PGP 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 met before, and you don't need any confidential channels to pass the keys. It uses: Prudent Key management, a RSA and traditional encryption of the hybrid algorithm for digital signature of the message digest algorithms, encryption, and so on, there is a good ergonomics design. It's powerful and fast. And...
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.
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 ...
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 ...
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 ...
1 Introduction e-mail plays an important role in people's work. According to statistics, the average Chinese per user receives 4.4 mails a week, sends 3.6 emails. But the primary protocol for e-mail, such as SMTP, is delivered in plaintext. This information may be obtained by a third party when it passes through an untrusted internet. In a modern society that attaches importance to information security, it clearly meets the requirements. How can this information be kept confidential without tampering or forgery? The PGP (Pretty-Privacy) described in this article is a kind of software, which is mainly used for electric ...
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 ...
