C ++ MD5 operations (including source code download)

Although some C ++ third libraries have inherited the MD5 operation, sometimes we need a lightweight MD5 library function. Here we provide an MD5 class that can pass in a string to generate the MD5 result.

MD5 library download

After downloading and unzipping, there are three files: md5.h md5.cpp main. cpp, where md5.h and md5.cpp are MD5 Class header files and implementation files, and Main. cpp is a test file.

Compile and run

 
G ++ md5.cpp main. cpp-O main
./Main
 

Output result:

 
ABC MD5Is900150983cd24fb0d6963f7d28e17f72
 

The content of the Main. cpp file is also an example of MD5 class usage, as follows:

# Include"Md5.h"
# Include <String>
# Include <iostream>
IntMain (){
Using NamespaceSTD;
StringSTR ="ABC";
MD5 MD5 (STR );
StringResult = md5.md5 ();
Cout <"ABC MD5 is"<Result <Endl;
Return 0;
}
