What I did
Replace
memset()bymemset_s()Why I did it
memset()is an insecure function that can cause buffer overflow.memset()may not be called by the compiler. Due to compiler optimization: an optimizing compiler, which identifies and removes the function that overwrites the contents as a dead store because the memory is not used subsequently. If sensitive data is in memory, it's dangerous if compiler optimization happens.Ref:
