摘要：
In the digital image of each pixel consists of three components, namely R, G, and B. If the three components are combined in a block then the block will have data with 24 bit or three characters. By default shortage of bits in each block will be filled by the next bit of the pixel so that each block will have the appropriate size is 32bit. The problem that happens is if the number of pixels is not in accordance with the division so it is necessary to block or adding padding bit 0 in register block, if padding occurs then the encrypted data size will change that affects the size of the image will change and will be hard pressed in preparing the return data encryption results in the form of images.
