        int EVP_PKEY_set1_DH(EVP_PKEY *pkey,DH *key);

        DH *EVP_PKEY_get1_DH(EVP_PKEY *pkey);

        int EVP_PKEY_assign_DSA(EVP_PKEY *pkey,DSA *key);
        int EVP_PKEY_assign_DH(EVP_PKEY *pkey,DH *key);

        int EVP_PKEY_type(int type);

DESCRIPTION

       EVP_PKEY_set1_RSA(), EVP_PKEY_set1_DSA(), EVP_PKEY_set1_DH() and EVP_PKEY_set1_EC_KEY()
       set the key referenced by pkey to key.

       EVP_PKEY_get1_RSA(), EVP_PKEY_get1_DSA(), EVP_PKEY_get1_DH() and EVP_PKEY_get1_EC_KEY()
       return the referenced key in pkey or NULL if the key is not of the correct type.

       EVP_PKEY_assign_RSA() EVP_PKEY_assign_DSA(), EVP_PKEY_assign_DH() and
       EVP_PKEY_assign_EC_KEY() also set the referenced key to key however these use the supplied
       key internally and so key will be freed when the parent pkey is freed.

       EVP_PKEY_type() returns the type of key corresponding to the value type. The type of a key
       can be obtained with EVP_PKEY_type(pkey->type). The return value will be EVP_PKEY_RSA,
       EVP_PKEY_DSA, EVP_PKEY_DH or EVP_PKEY_EC for the corresponding key types or NID_undef if
       the key type is unassigned.

NOTES

       In accordance with the OpenSSL naming convention the key obtained from or assigned to the
       pkey using the 1 functions must be freed as well as pkey.

       EVP_PKEY_assign_RSA() EVP_PKEY_assign_DSA(), EVP_PKEY_assign_DH() EVP_PKEY_assign_EC_KEY()
       are implemented as macros.

RETURN VALUES

       EVP_PKEY_set1_RSA(), EVP_PKEY_set1_DSA(), EVP_PKEY_set1_DH() and EVP_PKEY_set1_EC_KEY()
       return 1 for success or 0 for failure.

       EVP_PKEY_get1_RSA(), EVP_PKEY_get1_DSA(), EVP_PKEY_get1_DH() and EVP_PKEY_get1_EC_KEY()
       return the referenced key or NULL if an error occurred.

       EVP_PKEY_assign_RSA() EVP_PKEY_assign_DSA(), EVP_PKEY_assign_DH() and
       EVP_PKEY_assign_EC_KEY() return 1 for success and 0 for failure.
