Nick Camus

"Great teacher, alive, and communicative."

Atela Dondth

"Ofer is so knowledgeable and experienced. I really enjoyed learning from him."

Lisa Mind

"Awesome course! The instructor really goes indepth on every concept!"

Hana rebic

"I absolutely loved this course. It taught me everything I needed know about cryptography."

Tereza Alex

Thanks for a great and easy to understand course ofer.

Fred Barbosa

I've not done much in the way of cryptography for many years because of the jobs that I've held not requiring it. I've begun exploring and revisiting some things to freshen up my experience and understanding. This was a great way to revisit with good detailed explanations in the step by step clips that were offered. Great for beginners or just an overall refresher.

This course isHands On. I will teach you the theory and the practical usage.

You will understand how HTTPS works with public key cryptography and how to use Hash functions to keep your files integrity safe

WHY openSSL cryptography ?

Cryptography is everywhere, if you are an ethical hacker, Developer, an IT manager or anyone who hangs around with technology, than this is the stuff that you deal with everyday

In this course you will learn to generate symmetric keys , public keys, certificate request, hash functions and more

You will understand the theoretical concepts of encryption using public and private keys , and use the power of openSSL to apply them

This course is HANDS ON . no power points or fancy words .


  • how encryption works

  • when do we use encryption

  • cipher algorithm operations

  • what are symmetric keys

  • generate and apply symmetric keys on openSSL

  • hash functions

  • when do we use hash functions for integrity and when for confidentiality

  • hash different files on your computers

  • public key cryptography

  • the theory beyond public and private key

  • digital signatures

  • create your own certificate signing request
