Digital certificate Application Strategy--How to obtain digital certificate

Digital certificates can be applied to the relevant CA organizations on the Internet or to be generated by using tools such as MakeCert. You can apply for individual and unit digital certificates, secure e-mail certificates, code signing certificates, and server certificates, respectively, for different occasions. Online application of digital certificates you can apply for digital certificates to some CA centers online, and there are many CA centers dedicated to providing digital certificates online, such as China Digital Authentication Network (www.ca365.com ">http://www.ca365.com") ...

Digital certificate application--Management of digital certificate

Deleting a digital certificate incorrectly installed if you accidentally add a digital certificate to the untrusted zone, you can delete this: click "start → run", enter "Certmgr.msc", select "Untrusted certificate → certificate" in the open window, locate the certificate and right-click, select "Delete". Second, the digital certificate failure time to deal with the root cause certificates are applications that verify other certificates, including security certificates. If the root cause certificate on the computer fails, or if the date/time setting is incorrect, the digital certificate will be invalidated. If is the root cause certificate loses ...

Use of digital signatures, electronic signatures, and digital certificates

Q: What is the difference between digital signatures, electronic signatures, and digital certificates? A: Digital signatures are numbers that are calculated using an algorithm for the contents of a file. When this file is sent electronically, the number is appended to the back. When the receiving program receives a digitally signed file, it computes a number using the same algorithm, if the number does not match the digital signature, indicating that the file may have been modified during transmission (possibly by a man-in-the-middle attack). It does not show where content is modified, only whether the content is the same or different from the original send. Electronic signatures are basically the hands used in legal documents ...

Authentication and encryption

Certification (authentication) means that the user must provide proof of who he is, an employee, an agent of an organization, a software process (such as a stock trading system or a software process for a Web ordering system). The standard method of authentication is to figure out who he is, what characteristics he has, and what he knows to identify his things. For example, the system stores his fingerprints, and when he accesses the network, he must provide his fingerprints on an electronic fingerprint connected to the network (which prevents him from using fake fingerprints or other electronic information spoofing systems) and allows him to access the system only if the fingerprint matches. More ...

How does Digital Rights Management (DRM) ensure cloud security?

Another survey shows that security is a big problem for those who want to adopt cloud computing.   Ipswitch, a network equipment maker, asked 1000 customers whether they planned to invest in cloud technology in 2011. The good news is that more than two-thirds of customers are said to have given a positive answer.   The bad news is that most of what is needed is a private cloud environment (29%), or a mixed environment (21%) of a public cloud and a private cloud. No one agrees entirely with the elements of a private cloud, but it is generally agreed that a private cloud is a way to provide services like the cloud.

Gnupg-gnu PGP Usage Guide

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 ...

Network security deployment and implementation based on private cloud security platform

1, the background of cloud technology and the current situation in our country, anti-virus technology originated from the 1990s, based on a variety of signature detection methods of malicious code and based on file data, program behavior heuristic detection. With the development of cloud computing technology, manufacturers have put forward their own cloud security technology concepts and corresponding products.   However, most of these products do not deviate from the feature detection method, but the feature extraction and matching calculation methods have changed. The first is the migration of virus signatures from the client to the Cloud collection. In order to solve the file data constantly expanding, evil ...

PGP Dictionary

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 ...

The principle of PGP encryption

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...

Introduction to PGP

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.
