Method Detail

encodeBase64

public static char[] encodeBase64(byte[] data)

Encodes the passed byte array using the base64 rules. The base64 encoding schema is performed by grouping the bytes in to 6-bit quantities and then encoding them.

For more information see RFC1341 for the format used for base64 encoding.

Parameters:

data - The input byte array

Returns:

The converted data in a character stream.

decodeBase64

public static byte[] decodeBase64(char[] data)

Decodes a character array into the corresponding byte array. The buffer must be an intergral number of 4 character. I.E. size mod 4 is equal to zero or an exception will be thrown. Likewise, if there is an invalid character in the input array then an exception will be thrown.

Parameters:

data - The data stream to be filtered.

Returns:

The coverted array of bytes.

Throws:

IllegalArgumentException - Thrown if an invalid buffer that cannot be decoded is passed.
