Method Detail

encode

public static String encode(byte[] data)

Converts a byte array into a Base64 encoded string.

Parameters:

data - bytes to encode.

Returns:

base64 encoding of data; 4 chars for every 3 bytes.

encode

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

Converts a byte array into a Base64 encoded string.

Parameters:

data - bytes to encode.

offset - which byte to start at.

length - how many bytes to encode; padding will be added if needed.

Returns:

base64 encoding of data; 4 chars for every 3 bytes.

decode

public static byte[] decode(String encoded)
                     throws IOException

Converts a Base64 encoded string to a byte array.

Parameters:

encoded - Base64 encoded data.

Returns:

decode binary data; 3 bytes for every 4 chars - minus padding.

Throws:

IOException - if an I/O error occurs reading the data.

decode

public static byte[] decode(String encoded,
                            int offset,
                            int length)
                     throws IOException

Converts an embedded Base64 encoded string to a byte array.

Parameters:

encoded - a String with Base64 data embedded in it.

offset - which char of the String to start at.

length - how many chars to decode; must be a multiple of 4.

Returns:

decode binary data; 3 bytes for every 4 chars - minus padding.

Throws:

IOException - if an I/O error occurs reading the data.
