Method Detail

encode

public static String encode(String s)

base-64 encode a string

Parameters:

s - The ascii string to encode

Returns:

The base64 encoded result

encode

public static String encode(byte[] src)

base-64 encode a byte array

Parameters:

src - The byte array to encode

Returns:

The base64 encoded result

encode

public static String encode(byte[] src,
                            int start,
                            int length)

base-64 encode a byte array

Parameters:

src - The byte array to encode

start - The starting index

length - The number of bytes

Returns:

The base64 encoded result

decode

public static byte[] decode(String s)

A Base64 decoder. This implementation is slow, and doesn't handle wrapped lines. The output is undefined if there are errors in the input.

Parameters:

s - a Base64 encoded string

Returns:

The byte array eith the decoded result

main

public static void main(String[] args)

Test the decoder and encoder. Call as Base64 [string].
