File security is a fundamental concern for individuals and businesses alike. As data breaches become more frequent, encrypting sensitive information becomes critical. One of the tools available for Linux users is OpenSSL, a powerful toolkit for the Transport Layer Security (TLS) and Secure Sockets Layer (SSL) protocols. In this blog, we explore how to symmetrically encrypt and decrypt files using OpenSSL with the aes-256-cbc cipher and the pbkdf2 option. Q1: What is symmetric encryption?
A1: Symmetric encryption is a type of encryption where the same key is used for both encryption and decryption. It's effective for securing data as long as the key remains private and shared only among authorized users.
