## Breaking Wifi password knowing its length of 8 [A-Z] alpha (upper-case) characters using Hashcat

I got the WPA handshake, now it’s turn to crack the password using Hashcat. First, I wanted to make a wordlist of passwords [A-Z] the length of 8, but Crunch (the tool in Kali Linux) said it will take 1TB of storage that I don’t have available, so I gave up that way. Is there any way to generate passwords (example: ABCDEFGH) and delete them after its use one by one, during the cracking process?

How long does it take to crack the password with i5-3320M CPU using Hashcat? Is there any other way you recommend?

## UPPERCASE Constraint in SQL

What will be the query to add UPPERCASE Constraint to a column of pre-existing table? The question demands to ensure that the entries are in UPPERCASE.

## List all entries in the current directory whose names contain only uppercase letters

In one of my lab questions I was asked to list all entries(both files and folders) in the current directory whose names contain only uppercase letters using piping and grep command. Folders must have a forward slash displayed. Initially, my solution looked like this:

``ls -p | grep -e "^[[:upper:]]*\/?\$  " ``

I thought that I can protect the ‘/’ sign with the backward slash(as in `echo \*` vs `echo *`). However, it doesn’t work as intended. One of my friends suggested the following solution:

``ls -p | grep -e '^[[:upper:]]*/\?\$  ' ``

I have no idea why the backward slash is used like this. What is even more weird,for me, that it actually produces the right result. I was wondering if someone could explain where the mistake in my solution is and why the second version actually works.

## How to see tables and column names in exact case which is created and not by default uppercase?

In toad, whenever I create an object such as a table, If I name columns in PascalCase when it created if I open the table, then toad displays all the column names in uppercase.

Is there any option in toad which prevents this default behavior and let us see the object names in the exact case which we create them?

## Why in any installation prompt (Y/n) the ‘Y’ is in Uppercase and the ‘n’ in lowercase?

The question itself is self explanatory. As another query I would like to know if it’s possible to replace the ‘Y’ option with ‘Enter’ keystroke.

## Uppercase to lowercase rel canonical

There is a section of our site where the url’s are automatically generated based on the title of the page. This includes capitalisation.

When using Screaming Frog I noticed that a capitalised and non-capitalised verison of many o fthese pages were "indexable". Therefore I want to add in a rel canonical so that one of the versions of the page is recognised as the primary indexable version.

My question is this: if the CMS is generating a capitalised version automatically, should the capitalised version of the page be the canonical page, or should it be the non-capitalised vesion?

Thanks,

Sam.

## Generating 10-character passwords, with 3-6 digits and 3-6 uppercase letters, in C++

In response to a question on Information Security on brute-forcing passwords, I wrote code that helped solve the problem:

Generate a password list of 10 character passwords containing only a combination of 3 – 6 numbers and 3 – 6 uppercase letters.

I’d like a code review done of the snippet I wrote. I don’t know really anything about optimizing software. I can write it (self-taught) but I don’t have the deep insights needed to improve already working software, so I’ve started posting code snippets in here for you guys to give me insights. I really think this channel is great and without further ado, I’ll get to it.

``#include <iostream> #include <vector> #include <random> #include <string>  const char charset[] = {'A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z','0','1','2','3','4','5','6','7','8','8','9'}; int main() {      std::cout << "Please enter the number of passwords to generate here: ";     int num_pass;     std::cin >> num_pass;     std::random_device dev;     std::mt19937_64 rng(dev());     std::vector<std::string> passwds;     std::uniform_int_distribution<std::mt19937_64::result_type> dist(0, sizeof(charset) - 1);      for (int i = 0; i < num_pass; ++i) {         std::string pass = "";         int num_nums = 0, num_chars = 0;         while (pass.length() < 10) {             char c = charset[dist(rng)];             if (isdigit(c) && num_nums < 6) {                 pass += c;                 num_nums++;             }             else if (isalpha(c) && num_chars < 6) {                 pass += c;                 num_chars++;             }         }         passwds.push_back(pass);         std::cout << pass << std::endl;     }     std::cin.get(); } $$```$$ ``

## Sharepoint list column uppercase validation

So I’m basically trying to validate a column in my SharePoint list to have a Specific letter as the starting character of the field. I’m running into an issue with capitalization. I need the first character to be only uppercase. This is what I currently have but it is not validating for only uppercase. (67 is the ascii code for the letter “c”). Thank you!

``CODE(MID([Column Name],1,1)=UPPER(67)) ``

## Como transformar palavras em uppercase, através da captura de regex [pendente]

Boa tarde pessoa, tenho o seguinte objeto js e queria transforma tudo que estiver no atributo ‘header’ em uppercase.

`campos: [ { nome: 'REPLACE(fmrf_polo, \'"\', \'\') fmrf_polo', header: 'codigo_polo', }, { nome: 'REPLACE(fmrf_pold, \'"\', \'\') fmrf_pold', header: 'nome_polo', }, { nome: 'REPLACE(fmrf_cids, \'"\', \'\') fmrf_cids', header: 'cidadepolo', }, { nome: 'REPLACE(fmrf_abbi, \'"\', \'\') fmrf_abbi', header: 'ano_inicio_polo', } ]`
