作者: HAT 时间: 2007-9-16 13:25 标题: [已结]怎样用批处理生成一个纯字母的密码字典
我想用批处理来生成一个纯字母（可以只考虑小写字母）的密码字典，用户输入密码长度，自动生成字典文件dictionary.txt
如果输入3，则dictionary.txt的内容如下：
| Quote: | |
|
如果输入4，则dictionary.txt的内容如下：
| Quote: | |
|
望高人指点。

如果楼主要求不高的话
看看这个
你可以改一下
这个并没有做到把26个字母做全排列!
@echo off
setlocal enabledelayedexpansion
set tb=abcdefghijklmnopqrstuvwxyz
set/p in=" 输入密码位数N: "
for /l %%i in (1,1,!in!) do (
for /l %%a in (0,1,25) do (
set /a n+=1
set /a m=%%a-!random:~0,1!
if !m! lss 0 set /a m=-m
if !n! leq !in! (call :out !n! !m!) else (set/a n=0&echo.>>dic.txt)
)
)
echo.
start dic.txt
endlocal
pause&exit/b
:out
>>dic.txt set/p out=!tb:~%2,1!<nul
setlocal enabledelayedexpansion
set tb=abcdefghijklmnopqrstuvwxyz
set/p in=" 输入密码位数N: "
for /l %%i in (1,1,!in!) do (
for /l %%a in (0,1,25) do (
set /a n+=1
set /a m=%%a-!random:~0,1!
if !m! lss 0 set /a m=-m
if !n! leq !in! (call :out !n! !m!) else (set/a n=0&echo.>>dic.txt)
)
)
echo.
start dic.txt
endlocal
pause&exit/b
:out
>>dic.txt set/p out=!tb:~%2,1!<nul

如果向得到更多的话
可以改一改:
for /l %%i in (1,1,!in!) do
为
for /l %%i in (1,1,!n!!in!) do
不过要小心,!n!!n!太多了,运行会耗时间的

将代码稍改一下tb
tb=abcdefghijklmnopqrstuvwxyz0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ
可以有大小写和数字
不过这个程序写的不好啊!

输入1的时候，结果不对：
b
b
c
e
g
h
i
n
o
p
r
v
x

嗯,是的
我这个只是随机输出
我说过了
它并没有解决26个字母的全排列问题
你可以尝试着解决一下
思路有很多
不一定我的就是好的e

试了下面这段4位的，在我机子（3G CPU）上从aaaa到zzzz得花一分钟左右（不显示echo部分），所以想用批处理的出这样的字典还是算了吧
@echo off
set "str=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"
for %%a in (%str%) do (
for %%c in (%str%) do (
for %%e in (%str%) do (
for %%g in (%str%) do (
echo %%a%%c%%e%%g
)
)
)
)
pause
exit
给段10位以内的：set "str=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"
for %%a in (%str%) do (
for %%c in (%str%) do (
for %%e in (%str%) do (
for %%g in (%str%) do (
echo %%a%%c%%e%%g
)
)
)
)
pause
exit
@echo off
set "str=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"
for /l %%n in (1,1,10) do (
set for%%n=rem
set display%%n=
)
set num=
set /p num= 输入密码位数N (1≥N≥10):
for /l %%n in (1,1,%num%) do set for%%n=
echo.
set time_=%time%
for %%a in (%str%) do (set display1=%%a
%for2% for %%c in (%str%) do (set display2=%%c
%for3% for %%e in (%str%) do (set display3=%%e
%for4% for %%g in (%str%) do (set display4=%%g

%for8% for %%o in (%str%) do (set display8=%%o
%for9% for %%q in (%str%) do (set display9=%%q
%for10% for %%s in (%str%) do (set display10=%%s
call echo.%%display1%%%%display2%%%%display3%%%%display4%%%%display5%%%%display6%%%%display7%%%%display8%%%%display9%%%%display10%%
%for2% )
%for3% )
%for4% )
%for5% )
%for6% )
%for7% )
%for8% )
%for9% )
%for10% )
)
echo.
echo %time_%

没有比一层一层写for循环更高效的算法吗？
