#### Description Certificate serial numbers can be large integers (> 2^64). Parse then as BIGNUM and store the string in pv; we cannot store as integer anymore. The original code handles 2^64 with a static buffer of 19. We upsize to 2^256 with a static buffer of 80.

May break configurations that try to extract the sn pv as an integer (does anyone actually do this?)
