OrderThe second one-way encryption algorithm--sha is briefly introduced in the previous article, and the Java code of SHA-1 is also given. Children's shoes with this need can be consulted. Today this article will introduce the third one-way encryption algorithm--hmac, in fact, this encryption algorithm is not so common, at least, before I write a series of blogs, I have not heard of it. Of course, this is n

If your API Service Security Authentication Protocol requires the hmac_sha1 method to encode information, and your service is implemented by PHP, the client is implemented by JAVA, in order to correctly compare the signature, a matching encoding method needs to be established between the two. the PHP side is as follows: define (ID, 123456); define (KEY, k123456); $ strToSign If your API Service Security Authentication Protocol requires the hmac_sha1 m

On the mobile phone, the offline map package is usually placed on the SD card and then read through the file. For the sake of simplicity, put offline in the Resource Directory of the example and compile it with the application. In actual applications, store these map packages separately. The Guide bee map development kit supports reading multiple map packages at the same time. This is done through the MapTiledZone class and MapTileStreamReader class.
