As we all know, Windows Vista has made great improvements in security to ensure the confidentiality of user data. The system-level security protection BitLocker provided in Windows Vista Enterprise and Ultimate can provide the complete drive encryption function, this effectively prevents Windows Vista users from being threatened by data theft or leakage due to PC hardware loss, theft, or improper elimination. Even if an illegal user starts another system and browses files stored in a protected d

SummaryPreviously written to see other people write scripts with SHC encryption, I also have to understand the next.SHC represents shell script compiler, the shell scripting compiler. A script that has been compiled by SHC is not readable to ordinary users, so if you want to protect your code (for example, with a key), you can consider SHC; however, some people can use the reverse compiler to crack the SHC encrypted script.Let's start by introducing:I. Using SHC to

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 certificate. But fortunately, most of the virtual hosts are currently using the Cpanel panel

Most of us use cloud storage services like Dropbox, gdrive or copy to use synced files from any of our devices, anytime, anywhere. But no one will be relieved to put their sensitive data on the cloud storage platform. Recent hacking events have shown how insecure our data is. In 2014, many celebrity photos were leaked from cloud storage platforms and posted on social networking sites. So, why not encrypt the data before uploading it to the cloud stora

Use ASP encryption algorithm to encrypt your data IntroductionFirst, briefly introduce the background of encryption. Because the United States prohibits the number of outgoing encrypted digits of several cryptographic algorithms (such as the 40-bit SSL encryption limit), this article will introduce a simple character encryption algorithm that ASP can use, instead of those restricted encryption algorithms. As a matter of fact, the encryption

fact, CSPs may encrypt data with special hardware devices (such as smart cards. The CryptoAPI allows simple function calls to encrypt data, exchange public keys, hash a message to create a digest, and generate a digital signature. It also provides advanced management operations, such as using a CSP from a group of possible CSPs. In addition, CryptoAPI provides the foundation for many advanced security serv
