You do not generate the key used by aes when you use ssh-keygen. Since aes is a symmetric cipher, its keys do not come in pairs. Both ends of the communication use the same key. The key generated by ssh-keygen uses public key cryptography for authentication. From the ssh-keygen manual. At the Challenge password prompt, press Enter. At the Optional company name prompt, press Enter. OpenSSL generates the private key and CSR files. If you typed the command in step 2 exactly as shown, the files are named server.key and server.csr. You can now send the text in the server.csr file to the signing authority to obtain your certificate.

An RSA key is a private key based on RSA algorithm, used for authentication and an symmetric key exchange during establishment of an SSL/TLS session.
The RSA private key in PEM format (the most common format for X.509 certificates, CSRs and cryptographic keys) can be generated from the command line using the openssl genpkey utility.
