For the server running the error, the state machine into the CON_STATE_ERROR state. Common causes of error: the client is disconnected from the client in advance. For example, you don't stop brush...

AES encryption algorithm

U014427391
AES encryption algorithm is a common algorithm for Android development. This is a detailed analysis of my self CSDN blog: General encryption is usually block encryption, if you want to encrypt data over the size of the block, you need to involve the filling and chain encryption mode, the text mentioned in the CBC and ECB, and so is the chain encryption mode. This document compares the image of the AES encryption algorithm introduced in some of the patterns reproduced. Attention, but also the lack of a CTR model. At the same time at the end of the article, posted by several of the use of ECB and CBC model standard algorithm on stream. Symmetry...
