come si crea un generatore di password per le lettere in batch?

Sto facendo fatica a capire come creare un generatore di password con lettere casuali. Ad esempio, ASWED-ASDWAD-EFEST. Finora posso solo fare numeri casuali usando il codice

@echo off

:password

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

PS: il mio sistema operativo è Windows Vista.

tutto l'aiuto sarà apprezzato.

C'è una discussione qui che potresti adattare ai tuoi scopi.

@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 spiega quanto sopra:

L'ho modificato in modo da poter specificare facilmente la lunghezza e aggiungere o rimuovere caratteri senza dover modificare altre parti del codice.

Ad esempio, potresti non voler utilizzare sia 0 che O (zero e O maiuscola) o 1 e l (una e L minuscola).

È possibile utilizzare la punteggiatura ad eccezione di questi caratteri:

! % ^ & < >

È possibile utilizzare ^e %, ma è necessario immetterli nella _Alphanumeric variabile due volte come ^^ o %%. Tuttavia, se si desidera utilizzare il risultato ( _RndAlphaNum) in un secondo momento nel file batch (diverso dall'eco per lo schermo), potrebbe richiedere una gestione speciale.

Puoi persino usare uno spazio, purché non sia l'ultimo carattere della stringa. Se finisce come l'ultimo carattere nella stringa generata, non verrà usato, quindi avresti solo 7 caratteri.

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%

Questa è una soluzione semplice ed elegante per questo

@echo off
setlocal enableextensions enabledelayedexpansion

set /P _length=Password Length: %==%
set /a z = %_length%
set "string=ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789"
set "password="
for /L %%i in (1,1,!z!) do call :_genRand
echo Password is:  %password%
goto :EOF

:_genRand
set /a x=%random% %% 62
set password=%password%!string:~%x%,1!
goto :eof

ecco il mio. Ameture, ma funziona

Funziona ma non si comporta bene quando lo ricordiamo come sub. (ovvero malfunzionamenti imprevedibili quando si chiama la subroutine: generatore.

Questa è una versione completamente realizzata con 16 caratteri inclusi lettere maiuscole, minuscole e numeri. È una versione da principiante, quindi non include comandi complessi come "for", ma funziona bene. L'unico inconveniente è che può essere ritardato e occasionalmente smettere di funzionare se si generano troppe linee.
