Here are Steps used to generate key and created buffer array with xxd:

generate pvt key:

openssl ecparam -name secp384r1   -genkey -noout -out ca-root.key

generate cert:
openssl req -new -x509 -key ca-root.key -out  ca-root..crt  -days 3650 -subj /CN=somecn.com/emailAddress=myemail.com

openssl x509 -in ca-root.crt  -outform DER | xxd -i

openssl ec -in ca-root.key -outform DER | xxd -i

I have tried creating EC certs and keys with curve secp384r1 & prime256v1 mbed M3 for embedded SSL.  I'm getting error while loading key as below. Can someone throw some light on it ?

-4 means invalid file. But doesn;t seems so as i have used same process for RSA and it does load key.

CyaSSL_CTX_use_PrivateKey_buffer(ctx, CAKey, sizeof(CAKey), SSL_FILETYPE_ASN1);

Thanks,
Amit

Did you get it working by any chance ? Can you share your settings.h for mbed on LCP1768?

Hi Chris,

Can you send resource use document to me as well ?

Thanks,
Amit
