Create/inspect key pair, encrypt/decrypt and sign/verify using OPENSSL
8This is a lab which shows how to create/inspect key pair, encrypt/decrypt and sign/verify using openssl
This lab is from Coursera's Google "IT Security: Defense against the digital dark arts" This lab DOES NOT REVEAL answers as it is simply copy and paste commands.
Introduction
In this lab, you'll learn how to generate RSA private and public key pairs using the OpenSSL utility.
OpenSSL is a commercial-grade utility toolkit for Transport Layer Security (TLS) and Secure Sockets Layer (SSL) protocols. It’s also a general-purpose cryptography library. OpenSSL is licensed under an Apache-style license, which means that you’re free to get it and use it for commercial and non-commercial purposes (subject to some simple license conditions).
You'll access OpenSSL through SSH onto the Linux VM instance associated with your temporary Google Cloud account. You'll need to sign in to that account and access the Linux instance before continuing.
What you’ll do
OpenSSL -You'll explore what generating key pairs looks like using OpenSSL by using SSH to access the Linux instance.
Encrypt and decrypt -You’ll use the key pair to encrypt and decrypt some small amount of data.
Verify -You'll use the key pair to sign and verify data to ensure its accuracy.
