Alias of #export
Serializes the DH parameters to a PEM-encoding.
Note that any existing per-session public/private keys will not get encoded, just the Diffie-Hellman parameters will be encoded.
PEM-encoded parameters will look like:
-----BEGIN DH PARAMETERS----- [...] -----END DH PARAMETERS-----
See also public_to_pem (X.509 SubjectPublicKeyInfo) and private_to_pem (PKCS #8 PrivateKeyInfo or EncryptedPrivateKeyInfo) for serialization with the private or public key components.
