* Correct sign comparison error with sk_X509_OBJECT_num
In some build configurations, sk_X509_OBJECT_num (from BoringSSL) returns a size_t. Comparing this directly against a signed int loop counter triggers -Werror,-Wsign-compare.
Instead, move the count into a local int variable so the compiler uses implicit conversion to ensure type consistency during the loop comparison.
