Low-Cost Safety Improvements for Horizontal Curves

WebI am currently renewing an SSL certificate, and I was considering switching to elliptic curves. Per Bernstein and Lange, I know that some curves should not be used but I'm having difficulties selecting the correct ones in OpenSSL: $ openssl ecparam -list_curves secp112r1 : SECG/WTLS curve over a 112 bit prime field secp112r2 : SECG curve over a ... WebAug 8, 2024 · Curves will be at least 500 ft. in length for a central angle of 5° and increase 100 ft. for each 1° decrease in the central angle. For anticipated posted speeds of 60 mph or less, the minimum length of a curve is about 15 times the anticipated posted speed (mph).
