Researchers revealed that Adobe had confirmed that millions of passwords had been stolen in the October data breach, which were initially not saved as the best example in the industry. The password encryption method is easily cracked. In a statement issued by CSO, Adobe confirmed some details disclosed by Ars Technica last Friday. Adobe said that the password stolen in January was not encrypted by hash, but by common encryption, this means that Adobe

server, but its password is valid on the current day and will automatically expire on the next day. In this case, you only need to change the password when the customer or supplier needs to use the FTP server. Instead, you do not need to create a user each time you use it. After you use it, delete it. At the same time, it can also avoid security risks to the server because the temporary account is not canceled in time, because the password will automatically fail. Most FTP servers, such as the

We are always dealing with passwords when using computers. If the password you set is guessed or decrypted by others, important information and personal privacy will be leaked. Therefore, setting a secure password is a major event related to everyone. Next we will introduce the ten military rules that must be followed in the password setting process. I. Try to be as long as possible Generally, the password must be at least six characters in length. It

As the most popular server operating system on the Internet, UNIX security has attracted much attention. The security of UNIXD is mainly realized by password, therefore, the UNIX password encryption algorithm has improved several times, now commonly used des algorithm for password file 25 encryption, and the result of each DES encryption, to use 2 of the 56 times to find and match to do a traversal, to crack such a password, The amount of work is huge, so theoretically this password is quite saf

The lower-version Windows system uses character passwords, which, however complex, are theoretically possible to be violently cracked. and WIN8 system in order to prevent viruses, trojan program intrusion, using a very special picture password login function, the login method does not contain regular character content, virus, trojan program in the crack will not be able to do, which obviously will greatly improve the system security capabilities.

has been accessed recently, the chances of future access are higher."Implementation diagramThe most common implementation is to use a linked list to save the cached data, the detailed algorithm is implemented as follows:1. Inserting new data into the list head;2. Whenever the cache hits (that is, the cached data is accessed), the data is moved to the list header;3. When the list is full, discard the data at the end of the list.AnalysisHit rateWhen there is hot data, LRU efficiency is very good,

The Internet browser will have a history, log on to a website will remember the password, these historical records and passwords are actually left in the computer cookie, if you change a computer, there will be no previous records. This is different from the session, the record of the session is left on the server side, changed the computer, log in or can see the previous record.
