Description:

This course provides an introduction to the fascinating world of cryptography, the art of secure communication. You will move beyond theory to master the practical tools used to secure data, ensuring confidentiality, integrity, and authenticity through industry-standard protocols like AES, RSA, and OpenSSL.

Key Highlights:

• Dual Pillars of Encryption: Mastering Symmetric (AES) and Asymmetric (RSA) systems.
• Data Integrity: Using SHA-256 hashing to detect unauthorized tampering.
• Digital Trust: Implementing digital signatures for authentication and non-repudiation.
• Command-Line Mastery: Practical hands-on experience using the OpenSSL toolkit.

What you will learn:

• Master the Two Pillars Solve the "Key Distribution Problem" by comparing Symmetric (AES) and Asymmetric (RSA) encryption in "The Key Architect" scenario challenge.
• Enforce Data Integrity Master hashing and the "Avalanche Effect." Identify tampered data by comparing SHA-256 hash digests in "The Checksum Challenge."
• Verify Trust & Identity Ensure non-repudiation using digital signatures. Practice the step-by-step workflow of signing with Private Keys and verifying with Public Keys.
• Execute OpenSSL Labs Get hands-on in a simulated terminal using openssl to encrypt files with AES-256 and generate RSA key pairs for digital document signing.
