三菱 PLC FX3U解密研究
价格:100.00
三菱PLCFX3U解密研究我是从2010年5月26日开始研究FX3U解密,查遍网络找不到只言半语,看来FX3U解密没人研究,或者研究的人怕人家学,竟然找不到一丁点有用的信息。看来只有靠自力更生了。虽然目前已经研究成功了FX3U解密,免拆机的,读出正确程序和参数,包括禁止上载的问题也能读出正确程序和参数。但我还是想把当时研究解密的过程整理出来,供有兴趣的朋友参考,我这里所讲的过程也是我实践研究的过程,这当中也难免要走弯路的。但最终是要通往成功的大道的。其实没必要搞得这么神秘,PLC解密没那么复杂。1、三菱PLCFX3U用的编程软件必须采用GXDeveloper8.10以上的版本,我是从网上下载个GXDeveloperVersion8.52E就可以支持FX3U的编程。启动GXDeveloper,从帮助菜单就可以看到编程软件的版本号,如下图所示。从工程菜单,创建新工程,PLC系列中选择FXCPU,PLC类型中选FX3U(C)就可以对FX3U进行编程的各种操作。2、FX3U的加密方法是:打开GXDeveloper后从菜单"在线—》登录关键字—》新建登录,改变....."进入,显示如下界面:FX3U可以设置两个密码,即关键字和第2关键字,每个有8个字符(字符只能是0-F共16个16进制的字符),这样说明如果两个关键字都设定的话密码总共有16个字符。这样可以组合多少种密码呢,即16^16=18446744073709551616.这是个天文数字,有人想要用穷举法解密,那是不可能的。3、首先随便编个测试程序,不加密,两个关键字都不设定,写入FX3U,然后用FXWIN软件选取FX2N型号读出程式,竟然能读出正确的程序来。相信三菱FXPLC的FXWIN程软件大家应该很熟悉了。界面如下所示:用自编的FX三菱解密软件连线显示,FX3UPLC竟然显示成FX2N版本号为2.41,说明FX3U是FX2N的高级版本。4、继续测试,用GXDeveloper只设定第1关键字,第2关键字为空。用自编的FX三菱解密软件(可解FX0N、1N、2N、1S、FX2),进行解密。竟然解出密码来。按FX2N型号进行下载也能下载程序,说明当只设一个关键字的时候,FX3U加密机制和FX2N的是一模一样的。看看我的FX解密软件:5、继续测试,用GXDeveloper同时设定第1关键字,第2关键字。这时用老的解密软件解不出来了,用老的编程软件FXGP-WIN-C,企图读入程序,显示通信错误。6、看来只有祭出法宝了,那就是PLC解密通用的法宝串口监控软件。先启用串口监控软件,设置好开始监控,然后运行编程软件。注意顺序要搞对喔。从菜单-》在线-》传输设置,进入传输设置界面,然后“按通信测试”键,显示CPU类型为FX3U,通信成功。此时从串口监控到的数据是:#TimeFunctionData(Hex)1[00000000]IRP_MJ_CREATEPortOpened-Gppw.exe2[00000000]IOCTL_SERIAL_SET_BAUD_RATEBaudRate:1152003[00000000]IOCTL_SERIAL_SET_LINE_CONTROLStopBits:1,Parity:Even,DataBits:74[00000001]IRP_MJ_WRITELength:0001,Data:055[00000002]IRP_MJ_READLength:0001,Data:066[00000002]IRP_MJ_WRITELength:0011,Data:02303045303230320336437[00000003]IRP_MJ_READLength:0001,Data:028[00000003]IRP_MJ_READLength:0001,Data:429[00000003]IRP_MJ_READLength:0001,Data:3110[00000003]IRP_MJ_READLength:0001,Data:3511[00000003]IRP_MJ_READLength:0001,Data:4512[00000003]IRP_MJ_READLength:0001,Data:0313[00000003]IRP_MJ_READLength:0001,Data:4614[00000003]IRP_MJ_READLength:0001,Data:3015[00000004]IRP_MJ_WRITELength:0011,Data:023030454341303203384516[00000004]IRP_MJ_READLength:0001,Data:0217[00000004]IRP_MJ_READLength:0001,Data:3718[00000004]IRP_MJ_READLength:0001,Data:3119[00000004]IRP_MJ_READLength:0001,Data:3320[00000004]IRP_MJ_READLength:0001,Data:4621[00000004]IRP_MJ_READLength:0001,Data:0322[00000004]IRP_MJ_READLength:0001,Data:4523[00000004]IRP_MJ_READLength:0001,Data:3424[00000005]IRP_MJ_WRITELength:0011,Data:023030453032303203364325[00000006]IRP_MJ_READLength:0001,Data:0226[00000006]IRP_MJ_READLength:0001,Data:4227[00000006]IRP_MJ_READLength:0001,Data:3128[00000006]IRP_MJ_READLength:0001,Data:3529[00000006]IRP_MJ_READLength:0001,Data:4530[00000006]IRP_MJ_READLength:0001,Data:0331[00000006]IRP_MJ_READLength:0001,Data:4632[00000006]IRP_MJ_READLength:0001,Data:3033[00000006]IRP_MJ_WRITELength:0011,Data:023030454341303203384534[00000007]IRP_MJ_READLength:0001,Data:0235[00000007]IRP_MJ_READLength:0001,Data:3736[00000007]IRP_MJ_READLength:0001,Data:3137[00000007]IRP_MJ_READLength:0001,Data:3338[00000007]IRP_MJ_READLength:0001,Data:4639[00000007]IRP_MJ_READLength:0001,Data:0340[00000007]IRP_MJ_READLength:0001,Data:4541[00000007]IRP_MJ_READLength:0001,Data:3442[00000015]IRP_MJ_CLOSEPortClosed开始花大量时间来分析这些数据吧。上述从串口监控到的数据是十六进制的数据,还真不好看,先转换成ASC码,就好看多了。#TimeFunctionData(String)1[00000000]IRP_MJ_CREATEPortOpened-Gppw.exe2[00000000]IOCTL_SERIAL_SET_BAUD_RATEBaudRate:1152003[00000000]IOCTL_SERIAL_SET_LINE_CONTROLStopBits:1,Parity:Even,DataBits:74[00000001]IRP_MJ_WRITELength:0001,Data:5[00000002]IRP_MJ_READLength:0001,Data:6[00000002]IRP_MJ_WRITELength:0011,Data:00E02026C7[00000003]IRP_MJ_READLength:0001,Data:8[00000003]IRP_MJ_READLength:0001,Data:B9[00000003]IRP_MJ_READLength:0001,Data:110[00000003]IRP_MJ_READLength:0001,Data:511[00000003]IRP_MJ_READLength:0001,Data:E12[00000003]IRP_MJ_READLength:0001,Data:13[00000003]IRP_MJ_READLength:0001,Data:F14[00000003]IRP_MJ_READLength:0001,Data:015[00000004]IRP_MJ_WRITELength:0011,Data:00ECA028E16[00000004]IRP_MJ_READLength:0001,Data:17[00000004]IRP_MJ_READLength:0001,Data:718[00000004]IRP_MJ_READLength:0001,Data:119[00000004]IRP_MJ_READLength:0001,Data:320[00000004]IRP_MJ_READLength:0001,Data:F21[00000004]IRP_MJ_READLength:0001,Data:22[00000004]IRP_MJ_READLength:0001,Data:E23[00000004]IRP_MJ_READLength:0001,Data:424[00000005]IRP_MJ_WRITELength:0011,Data:00E02026C25[00000006]IRP_MJ_READLength:0001,Data:26[00000006]IRP_MJ_READLength:0001,Data:B27[00000006]IRP_MJ_READLength:0001,Data:128[00000006]IRP_MJ_READLength:0001,Data:529[00000006]IRP_MJ_READLength:0001,Data:E30[00000006]IRP_MJ_READLength:0001,Data:31[00000006]IRP_MJ_READLength:0001,Data:F32[00000006]IRP_MJ_READLength:0001,Data:033[00000006]IRP_MJ_WRITELength:0011,Data:00ECA028E34[00000007]IRP_MJ_READLength:0001,Data:35[00000007]IRP_MJ_READLength:0001,Data:736[00000007]IRP_MJ_READLength:0001,Data:137[00000007]IRP_MJ_READLength:0001,Data:338[00000007]IRP_MJ_READLength:0001,Data:F39[00000007]IRP_MJ_READLength:0001,Data:40[00000007]IRP_MJ_READLength:0001,Data:E41[00000007]IRP_MJ_READLength:0001,Data:442[00000015]IRP_MJ_CLOSEPortClosed从上面数据看到,其实只有四个回合的数据通信,其中还有两个回合是一模一样的重复的数据。分析如下:电脑发:00E0202’查询D8001的值P
