如何更改文件字节? [英] how can I change a file bytes?

问题描述

大家好，我想知道我是否更改了文件的位数组或字节(改变位置或值)，该文件将不可读，是否意味着该文件已成为加密文件?谁能引导我阅读文章或书籍，以了解什么是文件，如何在计算机操作系统中表示该文件.请任何帮助将不胜感激.
感谢您阅读我的问题.

Hi every body , I wonder if I changed the file bits array or bytes (changing positions or values) would the file be unreadable, dose it mean that the file became an encrypted file?. can any one guide me to articles or books to understand what is a file, how it is represented in the computers os. please any help will be appreciated.
thanks for reading my Question.

推荐答案

是否表示该文件已成为加密文件?"
否.这意味着它已损坏.

加密是特定过程的名称:转换信息，以便不使用用于转换信息的密钥值来逆转该过程就无法理解信息.仅仅弄乱值和位置就不太可能对文件进行加密，只会损坏文件.

什么是文件?使用一些定义的编码机制将位"A"与内部格式(十六进制)相关联的位序列，通常按组排列以表示字节或字符(可以是6位，7位，8位，16位或32位) ASCII 7或8位为41)等.

在那之后，文件的实际位置变得有些复杂.您想找出什么?

"dose it mean that the file became an encrypted file?"
No. It means it becomes a corrupted file.

Encryption is a name for a specific process: transforming information so that it cannot be understood without reversing the process using the key value that was used to transform it. Just messing about with values and positions is very unlikely encrypt a file, it just damages it.

What is a file? A sequence of bits, normally arranged into groups to represent bytes or characters (which may be 6 bit, 7 bit, 8 bit , 16 bit or 32 bit) using some defined encoding mechanism which relates an "A" to the internal form (hexadecimal 41 in ASCII 7 or 8 bit) and so on.

After that, it gets a bit complicated as to what a file actually is. What are you trying to find out?
