getOutputSizeForFinal
int getOutputSizeForFinal(int inputLen)
Description copied from class:OpenSSLCipher
The size of output ifdoFinal()
is called with thisinputLen
. If padding is enabled and the size of the input puts it right at the block size, it will add another block for the padding.- Overrides:
