![]() They are each an independent and necessary part of the system and are based upon solid mathematical foundations. The important part of this two-key system is that neither key can be calculated by having the other. GPG uses public key encryption wherein you create a key pair: one private or secret key you keep to yourself and one public key you share with your correspondents or the world. This conversion is achieved by applying the keys to the plaintext according to a set of mathematical instructions, referred to as the encryption algorithm.ĪLSO READ: DVWA SQL Injection Exploitation Explained (Step-by-Step) In cryptographic terms, the data or message to be encrypted is referred to as plaintext, and the resulting encrypted block of text as ciphertext. Processes exist for converting plaintext into ciphertext through the use of keys, which are essentially random numbers of a specified length used to lock and unlock data. One of the building blocks of security is encryption, which provides a means of scrambling data for secure transmission to other parties. This way you can be assured that you secret file is not targeted by any hacker to steal the data. Once the file is received by the client, they can further decrypt the file before viewing the content. You can encrypt a file using signed GPG key before you transfer or send the file to the recipient. ![]() In this article I will guide you with the steps to secure your critical data before transferring the file to your client. Security is a major part of the foundation of any system that is not totally cut off from other machines and users. ![]() In my last article I shared the steps to improve Disk IO Performance in Linux. ![]()
