This tutorial will give you a better understanding of lajp.Running environment requirements PHP and Java are both excellent programming languages on the exaggerated platform. There is no limit on lajp. Any environment that can run php and any environment that can run Java can run lajp. Lajp has two transmission mechanisms: M

security of each record, and the SHA algorithm can guarantee a very different result, even if there are only insignificant differences. The structure of the blockchain, when any block changes, will affect all subsequent chunks, so if you want to modify the contents of a block, you must modify the contents of all blocks, which is almost impossible, thus ensuring the security of the block data.Furthermore, the result length of SHA is fixed and not related to the content of the original text, so t

Essence | Digest-response object (2000.03.22) Response objects Response objects are useful and feature-rich. Here we are going to introduce to you the most basic function. Of course it's all a lot more functional than we're here to introduce, but we think the 20% of the The content is that you will be able to use it in 80% of the time. We think the main functions of the response object are as follows: # RESPONSE. WRITE # RESPONSE. Write can also be

input data changes, the hash will also change. Hash can be used for many operations, including identity authentication and digital signature. It is also called "Message Digest ". Algorithm used to generate hash values of some data fragments (such as messages or session items. By using a good hash algorithm, all the bits in the hash value of the result can be changed by making changes in the input data. Therefore, hash is useful for detecting changes

I have also written a PHP article digest generation method (function) before, but it is not very easy to use and garbled. now I release another function, which was removed from an open-source system, if you want to use the strip_tags () command to generate a digest, add strip_tags () to the function, add it by yourself. The following are functions: The code is as follows: Function cutstr ($ string, $ len
