Broken links to secg.org

[DavidEGrayson]

In issue #10, @mcr pointed out that some of my links to secg.org are broken.

http://www.secg.org/collateral/sec1_final.pdf
This is supposed to go to a document called "SEC 1: Elliptic Curve Cryptography" dated 2000-09-20, with version number 1.0 and a SHA256 hash of abe38d818c470d3e5a57e991e2ae410cbe0608fd0f191ed8788d0401e7d6c616. There is a new document from the same domain with version number 2.0, but I have not read it carefully enough to know if all the broken links can be updated to it.

This is supposed to go to a document called "SEC 2: Recommended Elliptic Curve Domain Parameters" dated 2000-09-20, with version number 1.0 and a SHA256 hash of d1b16728ad83888fd656d16b99dc71bcd5541d42d848ffd0de7c62c19010d8c3. There is a new document with version number 2.0 from the same domain, but it is not a suitable replacement for version 1.0 because it removes several curves.

I'll go ahead and attach the original documents (that I seem to have downloaded on 2017-05-19) to this issue. Thanks for the free file storage, GitHub!
