**课程名称：** Ethical Hacking: Crypto 101 **课程概述：** 本课程适合道德黑客学习基础密码学知识。课程将涵盖哈希（Hashing）的概念及其在网络安全中的应用，包括如何破解 Windows 和 Linux 的密码哈希，以及更广泛的密码学原理。 **核心内容：** * **哈希（Hashing）：** 学习哈希是将任意长度的数据转换为固定长度的字母数字字符串的过程。哈希值也被称为消息摘要。一个好的哈希函数应具备易于计算、抗碰撞（难以找到两个不同输入产生相同输出）、抗篡改（修改消息会导致哈希值改变）和单向性（难以从哈希值反推出原始输入）等特性。 * **哈希在安全中的应用：** 探讨哈希如何安全地存储敏感数据（如密码），即使哈希值被泄露，由于其不可逆性，也需要通过暴力破解才能恢复原始密码，对于当前计算能力而言，这通常是极耗时甚至不可能的。 * **密码哈希破解：** 学习使用工具破解 Windows 和 Linux 系统的密码哈希，从而获取用户密码。 * **数据完整性验证：** 理解哈希在验证数据完整性方面的作用。 * **基础密码学：** 了解基本的密码学概念。 **学习成果：** 完成本课程后，您将能够： * 熟练掌握哈希函数的工作原理。 * 使用哈希破解工具获取 Windows 和 Linux 系统的用户密码。 * 理解并应用哈希技术进行数据完整性验证。 * 掌握基础的密码学知识。
In this course you will learn about basic crypto for ethical hackers. You will learn about hashing, how to crack windows password hashes, how to crack linux hashes and about cryptography. Hashing is a process of converting a given input into a fixed-size alphanumeric string. The output of a hash function is often referred to as a message digest or simply, a hash. A good hash function satisfies the following properties: it is easy to compute the hash value for any given message, it is infeasible to generate two different messages that result in the same hash value, it is infeasible to modify a message without changing its hash value, and it is infeasible to determine the original message from its hash value.When used properly, hashing can be an effective way to store sensitive data such as passwords while keeping them safe from prying eyes. This is because even if someone were to obtain the hash value of a password, they would still need to brute force guess the actual password which would be incredibly time consuming (if not impossible) with today's computing power.After completing this course, you will be able to crack the passwords hashes from a Windows and Linux computer and find all users passwords using hash cracking tools. You will also be able to verify data integrity and understand basic crypto.
