Method Detail

encodeBytes

public static String encodeBytes(byte[] source)

Encodes a byte array into Base64 notation.

Parameters:

source - The data to convert

Returns:

encoded base64 representation of source.

encodeBytes

public static String encodeBytes(byte[] source,
                                 int off,
                                 int len)

Encodes a byte array into Base64 notation.

Parameters:

source - The data to convert

off - Offset in array where conversion should begin

len - Length of data to convert

Returns:

encoded base64 representation of source.

decode

public static byte[] decode(byte[] source,
                            int off,
                            int len)

Low-level decoding ASCII characters from a byte array.

Parameters:

source - The Base64 encoded data

off - The offset of where to begin decoding

len - The length of characters to decode

Returns:

decoded data

Throws:

IllegalArgumentException - the input is not a valid Base64 sequence.

decode

public static byte[] decode(String s)

Decodes data from Base64 notation.

Parameters:

s - the string to decode

Returns:

the decoded data
