:

a byte array representing the decoded data.

decode

public static int decode(String data,
                         OutputStream out)
                  throws IOException

decode the base 64 encoded String data writing it to the given output stream, whitespace characters will be ignored.

Parameters:

data - the data to decode

out - OutputStream

Returns:

the number of bytes produced.

Throws:

IOException - if an exception occurs while writing to the specified output stream
