High-speed offloading of IP networks, optical networks, and Rail TransitThree o'clock AM, sleep in the middle of the night, suddenly heard the left and right ears buzz, the tatami pad under the sound of the sand, thought in a dream, but woke up, found that did not see anything, still in the night, so I confirmed that this was not a dream. So when the light was turned on, I found a cockroach lying on the mat, but the two mosquitoes were unknown. When I
Wi-Fi technology, which has long been regarded as the "Ugly Duckling" in wireless technology, is rapidly developing into a necessary strategic tool for mobile operators. However, regarding the role of Wi-Fi in the operator's business, whether Wi-Fi can exist as a separate business model still needs to be combined with existing mobile services, but there is controversy between operators.
The simple story of using Wi-Fi as a low-priority mobile data traffic bearer method is being rewritten because

Further compress the pictureEven if you've adjusted the picture to the correct format and size, you can still compress the picture further using some tools for analyzing and optimizing the image. These tools include OptiPNG, PNGOut, Jpegtran, and Jpegoptim. Most tools can be installed independently or integrated into the process you build. In addition, there are some online tools, such as Smush, which can work on the cloud. 10.

SSL is a security protocol that provides privacy and integrity between communication applications that use TCP/IP. The Hypertext Transfer Protocol (HTTP) of the Internet uses SSL for secure communication.The data that is transferred between the client and the server is encrypted by using a symmetric algorithm such as DES or RC4. The public key algorithm (usually RSA) is used to obtain encryption key exchang
encrypted HTTPS protocol, if the HTTPS communication packets are intercepted during transmission, we can decipher the information in these packets, there are some user name, password, cell phone number and other sensitive information, and if the use of HTTPS communication, even if the packet is intercepted, And we can't decipher what's inside.

In the following two years, our domestic search engine also began to be based on whether the site to join the SSL certificate a discussion, but from the user experience
Chiang has shared many of the free SSL security certificate applications and installations in previous posts, although most of the installations are based on VPS and server deployments. Due to the company's project needs in the recent period of time will be unstable overseas VPS, server sites are required to relocate to a better speed of the Asian node virtual host, and some sites have used SSL security cer
Security Socket Layer (SSL) has been under attack since Netscape was developed in 1994. Security and Integrity of X.509 Public Key Infrastructure have also encountered many problems recently. Despite many warnings about SSL security, if correctly deployed and configured, SSL can still be used to protect data transmission between insecure networks. In this article
Prepare a digital certificate for developmentGeneral Learning and development debugging occasions, will not casually use the formal SSL server certificate private key. Because server authentication is required for SSL, the SSL server must have a server certificate that is able to access the private key of the certificate. For
Start the SSL function of the Serv-u ftp Server
Serv-u ftp Server is a widely used FTP Server software. It provides SSL functions but is not enabled by default. FTP transfers data in plaintext mode. To ensure data security, it is necessary to enable its SSL function. The procedure is as follows.
Step 1: Create a certificate for your Serv-u ftp Server. To use the
First, SSL Overview The SSL protocol uses digital certificate and digital signature for two-terminal entity authentication, uses asymmetric encryption algorithm for key negotiation, encrypts data with symmetric encryption algorithm and transmits it to ensure the confidentiality of data, and verifies whether the data is tampered and forged in the transmission process by calculating the Digital digest. Thus,
The early SSLv2 was designed according to the classic PKI (public key Infrastructure), which by default assumed that a server (or an IP) would only provide a service, so at the time of the SSL handshake, the server side could be sure which certificate the client was requesting.However, it is not expected that the virtual host has developed vigorously, which resulted in an IP will correspond to multiple domain names. There are some solutions, such as a
SSL principle HTTP and HTTPS differences
HTTP default port is 80,https default port is 443;HTTP transmits data to plaintext, HTTPS transmits data is encrypted;
HTTP is the HTTP protocol that runs on top of TCP. All transmitted content is plaintext, the client and the server can not verify the identity of the other side;HTTPS is HTTP running over SSL/TLS, and
