ランダムな文字を含むパスワードジェネレータを作成する方法を理解するのに苦労しています。たとえば、ASWED-ASDWAD-EFEST。これまでのところ、コードを使用して乱数を作成することができます
@echo off
:password
echo %random%-%random%-%random
pause
goto password
PS:私のOSはWindows Vistaです。
すべての助けをいただければ幸いです。
here を議論して、目的に合わせて調整することができます。

TheOutcaste は上記を説明しています:
コードを変更したので、コードの他の部分を変更せずに、簡単に長さを指定して文字を追加または削除できます。
たとえば、0とO(ゼロと大文字のO)、または1とl(1つと小文字のL)の両方を使用したくない場合があります。
次の文字を除いて句読点を使用できます。
! % ^ & < >
^
および%
を使用できますが、_Alphanumeric
変数に^^または%%
として2回入力する必要があります。ただし、結果(_RndAlphaNum
)を後でバッチファイルで使用する場合(画面へのエコー以外)、特別な処理が必要になる場合があります。文字列の最後の文字でない限り、スペースを使用することもできます。ただし、生成された文字列の最後の文字として使用される場合は使用されないため、7文字しかありません。
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%
これはこれに対するシンプルでエレガントなソリューションです
@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

これは機能しますが、subとして思い出すと正しく機能しません。 (つまり、サブルーチン:generatorを呼び出すと、予期せぬ誤動作が発生します。
