openssl rand 32 -out keyfile: Encrypt the key file using openssl rsautl: Encrypt the data using openssl enc, using the generated key from step 1. Here's what I get when I try using OpenSSL > 1.1.0c : OpenSSL only supports ECDH (for key exchange) and ECDSA (for digital signatures) for elliptic curve keys, i.e. Both are in .pem format (each in its own file). Let's examine openssl_rsa.h file. It must be decrypted first. Once done, you will notice that the ENCRYPTED wording in the file has gone. This information is known as a Distinguised Name (DN).
