How To Make Your Own Encryption Program

The necessity of database encryption large database management system platform is typically Windows NT and Unix, these operating system security level is usually C1, C2 level. They have user registration, user identification, Arbitrary access control (DAC), audit and other security functions. Although the DBMS on the basis of the OS added a number of security measures, such as access control based on permissions, but the OS and DBMS on the database file itself is still lack of effective protection measures, experienced online hackers will "bypass", directly using the OS tools to steal or tamper with the database files ...

There is no doubt that people who understand the technology of data encryption should be able to protect the security of the source of technology. 　　Because of the direct use of data, so that data even if the security crisis lost, was stolen, encryption protection can still guarantee the real content of the data security. But the flexibility of data encryption is the place where people have been criticized. From the initial information encryption is not convenient to transparent encryption, from the beginning of a single encryption to the current Multimode encryption, encryption technology is also constantly improving to cope with the increasingly rich demand for encryption. and the development of data encryption technology is not only this, in order to deal with the more ...

Every day, the world due to software piracy caused by the loss of not less than 50 million U.S. dollars, even in the so-called legal system of the most perfect in the United States, piracy rate of up to 21 (data from IDC). Software piracy has become a major test of the survival of the software industry, and encryption has become a helpless choice. If the anti-virus technology update is driven by the virus manufacturer, then, the software encryption industry is a game with the decryption, but also promote the market demand for the development of the industry. In the initial encryption process, most of the software used by the soft encryption method, the main ...

E-Mail has become the most convenient way of communication in the Internet age, because of the freedom of the Internet, so the security of the mail is becoming more and more prominent. Today, with the popularity of the Internet, e-mail is becoming more and more popular, open a book or magazine newspaper, have an e-mail address, even the ads are marked with e-mail address; this has become a fashion, the most convenient way to communicate in the Internet era, save money, fast. It is because of the freedom of the Internet, so the security of the message is increasingly prominent. e-mail Message delivery, general ...

In fact, encryption is not easy. Edward Snowden, former director of the National Security Agency, had previously wanted to communicate via encrypted e-mail with journalist Glenn Greenwald, who watched Snowden's 12-minute tutorial After the video, still not sure how to use the famous encryption program PGP. Nadim Kobeissi wants to clear this learning disability. At the HOPE Hacking Conference in New York later this month, he will announce a release titled min ...

To prevent pirated software from infringing the software market, more and more software providers use encryption to protect their software. Although there are many ways to encrypt optical discs at present, the main principle is that some of the feature information on a special disc master is not reproducible, and most of these features are not data on the disc, and are not copied when the disc is copied. In order to enable us to have a certain understanding of the technology of the encryption disc, the following is a brief introduction to some newer encryption techniques. 1, CSS encryption technology in English all called content scram ...

PGP is a mail encryption software based on RSA public key encryption system. You can use it to keep your emails secret to prevent unauthorized reading, and it can also digitally sign your emails so that the recipient can be sure you sent them. It allows you to safely communicate with people you've never met before, and you don't need any confidential channels to pass the keys. It uses: Prudent Key management, a RSA and traditional encryption of the hybrid algorithm for digital signature of the message digest algorithms, encryption, and so on, there is a good ergonomics design. It's powerful and fast. And...

First, generally speaking, encryption is the shell we often consider, an executable file, how to encrypt to be safe? The usual means is the Packers. The working principle of the Shell tool is to encrypt the code and data of the executable file as data storage. The generated target file entry code is the anti-trace code prepared by the Packers software. After a long code, the code of the original executable file and the Data section restore, and then jump to the original entrance, continue to run. The disadvantage of this is that no matter how strong your encryption, anti-tracking code more cattle, as long as a running, in ...

6th chapter of software Protection techniques common Protection skills 1, serial number mode (1) Serial number protection mechanism mathematical algorithm is the core of password encryption, but in general software encryption, it does not seem to be very concerned about, because most of the time the software encryption itself to achieve a programming skill. But in recent years with the popularity of serial number encryption programs, the proportion of mathematical algorithms in software encryption seems to be getting bigger. Let's take a look at the way the serial number encryption works on the network. When a user downloads a shareware--share software from the network, ...
