EC_KEY_get_enc_flags(3)             OpenSSL            EC_KEY_get_enc_flags(3)

       EC_KEY_get_enc_flags, EC_KEY_set_enc_flags - Get and set flags for
       encoding EC_KEY structures

       libcrypto, -lcrypto

        #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 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 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.
