Related, one sharp edge with SEC.1 is, the the private key has the same length as order of the curve. That means, for example, a secp160 private key is 21 bytes instead of 20 bytes. I've seen bug reports because of the difference. The private key length was supposed to change to order of base point in a future version of SEC, but I did not see the change in SEC-2. Also, I have a copy of x9.62 if you need something copied. I don't have a copy of P1363, though.
