See L<EC_GROUP_copy(3)> +for a description of point_conversion_form. + +When reading a private key encoded without an associated public key (e.g. if +EC_PKEY_NO_PUBKEY has been used - see below), then d2i_ECPrivateKey() generates +the missing public key automatically. Private keys encoded without parameters +(e.g. if EC_PKEY_NO_PARAMETERS has been used - see below) cannot be loaded using +d2i_ECPrivateKey(). + +The functions EC_KEY_get_enc_flags() and EC_KEY_set_enc_flags() get and set the +value of the encoding flags for the B<key>. There are two encoding flags +currently defined - EC_PKEY_NO_PARAMETERS and EC_PKEY_NO_PUBKEY. These flags +define the behaviour of how the B<key> is converted into ASN1 in a call to +i2d_ECPrivateKey(). If EC_PKEY_NO_PARAMETERS is set then the public parameters for +the curve are not encoded along with the private key. If EC_PKEY_NO_PUBKEY is +set then the public key is not encoded along with the private key. + +=head1 RETURN VALUES + +EC_KEY_get_enc_flags() returns the value of the current encoding flags for the +EC_KEY. + +=head1 SEE ALSO + +L<crypto(7)>, L<EC_GROUP_new(3)>, +L<EC_GROUP_copy(3)>, L<EC_POINT_new(3)>, +L<EC_POINT_add(3)>, +L<EC_GFp_simple_method(3)>, +L<d2i_ECPKParameters(3)>, +L<d2i_ECPrivateKey(3)> + +=head1 COPYRIGHT + +Copyright 2015-2017 The OpenSSL Project Authors.
