**课程名称：** OpenSSL 密码学入门指南 - 第二部分 **课程概述：** 本课程将深入探讨对称加密和哈希函数，以寓教于乐的方式，让学习曲线变得轻松有趣。我们将深入了解密钥的生成过程，包括位流的置换、位的交换、移位、替换以及最终的按位异或（XOR）运算。 您将学习现代加密操作的基础知识，包括块密码的工作模式，以及算法如何组合使用块密码进行数据的传输。此外，我们还将学习哈希函数，了解如何通过哈希函数确保信息的完整性，以及如何利用加盐哈希（salted hash）、消息认证码（MACs）和 HMAC（基于哈希的消息认证码）来保证文件的完整性和真实性。 **学员评价（关于“OpenSSL 密码学入门指南 - 第一部分”）：** "很棒的老师，充满活力，善于沟通。" - Atela Dondth "Ofer 知识渊博，经验丰富。我真的很喜欢向他学习。" - Lisa Mind "超棒的课程！讲师对每个概念都讲解得很深入！" - Hana rebic "我非常喜欢这门课程。它教会了我关于密码学我所需要知道的一切。" - Tereza Alex "感谢 Ofer 带来如此精彩且易于理解的课程。" - Fred Barbosa "由于工作原因，我多年未接触密码学。我开始重新探索和复习一些知识，以更新我的经验和理解。这门课程以其分步讲解的视频，提供了一个绝佳的复习机会，讲解细致入微。无论是初学者还是想要整体复习的人，都非常合适。" **课程特色：** 这是一门**实践操作性强**的课程。讲师将教授理论知识和实际应用。立即加入，一起体验学习密码学的乐趣！
This Course Focus is on Symmetric Encryption and hash functions ,we will understand the inner parts, while still making the learning curve fun and simple We will look at secret key generation, how do we generate keys , it is much more complex than you thought it involves permutations of the bit stream , swapping bits , shifting, substitution them and finally doing the XOR bitwise operationYou will learn the basic of modern encryption operationsWe will dive into block ciphers mode of operation , how algorithms join the block ciphers together and send them along , a key concept of every symmetric encryptionAnd then we will learn of hash functionshash functions are calculated to keep our messages intact.how do we keep the integrity and authenticity of our files using salted hash and MAC's- Message Authentication Codes and hmacs , a cryptographic hash functionsWhat students wrote about "Cryptography For Beginners - Part 1Nick 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 AlexThanks for a great and easy to understand course ofer.Fred BarbosaI'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 is Hands On. I will teach you the theory and the practical usage. So come along , Cryptography is Fun
