The key to using the global unique ID (each MCU has a unique ID) is to prevent the program from being read easily, and even hex ROM does not have to be encrypted at all, and it does not matter how easy it is to decipher the hex code. In fact, it only takes two steps: 1. Think of a very good algorithm, using the MCU GUID to generate another ID (variable length), and then des

First, Introduction ENC-symmetric cryptographic routines, which use symmetric keys to decrypt data, are characterized by fast speed and the ability to process large amounts of data. Algorithm has a stream algorithm and packet encryption algorithm, the stream algorithm is byte-wise, because it is easy to decipher, it is now rarely used; the packet encryption algorithm divides the data into fixed-size groups and then encrypts them in groups, such as DES

Many times you won ' t need to decipher a regex character by character, but sometimes if you do the it helps you learn. Just Remember, Don's be afraid of regular expressions, they might isn't seem it, but they make your life a IoT easier. Just try and pull out a
keep the life of your users, while keeping your database fast with numbers (MySQL really likes them plain numbers ;).
To do the conversion I 've written a PHP function that can translate big numbers to short strings and vice versa. I call it: alphaID.
The resulting string is not hard to decipher, but it can be a very nice feature to make URLs or directorie structures more compact and significant.
So basically:
When someone requests rLHWfKd

First Use $_get["s"] to get the parameters of the URL, and then use Passport_decrypt to decrypt it, and then use Unserialize to restore its data to the original data, to this process, your Web page may be free to jump through the header.This method also involves security issues, if your URL address in the process of transmission by someo

Instead, the goal is to demonstrate how can decipher Go sources on your own.Before we can begin, we certainly need our own copy of Go source files. There is nothing special in getting them. Just Execute:

3D card is not low)Fifth Step: Security Obviously, you can't trust users. It is not always possible to assume that the user will not be able to decipher your ingenious encryption algorithm (if you use it) or the protocol, and that any information sent by the user will be verified. Most likely, on your server, you have a fixed buffer. For example, there is usually a small (possibly 4k) buffer used to receive data (from Soket). Malicious users send
