PEM to EVP_PKEY

[Kory Hamzeh]

Hello,

So I have a PEM formatted file that contains an EC certificate and a private 
key. I need to load that PEM file and converted to an EVP_PKEY. The goal of 
this exercise is so that I can do an ECDH pairwise consistency test (SP 
800-56Ar3 Section 5.6.2.1.4) on the key pair by calling 
EVP_PKEY_pairwise_check(). I need some help in getting from the PEM file to an 
EVP_PKEY.

Thanks,
Kory
