security encryption software

After we write a software, we do not want people to steal our software, at this time we can register to protect our work. At this point we may need to understand the encryption and decryption technology, here is my brief summary: The first step: The program gets the only indication of the running machine (for example: Network card number, CPU number, hard disk n

The role of data encryption in our lives has become increasingly important, especially given the large number of transactions and data transmissions that occur on the web. If you are interested in adopting security measures, you will also be interested in understanding the range of security features provided by PHP. In this article, we will describe these feature

are countless negative cases.Project risks are divided into the following types:1. Risk of cracking after Data EncryptionDocument encryption controls the application software. The generated document is written into the key when it is saved. However, when the ciphertext is opened on a computer with the encrypted product client, the encryption

Comments: For a long time, MD5 encryption and verification are very secure. Many forums and software Save the password of the user name after MD5 encryption. Compared with the previous plaintext storage, the stored information after MD5 encryption is more secure. After all, the information after MD5

Networks initially adopted the WEP (Wired Equivalent private) security mechanism, but later found that WEP was insecure. 802.11 organizations began to develop new security standards, that is, the later 802.11i protocol. However, it takes a long time for the establishment of standards to the final release, and considering that consumers will not give up their original wireless devices for the sake of networ
