Keys can be symmetric (a single key used by all entities involved) or asymmetric (two keys, known as a public and private key pair) whereby separate entities retain their own private key to decrypt data secured with their public key which is available to all entities. What are file encryption techniques?Įncryption relies on encoding algorithms (also known as ciphers) which scramble data via digital keys (measured in bit sizes) to secure the information. The type of encryption I’m discussing in the scope of this article relates to file encryption to secure data accessed either locally or remotely, either on a per-file or per-folder basis or applied to entire disk volumes. VPN connections and browsers that access secure websites prefaced with “ in the URL use encryption with which the end user or IT department does not have to take any specific action (other than those responsible for administering the web servers or network endpoints and the manner in which they operate). There are different types of encryptions involving data and network traffic.
