One thing that isn't entirely clear is whether the 20-octets limit implies a maximum integer value of 2^159 - 1 or of 2^160 - 1. Assuming the two's complement integer representation of DER, I would assume the former. For serial numbers, this is almost made explicit by the first paragraph of Appendix B ("almost" because it is not made explicit that the 20-octets limit refers to the DER encoding of the value), but there is no corresponding paragraph for CRL numbers, so one has to wonder whether there is some intended difference between the two. The sign bit having to be zero would also imply that you can't use just any SHA-1 hash value, besides the monotonicity requirement. Niklas
