Tags: linux commandsUseLinuxcommand to generate random passwords is a basicLinuxoperation function, and there are many forms of implementation, the specific use of the following:1. generate random passwords using OpenSSLThe specific usage is as follows:OpenSSL rand-base64 20almost all Linux distributions include OpenSSL. We can use its random function to generate a random letter string that can be used as

If exists (select * From DBO. sysobjects where id = object_id (n' [DBO]. [p_getpassword] ') and objectproperty (ID, n' isprocedure') = 1) Drop procedure [DBO]. [p_getpassword] Go /* -- Brute-force cracking SQL Server user password Attackers can crack passwords with Chinese characters, special characters, characters, and trailing spaces. For the convenience of displaying passwords with special characters,

Often people generate passwords are confused, one is not enough complexity will be unsafe, enough complexity and can not manually hit the keyboard to play together characters (but usually these characters are regular),Use 1password or keepass This software generation can also, but looks like 1password to charge, since so we play a fun to use Linux to generate random passwords to play it;One of the great adv

Before writing a shell to generate random passwords, in order to follow more automation, part of the work has been transferred to the automation of Python processing, so many of the original shell tools have to be transformedThe following is written by Python to generate random passwords, the use of knowledge points are: Random used to generate random numbers, Sys used to get the parameters of the command l

Although attacks caused by easy-to-guess passwords often appear in the headlines of the media, the current password cracking system is already very advanced, it can even crack the password created by a seemingly complex notebook device. By using a ready-made graphics processor for cheap parallel computing, the current cracking technology can guess trillions of combinations of passwords every hour. Steve Tho

Due to the leakage of csdn passwords, everyone has been paying attention to the security of their Internet accounts, which has long existed, but this time it has been exposed. The reason for storing passwords in plaintext is analyzed below. Transferred from Http://shell909090.com/blog/2011/12/%e5%af%86%e7%a0%81%e4%b8%ba%e4%bb%80%e4%b9%88%e6%98%8e%e6%96%87%e5%ad%98%e6%94%be/ I wrote a blog long ago and said

Introduction to forcible use of more complex passwords I recently read a blog post (bole online Note: Please refer to the end of this article) about forcible use of more complex passwords. The original author said this is for safety, but I don't think these technologies are the best way to do it. It seems very troublesome than "practical.Problem You want to implement a safer password, I understand. However,

Basic knowledgeThe password for the Linux user is implemented by the function crypt (). Crypt () is a cryptographic function (password encryption, plaintext into ciphertext), the function is based on the Data Encryption Standard (DES,DATA encryption) algorithm and DES-based other variant algorithm, the function does not rely on computer hardware to achieve data encryption. The DES algorithm is only suitable for encrypting strings, that is, for generating pas
