           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.
