如何从这个十六进制数读取数据？ [英] How to read data from this hex number?
问题描述
我想学习如何读取十六进制数字的数据。这是我的照片： Imgur：互联网上最棒的图片 [ ^ ]。如何看待
位， byte ，字符串，endianess，？你能从我的照片中读到什么？这是我的文件，我在hex workshop workshop编辑器中打开它： RPP_02.pp - Google Drive [ ^ ]
请帮忙？告诉我怎么读它？
我尝试过：
i什么都不知道。我只是这个领域的初学者。我的观点是扭转归档游戏文件。我已经开始在youtube上找到，发现https://www.youtube.com/watch?v=bOl7jGfossI，我也发布了这个：http：//zenhax.com/viewtopic.php？f = 13& t = 3034。我仍然没有得到正确的答案。
老实说，如果你无法弄清楚十六进制编辑器如何显示数据，那么你可能会尝试承担超出当前技能的任务：图片显示左侧的十六进制字节视图的标准十六进制编辑器（每个字节分别显示为两位十六进制数字）和右侧的字符视图（其中相同的字节显示为可见字符，它们在ASCII标准字符集可打印范围内，如果不是，则显示为。。
位不显示，因为它们有八个字节，并且需要太多空间：虽然转换并不困难，但每个十六进制数字值转换为一组四个二进制数字：
< pre lang =text> 0 0000
1 0001
2 0010
3 0011
4 0100
5 0101
6 0110
7 0111
8 1000
9 1001
A 1010
B 1011
C 1100
D 1101
E 1110
F 1111
和几乎，十六进制编辑器不能告诉你Endianness，除非你知道某些值的范围和大小（假设所有值都是相同的大小，但事实并非如此）：四个字节01 00 00 00可能是以多种方式读取 - 从1作为一个小的Endian 32位数字到16,777,216作为Big Endian 32位数，通过两个16位数字，四个8位数字或64位数字的一半！
加上......逆向工程游戏文件很可能违反了你的许可协议，而且即使它不是，也保证很简单：manny是压缩的所以你是什么看到的不是你得到的，一个微不足道的变化可以打破整个文件。
如果我是你，我会玩游戏，并且变得更好在它 - 它可能比尝试更容易o反向存档文件并作弊！ ：笑：
Hex编辑器只显示二进制包含文件，甚至是不可显示的数据。
关于数据的含义，你必须设计它。问题在于它是经验问题。
建议：实验！
- 在NotePad中创建带文本的文件，然后打开在Hex编辑器中然后比较两边，匹配它们不应该很复杂。
- 之后，你需要构建或找到一个已知二进制数据的文件，然后你必须研究显示器来设计什么是什么。
I want to learn how to read data in hex number. this is my picture : Imgur: The most awesome images on the Internet[^] . how to see something like
bits, byte, strings, endianess, ?? what you can read from my picture?? here is my file and i opened it in hex workshop editor :RPP_02.pp - Google Drive[^]
please help?? tell me how to read it??
What I have tried:
i don't know nothing. i just a beginner in this field. my point is reversing archive game file. i have start find on youtube, found https://www.youtube.com/watch?v=bOl7jGfossI , i also post this : http://zenhax.com/viewtopic.php?f=13&t=3034 .I still don't get correct answer.
To be honest, if you can't work out how a hex editor shows data, then you're probably trying to take on a task that is way beyond your current skill set: the picture shows a "standard" hex editor with hex byte view on the left (where every byte is displayed separately as a two digit hexadecimal number) and a character view on the right (where the same bytes are shown as visible characters in they are in the ASCII standard character set "printable" range, and as a '.' if they aren't.
Bits it doesn't show, as there are eight of them to a byte and it would take too much space: it isn't difficult to convert though, each hex digit value translates to a single set of four binary digits:
0 0000 1 0001 2 0010 3 0011 4 0100 5 0101 6 0110 7 0111 8 1000 9 1001 A 1010 B 1011 C 1100 D 1101 E 1110 F 1111
And pretty much, a hex editor can't tell you Endianness unless you know the range and size of some of the values (assuming all values are the same size, which just isn't the case): four bytes 01 00 00 00 could be read in many, many ways - from "1" as a little Endian 32 bit number to 16,777,216 as a Big Endian 32 bit number, via two 16 bit numbers, four 8 bit numbers, or half of a 64 bit number!
Plus... reverse engineering game files is quite possibly in breach of your licensing agreements, and hot guaranteed to be simple even it it wasn't: manny are compressed so what you see is not what you get, and a trivial change can "break" the whole file.
If I was you, I'd play the game, and get better at it - it's probably easier than trying to reverse archive files and cheat! :laugh:
An Hex editor just show you the binary contain of a file, even non displayable data.
Concerning the meaning of the data, you have to devise it. The problem is that it is a matter of experience.
Advice: experiment!
- Create a file with text in NotePad, then open in Hex editor then compare both sides, matching them should not be complicated.
- After that, you need to build or find a file with known binary data, then you have to study the display to devise what is what.
