I've been using this command to generate a password protected ECC keypair.
openssl ecparam -name prime256v1 -genkey -noout | openssl pkey -aes256
-passout pass:passwd -text > tmpecprivkey.pem
The output is a
-----BEGIN ENCRYPTED PRIVATE KEY-----
which I parsed using
PEM_read_PrivateKey(pemKeyFile, NULL, NULL, (void *)password);
*ecKey = EVP_PKEY_get1_EC_KEY(evpPkey);
privateKeyBn = EC_KEY_get0_private_key(ecKey);
Now I must send the PEM file to a crypto library that does not support
-----BEGIN ENCRYPTED PRIVATE KEY-----
It expects
-----BEGIN EC PRIVATE KEY-----
Its parser does accept a password.
Is there a way to generate that PEM file? I.e.
A password protected ECC keypair in -----BEGIN EC PRIVATE KEY----- format/
