como você faz um gerador de senha de letra em lote?

Question

Estou tendo dificuldades para descobrir como criar um gerador de senhas com letras aleatórias. Por exemplo, ASWED-ASDWAD-EFEST. Até agora só posso fazer números aleatórios usando o código

@echo off

:password

echo %random%-%random%-%random
pause
goto password

PS: meu sistema operacional é o Windows Vista.

toda ajuda será apreciada.

    

Answer 1

Existe uma discussão aqui que você pode adaptar para seus objetivos.

@Echo Off
Setlocal EnableDelayedExpansion
Set _RNDLength=8
Set _Alphanumeric=ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789
Set _Str=%_Alphanumeric%987654321
:_LenLoop
IF NOT "%_Str:~18%"=="" SET _Str=%_Str:~9%& SET /A _Len+=9& GOTO :_LenLoop
SET _tmp=%_Str:~9,1%
SET /A _Len=_Len+_tmp
Set _count=0
SET _RndAlphaNum=
:_loop
Set /a _count+=1
SET _RND=%Random%
Set /A _RND=_RND%%%_Len%
SET _RndAlphaNum=!_RndAlphaNum!!_Alphanumeric:~%_RND%,1!
If !_count! lss %_RNDLength% goto _loop
Echo Random string is !_RndAlphaNum!

TheOutcaste explica o acima:

I've modified it so you can easily specify the length and add or remove characters without having to change any other part of the code.

For example, you might not want to use both 0 and O (zero and Uppercase O), or 1 and l (one and lowercase L).

You can use punctuation except for these characters:

! % ^ & < >

You can use ^ and %, but must enter them in the _Alphanumeric variable twice as ^^ or %%. However, if you want to use the result (_RndAlphaNum) later in the batch file (other than Echoing to the screen), they might require special handling.

You can even use a space, as long as it's not the last character in the string. If it ends up as the last character in the generated string though, it will not be used, so you would only have 7 characters.

    

Answer 2

rem 16 stings pwd

setlocal ENABLEEXTENSIONS ENABLEDELAYEDEXPANSION
set alfanum=ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789

set pwd=
FOR /L %%b IN (0, 1, 16) DO (
SET /A rnd_num=!RANDOM! * 62 / 32768 + 1
for /F %%c in ('echo %%alfanum:~!rnd_num!^,1%%') do set pwd=!pwd!%%c
)

echo pwd=%pwd%

aqui é meu. Ameture, mas funciona

@Echo OFF
@echo Would You Like Me To Make You A Password? Type Your Response And Press Enter.
set /p ans=
if %ans%==yes (goto yes
)
if %ans%==no (goto exit
)

:exit
cls
@echo Are You Sure?
set /p ans=
if %ans%==yes (goto exit
)
if %ans% NEQ yes (goto yes
)
:yes
cls 
@echo Loading...

@echo OFF
ping localhost -n 4 > Nul

Answer 4

Eu editei um pauls:

@Echo Off
color 0a
set /P lengthnumberuser="What length do you want your password to be?   "
pause
cls
Setlocal EnableDelayedExpansion
Set _RNDLength=%lengthnumberuser%
Set _Alphanumeric=ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789
Set _Str=%_Alphanumeric%987654321
:_LenLoop
IF NOT "%_Str:~18%"=="" SET _Str=%_Str:~9%& SET /A _Len+=9& GOTO :_LenLoop
SET _tmp=%_Str:~9,1%
SET /A _Len=_Len+_tmp
Set _count=0
SET _RndAlphaNum=
:_loop
Set /a _count+=1
SET _RND=%Random%
Set /A _RND=_RND%%%_Len%
SET _RndAlphaNum=!_RndAlphaNum!!_Alphanumeric:~%_RND%,1!
If !_count! lss %_RNDLength% goto _loop
Echo Password is: is !_RndAlphaNum!

pause

    

Answer 5

:generator
@Echo Off
Setlocal EnableDelayedExpansion
Set _RNDLength=8
Set _Alphanumeric=ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789
Set _Str=%_Alphanumeric%987654321
:_LenLoop
IF NOT "%_Str:~18%"=="" SET _Str=%_Str:~9%& SET /A _Len+=9& GOTO :_LenLoop
SET _tmp=%_Str:~9,1%
SET /A _Len=_Len+_tmp
Set _count=0
SET _RndAlphaNum=
:_loop
Set /a _count+=1
SET _RND=%Random%
Set /A _RND=_RND%%%_Len%
SET _RndAlphaNum=!_RndAlphaNum!!_Alphanumeric:~%_RND%,1!
If !_count! lss %_RNDLength% goto _loop
Echo Random string is !_RndAlphaNum!

Isso funciona, mas não funciona bem quando nos lembramos dele como sub. (isto é, mau funcionamento imprevisível quando você chama a sub-rotina: gerador.
