+     the EVP_PKEY_ECDH_KDF_X9_62 KDF type and ECDH_KDF_X9_62(). The old names

      if its length exceeds 4096 bytes. The limit has been raised to a buffer size

+paramgen type must have been set to x9.42.
 
 The EVP_PKEY_CTX_set_dh_paramgen_generator() macro sets DH generator to B<gen>

+The EVP_PKEY_CTX_set_dh_paramgen_type() macro sets the key type for DH

 1 the shared secret is padded with zeroes up to the size of the DH prime B<p>.
 If B<pad> is zero (the default) then no padding is performed.
 
 EVP_PKEY_CTX_set_dh_nid() sets the DH parameters to values corresponding to

+2.1, 2.2 and 2.3. or 0 to clear the stored value. This macro can be called

+
+Note that all of the following functions require that the B<ctx> parameter has
+a private key type of B<EVP_PKEY_DHX>. When using key derivation, the output of
+EVP_PKEY_derive() is the output of the KDF instead of the DH shared secret.
+The KDF output is typically used as a Key Encryption Key (KEK) that in turn
+encrypts a Content Encryption Key (CEK).
+
+The EVP_PKEY_CTX_set_dh_kdf_type() macro sets the key derivation function type
+to B<kdf> for DH key derivation. Possible values are B<EVP_PKEY_DH_KDF_NONE>
+and B<EVP_PKEY_DH_KDF_X9_42> which uses the key derivation specified in RFC2631
+(based on the keying algorithm described in X9.42). When using key derivation,
+the B<kdf_oid>, B<kdf_md> and B<kdf_outlen> parameters must also be specified.
+
+The EVP_PKEY_CTX_get_dh_kdf_type() macro gets the key derivation function type
+for B<ctx> used for DH key derivation. Possible values are B<EVP_PKEY_DH_KDF_NONE>
+and B<EVP_PKEY_DH_KDF_X9_42>.
+
+The EVP_PKEY_CTX_set0_dh_kdf_oid() macro sets the key derivation function
+object identifier to B<oid> for DH key derivation. This OID should identify
+the algorithm to be used with the Content Encryption Key.
+The library takes ownership of the object identifier so the caller should not
+free the original memory pointed to by B<oid>.
+
+The EVP_PKEY_CTX_get0_dh_kdf_oid() macro gets the key derivation function oid
+for B<ctx> used for DH key derivation. The resulting pointer is owned by the
+library and should not be freed by the caller.
+
+The EVP_PKEY_CTX_set_dh_kdf_md() macro sets the key derivation function

+that this digest should be SHA1 but OpenSSL tolerates other digests.
+
+The EVP_PKEY_CTX_get_dh_kdf_md() macro gets the key derivation function

+output length to B<len> for DH key derivation.
+
+The EVP_PKEY_CTX_get_dh_kdf_outlen() macro gets the key derivation function
+output length for B<ctx> used for DH key derivation.
+
+The EVP_PKEY_CTX_set0_dh_kdf_ukm() macro sets the user key material to
+B<ukm> and its length to B<len> for DH key derivation. This parameter is optional
+and corresponds to the partyAInfo field in RFC2631 terms. The specification
+requires that it is 512 bits long but this is not enforced by OpenSSL.
+The library takes ownership of the user key material so the caller should not
+free the original memory pointed to by B<ukm>.
