Six encryption tools ensure Data Transmission Security

Encryption converts data from its original form to a form that can only be read by the decrypted. In essence, encryption aims to prevent unauthorized reading of data. Encryption technology can be elaborated from different perspectives. Today we only introduce the six most famous encryption tools.

1. GnuPG/PGP: These two tools can ensure advanced encryption of files and communications. PGP is a well-known encryption program developed by Phil Zimmerman. It can help us encrypt data and prevent eavesdropping and other risks. GnuPG is an open-source implementation of the PGP standard with good reputation. It not only encrypts, but also supports digital signatures for your data and communications. GnuPG, also known as GPG, is a command line tool that can be integrated with other applications. It has a large number of front-end applications and libraries. GnuPG is always free, and some PGP applications need to spend money.

2. OpenSSL: it is called the primary SSL/TLS encryption library. The OpenSSL Project is a robust and commercial open-source tool with many features. It supports SSL (SSL v2/v3), Transport Layer Security Protocol (TLS v1), and Common encryption libraries. This project is managed by volunteers worldwide who use Internet communications and are responsible for the compilation of relevant documents.

3. TOR: for companies that use Internet communications, Tor is a good tool that can improve the security of their communication. Tor can help users to anonymize web browsing and publishing, instant messaging, ssh, and other TCP-enabled applications. Tor also provides a platform where developers can build new applications with built-in anonymity, security, and privacy. However, Vidalia is recommended for free cross-platform GUI users.

4. Stunnel: this is a common SSL encryption program. Stunnel is designed to act as an SSL encryption program between a remote client and a local or remote server. It can be used to send and receive background programs (such as pop2, POP3, and IMAP servers) to General inetd without changing the program code. It can use the OpenSSL and ssleay libraries to successfully complete an SSL connection.

5. openvpn: openvpn is an open-source ssl vpn package. It provides a large number of configurations through load balancing, failover, and fine-grained access control, including remote access, site-to-site VPN, Wi-Fi security, and enterprise-level remote access solutions. Openvpn uses the industrial standard SSL/TLS Protocol to implement the security network expansion of the OSI Layer 2 or Layer 3, and supports flexible client Verification Based on certificates and smart cards, by using firewall rules adapted to VPN virtual interfaces, users or groups can use specific access control policies, which use OpenSSL as their primary encryption library.

6. truecrypt: this is an open-source disk encryption software in Windows and Linux. Truecrypt is an outstanding disk encryption system. Users can use it to encrypt the entire file system. without user intervention, it can achieve dynamic encryption and decryption. It can create a virtual encrypted disk inside a file and load it as a real disk, it can encrypt the entire hard disk partition or a storage device (such as a USB flash drive ).
