12  * DOC: DH Helper Functions
14  * To use DH with the KPP cipher API, the following data structure and
17  * To use DH with KPP, the following functions should be used to operate on
18  * a DH private key. The packet private key that can be set with
23  * struct dh - define a DH private key
25  * @key:	Private DH key
29  * @key_size:	Size of the private DH key
30  * @p_size:	Size of DH parameter P
31  * @q_size:	Size of DH parameter Q
32  * @g_size:	Size of DH generator G
34 struct dh {  struct
46  * crypto_dh_key_len() - Obtain the size of the private DH key
47  * @params:	private DH key
49  * This function returns the packet DH key size. A caller can use that
50  * with the provided DH private key reference to obtain the required
55 unsigned int crypto_dh_key_len(const struct dh *params);  argument
59  * @buf:	Buffer allocated by the caller to hold the packet DH
65  * The DH implementations operate on a packet representation of the private
70 int crypto_dh_encode_key(char *buf, unsigned int len, const struct dh *params);
77  *		unpacked DH private key.
84 int crypto_dh_decode_key(const char *buf, unsigned int len, struct dh *params);
