Linux Pgp Encrypt

GPG, the GNU Privacy Guard, is a non-commercial version of cryptographic tool PGP (pretty), which is used to encrypt and authenticate emails, files, and other data to ensure the reliability and authenticity of communication data. This article will introduce the GPG technology and related tools, designed to help online surfers "sincere" communication. First, PGP overview before introducing GPG, let's take a look at the basic principles and application rules of PGP. Like many encryption methods, PGP uses double keys to ...

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 ...

Earlier this month, a security company called Codenomicon found a serious loophole in the world's largest open-source cryptographic service, OpenSSL, which hackers exploited to steal the keys that Web sites use to encrypt online transactions and web connections, could have as many as hundreds of thousands of affected servers, caused serious panic in the circle. Fortunately, Codenomicon also released patches while releasing the vulnerability message. But better to prevent than to mend. Recently, including Google, Microsoft, Facebook ...

End-to-end encryption policies must take into account everything from input to output and storage. Encryption technology is divided into five categories: file-level or folder-level encryption, volume or partition encryption, media-level encryption, field-level encryption and communication content encryption. They can be defined further by the encryption key storage mechanism. Let's take a look at the grim forecast: According to the US Privacy information exchange, One-third of the U.S. people will encounter the loss or leakage of personally identifiable information from companies that store data electronically this year. Whether that number is not exactly right, anyway the public knows the data leaks ...

The NSA's "massive surveillance" data center in the Utah State Desert can screen and analyze most of the world's network traffic, from geographical locations, audio and video files, e-mail, instant messaging, social networks and other digital documents. Of course, it's not just the NSA that can track our digital footprint, but in this time of personal privacy, all kinds of government and business companies can master our words and every move. 　　As a common netizen, is there a reliable way to protect themselves? Earlier, the Washington Post had given five individuals to avoid NSA surveillance ...

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 ...

People often ask me if they really should believe in Oss. In other words, the worry is: is the OSS the angel that brings us a good life, or is it a demon that destroys our lives? As a matter of fact, this problem has been raised since the beginning of Linux and various BSD (Berkeley Software distribution) operating systems. In reality, any organization or enterprise is very cautious in planning to use a free software that is not from a reputable merchant. As a routine, generally ...

No matter what the purpose is to be monitored by others MSN information is not a good thing after all. Here's a summary of how to prevent this from happening under Windows and Linux. 1. Install Gaim for Linux or Windows. 2. Install gaim-encryption3.gaim-encryption So there is no way for others to monitor. Everything that is being monitored is encrypted information. http:// gaim-encryption.sou...http://...
