Hi Matt, I use: $ openssl version OpenSSL 1.0.1e-fips 11 Feb 2013
I was able to successfully parse your attached private key. I've attached my smallest prime, binary and kolbitz curve key pairs. As I said the prime curve parses correct with the openssl command line tool but not the binary curve keys.

What version of openssl are you using? Please see attached PEM file. Are you able to read that with openssl ec? Please send me a sample PEM that you are having difficulty with and I will see if I can read it. Matt
