The size of the thing you pop from the stack is whatever it was when
you put it in. If the popped object is a char*, it's very likely
strlen() is the way to get the length. If it's a different object,
there are probably other ways to figure out the size. However, with
the little information you give us, we can't tell you. What exactly
was placed in skCerts?
The fact that sk_pop() returns a char* is irrelevant. It's used as a
generic type, and should be cast to whatever the real type is.
