PGP itself is a data security product, what security problems does it have? "No data security system is unbreakable," Philzimmermann, author of PGP, said in the PGP document. "PGP is no exception. We look at its security vulnerabilities in order to let users know what will degrade the security of PGP and how to avoid them. Here are the vulnerabilities: passwords or private key leaks, public key tampering, files that you delete are restored, viruses and Trojan horses, physical security is violated (physical security refers to the security of physical resources such as computers) 、...
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 ...
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 modern society, e-mail and file transfer on the network has become a part of life, the security of the message is increasingly prominent. It is well known that the data transmitted over the Internet is usually unencrypted, and if you do not protect your important information, the third party will easily gain your privacy. Another problem is information authentication, that is, how to convince the recipient that the message has not been tampered with by a third person, which requires digital signature technology. PGP is such a product. Pgp--pretty is a Privacy based RSA public key encryption ...
In the modern information society, when the email is popular, the security problem is also very prominent. In fact, the process of e-mail transmission is the process of repeated replication on the network, the network transmission path is uncertain, it is easy to be unknown identity of the theft, tampering, and even malicious destruction, to send and receive both sides trouble. Information encryption to ensure the security of the transmission of e-mail has become an urgent demand for the vast number of e-mail users. The appearance and application of PGP solves the problem of secure transmission of e-mail well. Combining the traditional symmetric encryption with the public key method, we have two ...
Cloud computing is a new internet based computer technology, it integrates the distributed computing, utility computing, parallel Computing, grid computing, networked storage, virtualization and other traditional computer and network technology, forming a set of new standards and models, "cloud computing" concept is rapidly applied to the production environment, all kinds of "cloud computing" The scope of service is growing and its influence is incalculable. In layman's terms, cloud computing is a way for you to give all data processing tasks to the network, and the Enterprise Data Center is responsible for processing the data tasks on the client's computer so that you can pass a data ...

As an important means of protecting information confidentiality, integrity and non-repudiation, encryption and digital signature are widely used in various information and communication situations. At present, there are many commercial encryption and digital signature products, such as commercial software PGP (pretty good Privacy). In addition, there are free encryption and digital signature software in the open source repository, the most recognized being GPG (GNU Privacy Guard). GPG is a completely free, source-code-compliant software product that is completely compatible with PGP. Today, GPG has ...
