This requires the

Data communication and network notes-CSMA/CD and CSMA/ca csma/CD Working Principles CSMA/CD (Carrier Sense Multiple Access/Collision Detect) that is, the multi-channel access/conflict detection mechanism of the carrier listener, which works in the shared Ethernet and is applied to the Layer 2 data link layer of OSI. Its working principle is: Listen to whether the channel is idle before sending data. If it is idle, send data immediately. If the channel

Centos7+nginx issuing and configuring SSL services through Windows CARecently in the knowledge of Linux, as a necessary knowledge of operations engineer, a Web service especially run on the Internet is very easy to attack, so in order to ensure the minimum security needs to configure the Web service SSL, this can improve the security, so we introduce today, CENTOS7 +nginx The SSL service is issued and configured through the Windows CA, of course, if i

In this case, the length of the backend field/decimal point can be automatically adapted to the front-end when there is a change.Then change the CA, and the input interface is also adapted, which is much more convenient.

In HTTPS learning note two, the concept of digital certificates has been clarified, composed and how the client validates the server-side certificate during the HTTPS connection process. This chapter describes how to use the OpenSSL library to create a key file, and to generate a root CA and issue a child certificate.

To solve this problem, we have a third-party CA4.3 One-way encryption: Extract data Fingerprint (signature), can only encrypt, cannot decryptCharacteristics: fixed-length output, avalanche effect (small changes in initial results will result in a dramatic change in results)Function: Realize the integrity check of dataAlgorithm: Md5:message d

If the success of the OTA or USB, if the failure to ask if the need to upgrade the serial port, the reason is: if the check will determine whether the front panel can be forced into OTA or USB upgrade, can not, it means that loader or the app is damaged, this time you need to use the serial port to force the application or loader.2.

In a recent project, the establishment of the PKI system has not been completed before, so it was confused at the beginning. I slowly found out some results and shared them with you. I hope you can correct the incorrect information. At present, the PKI system has become the key point of information security in an enterprise and is the pillar of information security. My project is based on Microsoft technology. The CA Certificate Server is a self-built

symmetric key with the public key of the receiver, attaches it to the tail of the cipher, and sends it; Decryption process: 1. The receiving party decrypts the encrypted symmetric password with its own private key; 2. The receiving Party uses the password to decrypt the text; 3, the receiver uses the sender's public key to decrypt the sender's private key encryption signature; 4, the receiver uses the same one-way encryption algorithm to calculate the original data signature; 5, the receiver co

First, the HTTPS service must be built with an HTTPS certificate. This certificate can be viewed as an application-level certificate. The reason for this is that the HTTPS certificate is generated based on the CA certificate. For official websites, CA certificates require a qualified third-party certification authority to apply for access. For some of our self-built small projects, you can use your own serv
