Encryption and decryption with OpenSSL

Encryption and decryption with OpenSSL

This tutorial shows how to use OpenSSL in Linux systems (Kali in the video) for symmetric and asymmetric encryption and decryption.

OpenSSL is a free and open-source toolkit that provides a robust, commercial-grade, full-featured toolkit for general-purpose cryptography and secure communication. Internet servers, including most HTTPS websites, widely use it.

OpenSSL contains an open-source implementation of the SSL and TLS protocols. The core library, written in the C programming language, implements essential cryptographic functions and provides various utility functions. OpenSSL also includes several command-line tools that can perform multiple cryptographic tasks, such as generating keys, encrypting and decrypting data, and verifying digital signatures.

OpenSSL is available for most Unix-like operating systems (including Linux, macOS, and BSD), Microsoft Windows, and OpenVMS. It is also known as a Docker image.

Here are some of the features of OpenSSL:

  • SSL/TLS implementation: OpenSSL provides an open-source implementation of the SSL and TLS protocols. These protocols are used to secure web traffic and other network communications.
  • Cryptographic functions: OpenSSL includes several cryptographic processes, such as encryption, decryption, hashing, and digital signatures. These functions can be used to protect data from unauthorized access.
  • Command-line tools: OpenSSL includes several command-line tools that perform various cryptographic tasks. These tools can generate keys, encrypt and decrypt data, and verify digital signatures.
  • Cross-platform: OpenSSL is available for most Unix-like operating systems, Microsoft Windows, and OpenVMS. This makes it a versatile tool that can be used on various platforms.

OpenSSL is a powerful tool that can be used to protect data and secure network communications. It is a widely used tool that many organizations trust.

Here are some of the benefits of using OpenSSL:

  • It is free and open-source.
  • It is widely used and trusted.
  • It is cross-platform.
  • It is powerful and versatile.
