Code Review

This pull request enhances the robustness of the OpenSSL certificate format verification by adding null pointer checks for the Subject Key Identifier (SKID) and Authority Key Identifier (AKID). The previous implementation could lead to a null pointer dereference and a potential crash if these optional extensions were not present in a certificate. The added checks correctly handle this case by verifying the pointers are not null before accessing their members. The change is correct and improves the stability of the code. I have no further comments.
