Examples of org.bouncycastle2.crypto.BlockCipher.processBlock()

org.bouncycastle2.crypto.BlockCipher.processBlock()
Process one block of input from the array in and write it to the out array. @param in the array containing the input data. @param inOff offset into the in array the data starts at. @param out the array the output data will be copied into. @param outOff the offset into the out array the output will start at. @exception DataLengthException if there isn't enough data in in, orspace in out. @exception IllegalStateException if the cipher isn't initialised. @return the number of bytes processed and produced.
