Yes but "DER encoded public and private keys" doesn't mean much, since
it doesn't specify what structure is being DER encoded.

Specifically it can use PKCS#8 for private keys.
PKCS#1 for RSA private keys.
SubjectPublicKeyInfo for public keys.

Encrypted private keys using the default options but they can be
converted to PKCS#8.
