       EC_KEY_get_enc_flags, EC_KEY_set_enc_flags - Get and set flags for encoding EC_KEY


        #include <openssl/ec.h>

        unsigned int EC_KEY_get_enc_flags(const EC_KEY *key);
        void EC_KEY_set_enc_flags(EC_KEY *eckey, unsigned int flags);


       The format of the external representation of the public key written by i2d_ECPrivateKey()
       (such as whether it is stored in a compressed form or not) is described by the
       point_conversion_form. See 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

       The functions EC_KEY_get_enc_flags() and EC_KEY_set_enc_flags() get and set the value of
       the encoding flags for the 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
       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.


       EC_KEY_get_enc_flags() returns the value of the current encoding flags for the EC_KEY.
