Method Detail

encode

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

Encodes binary data to a Base64 encoded characters.

Parameters:

data - the array of bytes to encode

Returns:

base64-coded character array.

decode

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

Decodes a BASE-64 encoded stream to recover the original data. White space before and after will be trimmed away, but no other manipulation of the input will be performed. As of version 1.2 this method will properly handle input containing junk characters (newlines and the like) rather than throwing an error. It does this by pre-parsing the input and generating from that a count of VALID input characters.

Parameters:

data - data to decode.

Returns:

the decoded binary data.
