Modify the name of the dynamic library file that OpenSSL compiles by default

There are two ways to invoke a dynamic-link library DLL file on a Windows platform:A) implicit load-time linking; use the *.lib (import library) file to include the name of the import library lib file in the IDE's linker related settings, or add the precompiled Directive #pragma comment (lib, "*.lib") to the program.b) Explicit run-time linkage. Instead of using

Using OpenSSL's MD5 library

 On the Linux machine, there is a command to calculate the MD5 value of the file, that is md5sum, if not, you need to install the RPM package: Coreutils. Now we can also easily compute the MD5 value of the file using the OpenSSL library. The main function to use is int Md5_init (Md5_ctx *c);int Md5_update (md5_ctx *c, const void *data, size_t len);int md5_final (unsigned char *md, md5_ctx *c); Before usi
