<h4>NOTE: To use key pairs generated by OpenSSL</h4>
When you want to use a key pair which generated by OpenSSL, please
follow the instructions:
<blockquote><pre>
# generate secp256r1 curve EC key pair
% openssl ecparam -genkey -name secp256r1 -out k.pem
# print private key and public key
% openssl ec -in k.pem -nout -text
Private-Key: (256 bit)

</pre></blockquote>
Please delete colons ':' and new lines for the private key and the public key
and fill "EC private key (hex)" and "EC public key (hex)" in above form and
choose proper curve name,
then you can use them for signing and verification.
