Knowledge 2. Experience 3. Feel 4. Patience of the 5. Luck。 If you just started to learn crack, maybe you met a lot of trouble, and a little want to retreat, in fact, you do not worry, as long as you seriously study ...

Now the garbage rogue software is really pervasive. Use IE to surf the internet, ie in the recruit has nothing to say. I do not use IE Internet, ie can also recruit, this is really amazing. One day opened the dust-laden for a long time ie, found that the address bar more "Chinese Internet" words, know the recruit. The last time I used it well, it was strange. And I also know that IE is vulnerable, never only to see the trustworthy site. And no matter how the recruit, since the middle, we will kill it. Turn on IE 6 Add-on management to disable all suspicious items. I faint, the slightest effect, the fellow is still alive ...

"Rogue Software" refers to the surface of a certain value but at the same time have some computer viruses and hacker program characteristics of software, performance is forced to invade the Internet users of the computer, forced pop-up ads, forcing users to accept certain operations, or users do not know the premise of the forced installation of IE Plug-ins, without uninstall program or can not completely uninstall, Even hijack the user's browser to go to some designated sites, etc. Experts pointed out that to deal with "rogue software" there are five strokes: first, do not log on to some bad web site, some sound painting full of temptation of the page, do not feel curious and try to click. Second, do not download some unfamiliar soft ...

I. Preface: With the vigorous development of the Internet network, the application of various networks continue to be new, in our daily life, whether it is a routine or office business, the network for you and I, is already an indispensable part of life! There are many times when we need to use the help of the Internet to disseminate messages or to information we want through the Internet. The network is so convenient and easy to use, but have you ever worried: if it is important and extremely confidential information, in the vast network of the sea, how to ensure the security and confidentiality of information? Yes, information security is a very important subject. Internet ...

It is the first algorithm that can be used both for data encryption and digital signature. It is easy to understand and operate, and very popular. The name of the algorithm is named after the inventor: Ron Rivest, Adi Shamir and Leonard Adleman. But the security of RSA has not been proved theoretically. It has undergone various attacks and has not yet been completely breached. One, RSA algorithm: First, find out three number, p,q,r, where P,q is two different prime numbers, R is with (P-1) (q-1) coprime number ... p,q ...

With the development of network and computer technology, the security of data storage and data exchange has become more and more important, and encryption technology has been used in data saving and data exchange very early. In order to ensure the correctness of the identities of both sides of the network data exchange, the visa system has matured. GnuPG is a set of tools for encrypting data and making certificates, and it works like PGP. But PGP uses a number of proprietary algorithms, which are among the notorious U.S. export restrictions. GnuPG is the GPL software, and does not use any patented encryption algorithm, so that ...

ASCII Armor ASCII encoding, encoding binary files with 7bits of display ASCII code, which can be passed in only 7bits-supported emails. The MIME BASE-64 encoding is used in PGP. ciphertext ciphertext; Encrypted later information, generally unrecognized. Cryptanalysis analysis of cryptography, from the point of view of cryptography to find a loophole and attack it, PGP in cryptography is still quite solid. Even Hack ...

ElGamal algorithm can be used both for data encryption and digital signature, and its security depends on the problem of computing discrete logarithm on finite field. Key pair generation method. First select a prime number p, two random numbers, G and X,g, x < P, and compute y = g^x (mod p), the public key is Y, G, and P. The private key is X. G and P can be shared by a group of users. ElGamal is used for digital signatures. The signed information is M, first selects a random number k, K and P-1 coprime, calculates a = g ...

This article mainly introduces some principles and background knowledge about PGP implementation. Other documents on the installation and use of PGP refer to other documentation provided with this article. PGP pretty-Privacy 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 seen before, and you don't need any confidential channels to pass the secret.

As we all know, the Internet is based on TCP/IP protocol, but the TCP/IP protocol in the original design and later application, did not take into account the security factors, also did not anticipate the application of the outbreak of growth. It was like opening a closed window in a confined room, fresh air coming in, but a lot of dust, flies and mosquitoes came along. The Internet world also, open, free information brings the convenience of communication, but the emergence of spam, internet viruses and hackers and other dark things, so that the network is experiencing unprecedented impact. Therefore, a variety of network security technology emerged. ...

PGP is a very popular international encryption software, its function is very powerful, can encrypt various files, generate 256-bit, 512-bit, 1024-bit key. PGP uses the public key encryption system, uses the encryption algorithm to generate two keys, respectively as the public key and the private key. The public key is used for encryption. The private key is used to decrypt and save itself. Here is a description of the use of PGP: 1 first generates your PGP key. In DOS command line input: The Pgp-kg2 program prompts you to step through the key generation: ① Select the key length. Recommended 1024-bit, safety ...

PGP (Pretty) is a program that allows your e-mail (e-mail) to have a confidential function. This allows you to encrypt your message (Encrypt), and no one else can read it except those you want to see. Once encrypted, the message looks like a bunch of meaningless garbled characters (Random Characters). PGP provides a very strong protection function, even the most advanced decoding analysis technology can not read (Decrypt) encryption ...

Describes the use of unmanaged Win32apis encryption to decrypt data before. NET is a very painful thing to do. For the purpose of this cryptographic decryption. NET is configured with a set of classes (and namespaces). Now you have a lot of classes that can protect your data using each of these different algorithms. There are 3 types of encryption methods defined within the. NET Crypttography namespaces. They are asymmetricalgorithm,symmetricalgorithm and HashAlgorithm. All the ...

PGP encryption software is the United States Receptacle Associate Inc. produced free software, it can be used to encrypt files, mail, in common WinZip, WORD, ARJ, Excel and other software encryption functions can be cracked, choose PGP on their own private documents, Encrypting a message is a good idea. In addition, you can also have PGP software with friends to pass each other encrypted files, security is very secure. PGP version 6.5 is a free version, can be downloaded on the www.pgp.com, size about ...

We know that PGP (pretty) is the most popular kind of encryption software at present, it is a mail encryption software based on RSA public key encryption system. We can use it to keep the message confidential to prevent unauthorized reading, and it can also digitally sign the user's message so that the recipient can be sure of the sender's identity. It allows users to communicate securely with people they have never seen before, without requiring any secrecy to pass the key, because it uses an asymmetric "public key" and "private key" encryption system. But PGP is not a completely asymmetric addition ...

SSL (Securesocketlayer) is a secure communication standard primarily used for the web, located between the transport layer and the application layer. Data is encrypted as it flows through it, again to TCP/IP, and the data from the TCP/IP into its first layer is decrypted, and it can verify the identity of both ends of the network connection, it provides a security mechanism to ensure that the HTTP transaction in the transmission is not monitored, forged and tampered with. SSL is now the de facto standard for securely transmitting data over the Internet, and this protocol is integrated into every common ...

The use of security programs does not guarantee that your communication is secure. Even if you install one of the safest locks on the front door, thieves can still crawl in through the open window. Also, even with PGP, your computer may still be vulnerable. There are many famous attacks on PGP, and the following sections describe these attacks. However, these are by no means a complete list. Future attacks are likely to compromise all public-key cryptography technologies. This checklist just gives you an idea of what you need to do to protect your communications. 1. The most direct attack on PGP by brute force attacks is the key used by brute force attacks. Because...
