Method Detail

setBlockCounter

void setBlockCounter(long block)

Sets the counter so that the block with the given index, starting at 0, can be processed next.

Parameters:

block - The index of the block, starting at 0, which will be processed next when BlockCipher.processBlock(byte[], int, byte[], int) is called.

getBlockCounter

long getBlockCounter()

Returns the index of the block, starting at 0, which will be processed next when BlockCipher.processBlock(byte[], int, byte[], int) is called.
