The length returned by hexport_r has a few redundant characters. This appears as NULL characters at the end so seems harmless.
Remove the surplus counts in two places
totlen += strlen(ep->key) + 2; I'm guessing the +2 here is for = and sep char. But there is another totlen += 2; line that does that.
size = totletn + 1; Doesn't make sense and isn't justified with any comment.
