EC_KEY_GET_ENC_FLAGS(3)		    OpenSSL	       EC_KEY_GET_ENC_FLAGS(3)

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

SYNOPSIS
	#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);

DESCRIPTION
       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.

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