serial keys

A little bit confused about the public key and the private key, search for some information, do some sorting it, first look at this: Encryption--Public keyDecryption--Private keySignature--Private keyAuthentication--Public key Look at this. The private key may be used for signing, in fact, it is equivalent to the private key encryption, and public key authentication is to use the public key decryption, but not for confidential information. Because the public key is public. One more: 1) The publi

In industrial control, Industrial Computer (generally based on Windows) often needs to communicate with smart meters through serial ports. Serial Communication is convenient and widely used.Generally, the Industrial Computer communicates with each smart meter through RS485 bus. The RS485 communication mode is half-duplex and can only be round-robin by the industrial control PC as the master node on each Int

PHP groups two-dimensional arrays based on keys and two-dimensional arrays of keys. We often get a two-dimensional array, and we will find that the result is somewhat different from what we want. We may need to group the Array Based on a field in the two-dimensional array. First, let's look at the following array, Array ([0] => Array ([id] => 1 [wo_id] => 2 [evaluate_id] => 1 [type] => group 1 [ctime] => 20

fields. For example, the student table above, with an underscore number, is a field that uniquely identifies a student, and the Number field is the primary key of the table. Since the name of the student is unavoidable, the name is generally not used as the primary key to uniquely identify a student.Let's take another example to illustrate multiple fields as primary keys. For example, students choose the timetable (school number, course number, score
