Digital security is getting stronger, so criminals and law enforcement alike may be more willing to physically take your laptop or storage device to gain access to your data. It’s possible, however, to protect yourself against this invasion of privacy thanks to encryption.
This article will discuss disk encryption, its uses and types, and its advantages and disadvantages. We will also show you how to encrypt a Linux hard drive and the various Linux encryption methods at your disposal.
What Is Disk Encryption?
Encryption is the process of converting textual data into a secret code (a.k.a. ciphertext) for secure communication between multiple parties. Users can encrypt files or messages so that they are only accessible to other selected clients using shared protocols and encryption algorithms.
Types of Encryption
The challenge of encrypting data has been tackled by some of the world’s brightest minds for generations. Leading intelligence agencies, cybersecurity consultant firms, and computer scientists have dealt with this issue, developing various encryption types and standards. The most prominent ones include the following:
Public Key DES AES RSA Post-Quantum Homomorphic Elliptic-Curve Uses of Encryption
Developers and IT experts most commonly use cryptographic systems for the following applications:
Network monitoring tools CASB (Cloud access security brokers) Password managers NGFS (Next-gen firewalls) WAF (Web app firewalls) VPN (Virtual private networks) WEP (Wired Equivalent Privacy) and WPA (Wi-Fi Protected Access) wireless standards Data-at-Rest Encryption vs. Full-Disk Encryption in Linux
A data-at-rest encryption program encrypts and decrypts data
