Continues a multiple-part encryption or decryption operation (depending on how this cipher was initialized), processing another data part.

The first inputLen bytes in the input buffer, starting at inputOffset inclusive, are processed, and the result is stored in the output buffer, starting at outputOffset inclusive.

If the output buffer is too small to hold the result, a ShortBufferException is thrown.

Parameters:

input		the input buffer
inputOffset		the offset in input where the input starts
inputLen		the input length
output		the buffer for the result
outputOffset		the offset in output where the result is stored

Returns:  the number of bytes stored in output

Exceptions:

ShortBufferException

if the given output buffer is too small to hold the result
