如何批量制作字母密码生成器？

10

我很难弄清楚如何制作一个带有随机字母的密码生成器。例如，ASWED-ASDWAD-EFEST。到目前为止，我只能使用代码来随机数

@echo off

:password

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

PS：我的操作系统是Windows Vista。

所有帮助将不胜感激。

我在Windows NT中将cmd.exe添加了％RANDOM％。很高兴看到它仍然有用。

有一个讨论，在这里，你可以为你的目的相适应。

@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解释了以上内容：

我已经对其进行了修改，因此您可以轻松指定长度并添加或删除字符，而无需更改代码的任何其他部分。

例如，您可能不想同时使用0和O（零和大写O）或1和l（一个小写L）。

除以下字符外，您可以使用标点符号：

! % ^ & < >

您可以使用^and %，但必须在_Alphanumeric 变量中两次输入^^或%%。但是，如果您想_RndAlphaNum稍后在批处理文件中使用结果（）（而不是回显屏幕），则可能需要特殊处理。

您甚至可以使用空格，只要它不是字符串中的最后一个字符即可。但是，如果它以生成的字符串中的最后一个字符结尾，则不会使用它，因此您只有7个字符。

感谢您的帮助，我是一批新手，所以我想知道您是否可以帮助我解释您显示给我的代码。我想简化它，以便可以看到是什么代码精确生成了随机字母。

这些似乎是主要的非解释性行：Set /A _RND=_RND%%61-_RND先前被设置为随机数，然后对其进行模数61，以得到0到61之间的数字。SET _rndalphanum=!_Alphanumeric:~%_RND%,1! 然后，它在_RND位置为_Alphanumeric的子字符串1个字符。因此，它正在选择一个介于0到61之间的数字，然后从A-Za-z中提取该字符。然后，您可以通过重复该过程来构建随机字符的alpha字符串。

这是一个简单而优雅的解决方案

@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

这可以工作，但是当我们将其作为sub调用时，它的行为并不正确。（即，当您调用子例程：generator时，意外发生故障。

这是一个完整的版本，具有16个字符，包括大写，小写和数字。这是一个新手版本，因此它不包含“ for”之类的任何复杂命令，但效果很好。如果生成的行过多，它可能会滞后并偶尔停止工作，这只是缺点。
