=head1 DESCRIPTION
An EC_KEY represents a public key and, optionally, the associated private
-key. A new EC_KEY with no associated curve can be constructed by calling
-EC_KEY_new(). The reference count for the newly created EC_KEY is initially
-set to 1. A curve can be associated with the EC_KEY by calling
+key.
+A new EC_KEY with no associated curve can be constructed by calling
+EC_KEY_new_ex() and specifying the associated library context in B<ctx>
+(see L<OPENSSL_CTX(3)>).
+The B<ctx> parameter may be NULL in which case the default library context is
+used.
+The reference count for the newly created EC_KEY is initially
+set to 1.
+A curve can be associated with the EC_KEY by calling
EC_KEY_set_group().
+EC_KEY_new() is the same as EC_KEY_new_ex() except that the default library
+context is always used.
+
Alternatively a new EC_KEY can be constructed by calling
-EC_KEY_new_by_curve_name() and supplying the nid of the associated curve. See
-L<EC_GROUP_new(3)> for a description of curve names. This function simply
-wraps calls to EC_KEY_new() and EC_GROUP_new_by_curve_name().
+EC_KEY_new_by_curve_name_ex() and supplying the nid of the associated curve and
+the library context to be used B<ctx> (see L<OPENSSL_CTX(3)>).
+The B<ctx> parameter may be NULL in which case the default library context is
+used.
+See L<EC_GROUP_new(3)> for a description of curve names.
+This function simply wraps calls to EC_KEY_new_ex() and
+EC_GROUP_new_by_curve_name_ex().
+
+EC_KEY_new_by_curve_name() is the same as EC_KEY_new_by_curve_name_ex() except
+that the default library context is always used.
Calling EC_KEY_free() decrements the reference count for the EC_KEY object,
and if it has dropped to zero then frees the memory associated with it. If
EC_KEY_up_ref() increments the reference count associated with the EC_KEY
object.
+EC_KEY_get0_engine() returns a handle to the ENGINE that has been set for
+this EC_KEY object.
+
EC_KEY_generate_key() generates a new public and private key for the supplied
B<eckey> object. B<eckey> must have an EC_GROUP object associated with it
before calling this function. The private key is a random integer (0 < priv_key
=head1 RETURN VALUES
-EC_KEY_new(), EC_KEY_new_by_curve_name() and EC_KEY_dup() return a pointer to
-the newly created EC_KEY object, or NULL on error.
+EC_KEY_new_ex(), EC_KEY_new(), EC_KEY_new_by_curve_name() and EC_KEY_dup()
+return a pointer to the newly created EC_KEY object, or NULL on error.
EC_KEY_get_flags() returns the flags associated with the EC_KEY object as an
integer.
EC_KEY_copy() returns a pointer to the destination key, or NULL on error.
+EC_KEY_get0_engine() returns a pointer to an ENGINE, or NULL if it wasn't set.
