41 | =head1 DESCRIPTION | ||
42 | |||
43 | An EC_KEY represents a public key and (optionally) an associated private key. A new EC_KEY (with no associated curve) can be constructed by calling EC_KEY_new. | ||
44 | 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 | ||
45 | EC_KEY_set_group. | ||
46 | |||
47 | Alternatively a new EC_KEY can be constructed by calling EC_KEY_new_by_curve_name and supplying the nid of the associated curve. Refer to L<EC_GROUP_new(3)|EC_GROUP_new(3)> for a description of curve names. This function simply wraps calls to EC_KEY_new and | ||
48 | EC_GROUP_new_by_curve_name. | ||
49 | |||
50 | 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 | ||
51 | with it. | ||
52 | |||
53 | EC_KEY_copy copies the contents of the EC_KEY in B<src> into B<dest>. | ||
54 | |||
55 | EC_KEY_dup creates a new EC_KEY object and copies B<ec_key> into it. | ||
56 | |||
57 | EC_KEY_up_ref increments the reference count associated with the EC_KEY object. | ||
58 | |||
59 | 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 | ||
60 | associated with it before calling this function. The private key is a random integer (0 < priv_key < order, where order is the order | ||
61 | of the EC_GROUP object). The public key is an EC_POINT on the curve calculated by multiplying the generator for the curve by the | ||
62 | private key. | ||
63 | |||
64 | EC_KEY_check_key performs various sanity checks on the EC_KEY object to confirm that it is valid. | ||
65 | |||
66 | EC_KEY_set_public_key_affine_coordinates sets the public key for B<key> based on its affine co-ordinates, i.e. it constructs an EC_POINT | ||
67 | object based on the supplied B<x> and B<y> values and sets the public key to be this EC_POINT. It will also performs certain sanity checks | ||
68 | on the key to confirm that it is valid. | ||
69 | |||
70 | The functions EC_KEY_get0_group, EC_KEY_set_group, EC_KEY_get0_private_key, EC_KEY_set_private_key, EC_KEY_get0_public_key, and EC_KEY_set_public_key get and set the EC_GROUP object, the private key and the EC_POINT public key for the B<key> respectively. | ||
71 | |||
72 | 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 | ||
73 | flags currently defined - EC_PKEY_NO_PARAMETERS and EC_PKEY_NO_PUBKEY. These flags define the behaviour of how the B<key> is | ||
74 | 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 | ||
75 | along with the private key. If EC_PKEY_NO_PUBKEY is set then the public key is not encoded along with the private key. | ||
76 | |||
77 | The functions EC_KEY_get_conv_form and EC_KEY_set_conv_form get and set the point_conversion_form for the B<key>. For a description | ||
78 | of point_conversion_forms please refer to L<EC_POINT_new(3)|EC_POINT_new(3)>. | ||
79 | |||
80 | EC_KEY_insert_key_method_data and EC_KEY_get_key_method_data enable the caller to associate arbitrary additional data specific to the | ||
81 | elliptic curve scheme being used with the EC_KEY object. This data is treated as a "black box" by the ec library. The data to be stored by EC_KEY_insert_key_method_data is provided in the B<data> parameter, which must have associated functions for duplicating, freeing and "clear_freeing" the data item. If a subsequent EC_KEY_get_key_method_data call is issued, the functions for duplicating, freeing and "clear_freeing" the data item must be provided again, and they must be the same as they were when the data item was inserted. | ||
82 | |||
83 | EC_KEY_set_flags sets the flags in the B<flags> parameter on the EC_KEY object. Any flags that are already set are left set. The currently defined standard flags are EC_FLAG_NON_FIPS_ALLOW and EC_FLAG_FIPS_CHECKED. In addition there is the flag EC_FLAG_COFACTOR_ECDH which is specific to ECDH and is defined in ecdh.h. EC_KEY_get_flags returns the current flags that are set for this EC_KEY. EC_KEY_clear_flags clears the flags indicated by the B<flags> parameter. All other flags are left in their existing state. | ||
84 | |||
85 | EC_KEY_set_asn1_flag sets the asn1_flag on the underlying EC_GROUP object (if set). Refer to L<EC_GROUP_copy(3)|EC_GROUP_copy(3)> for further information on the asn1_flag. | ||
86 | |||
87 | EC_KEY_precompute_mult stores multiples of the underlying EC_GROUP generator for faster point multiplication. See also L<EC_POINT_add(3)|EC_POINT_add(3)>. | ||
88 | |||
