Although the development of mathematics, linguistics, and computer science has been quite powerful, there are still some strange password problems that have not yet been cracked. This article selects five unsolved password challenges. No matter

Password Management-hacker attack password In reality, when hackers attack an Intranet target, 90% will take deciphering the password of a common user as the first step. First, use the "finger remote host name" to find the user account on the host,

Data Encryption Standard There are two traditional encryption methods: replacement and replacement. The above example uses the replacement method: UseKeyConverts each character in plain text to one character in the ciphertext. Replacement only sorts

Password crackingThe specific steps are as follows: Search for "cracking the XP Password" on the Internet will see a lot of information, most of which are said to be able to crack the Windows XP operating system password is not universal, but can

RSAIn the algorithm description, the article uses the MyTestCert certificate generated by the makecert tool to holdEncryptionDecryption. This certificate has a 1024-bit RSA key pair. For details, see the following. Figure 12. RSA encryption and

Researchers from three universities and Microsoft have discovered this weakness. They have carried out a lot of cryptography analysis, however, the results of this study still do not constitute any actual security threats-which is more reassuring.

Password 1. Set a unique password for all your important accounts Set an independent password for all accounts, especially for important accounts such as email and online banking. You may have dozens of accounts online, and you cannot ensure that

A research group led by Professor Luo haiguang from the University of Toronto, Canada, found that a new quantum encryption method may defeat the "most sophisticated" hackers. This discovery was published in the latest issue of physical comment

Sometimes we often feel a big headache for forgetting important passwords, and the arrival of this new technology makes us no longer have to worry about it. This is a new security technology: Neurosecurity, which combines cryptography and

The hardware-based point-to-point encryption technology was approved by the Payment Card Industry Security Standards Committee Payment Card Industry Security Standards counsor (pci ssc), which has released updated requirements and test steps, to

When it comes to cloud security when it comes to being physically controlled and/or owned by others, is it possible to ensure the security of the virtual machine's key? In the most favorable circumstances, key management is still a heavy challenge.

After the shell is executed, it will jump to the Entry Point of the original program, that is, Entry Point, also known as OEP! When the encryption strength is not a very large shell, there will be a large cross-segment at the end of the shell and

Since we discussed "security and privacy of Android Applications" at last year's Google I/O conference, many people have some questions about how to use cryptography on Android. Most of the questions are about which API to use for a specific purpose.

HTML5 is the next generation of HTML, which gives the web page better meaning and structure. With the support of RDFa, micro-data, and micro-mode, more rich tags will be used to build a data-driven Web that is more valuable to programs and users.

Currently, hacker attacks have become a serious network problem. Many hackers can even break through SSL encryption and various firewalls to attack websites and steal information. Hackers can use their browsers and several techniques to obtain
