## 实用密码破解课程（Coursera）课程总结 本课程深入探讨了密码破解的原理与实践，旨在帮助学习者理解密码的脆弱性，以及如何通过技术手段获取密码。课程指出，绝大多数用户为了方便记忆，倾向于设置包含个人信息（如生日、家人姓名、手机号）等弱密码，这为黑客攻击提供了可乘之机。 课程强调了创建强密码的重要性，并列举了强密码的几个关键特征：至少包含8个字符、字母、数字和特殊字符的组合，以及大小写字母的混合使用。 接着，课程详细阐述了密码破解的动机和技术。虽然课程名为“破解”，但其目的更多在于“探索”和“理解”，而非恶意攻击。课程解释道，在现代安全系统中，原始密码通常不会直接存储，而是存储其“哈希值”。哈希函数是单向的，使得从哈希值反推出原始密码极为困难。然而，正是这种机制使得密码破解成为可能，因为攻击者可以通过各种方法（如暴力破解、字典攻击等）来猜测并比对哈希值，从而找到与存储哈希值匹配的原始密码。 课程将教授以下几种主流的密码破解技术和工具： * **XHydra** * **Cracking SSH** (破解SSH) * **Ncrack** * **Using Word List** (使用字典攻击) * **Crunch** (用于生成字典) * **Advance Password Hacking** (进阶密码破解技术) 通过学习本课程，学员将能够掌握从密码哈希中提取原始密码的实用技能，从而更深入地理解网络安全攻防机制，并学会如何保护自己的账户免受潜在威胁。
We have passwords for emails, databases, computer systems, servers, bank accounts, and virtually everything that we want to protect. Passwords are in general the keys to get access into a system or an account.In general, people tend to set passwords that are easy to remember, such as their date of birth, names of family members, mobile numbers, etc. This is what makes the passwords weak and prone to easy hacking.One should always take care to have a strong password to defend their accounts from potential hackers. A strong password has the following attributes −Contains at least 8 characters.A mix of letters, numbers, and special characters.A combination of small and capital letters.Password cracking is the most enjoyable hacks for bad guys. It increases the sense of exploration and useful in figuring out the password. The password cracking may not have a burning desire to hack the password of everyone. The actual password of the user is not stored in the well-designed password-based authentication system. Due to this, the hacker can easily access to user's account on the system. Instead of a password, a password hash is stored by the authentication system. The hash function is a one-way design. It means it is difficult for a hacker to find the input that produces a given output. The comparison of the real password and the comparison of two password hash are almost good. The hash function compares the stored password and the hash password provided by the user. In the password cracking process, we extract the password from an associated passwords hash. Using the following ways, we can accomplish it and you will learn that skills in this course:XHydraCracking SSHNcrackUsing Word ListCrunchAdvance Password Hacking
