+// performs deterministic keygen based on the value specified in |seed| of
+// length |seed_len| bytes.
+//
+// If |out_pkey| and |seed| are set to NULL it is assumed that the caller is
+// doing a size check and the function will write the size of the required seed
+// in |seed_len| and return successfully.
+//
+// EVP_PKEY_keygen_deterministic performs a deterministic key generation
+// operation using the values from |ctx|, and the given |seed|. If |*out_pkey|
+// is non-NULL, it overwrites |*out_pkey| with the resulting key. Otherwise, it
+// sets |*out_pkey| to a newly-allocated |EVP_PKEY| containing the result.
+// It returns one on success or zero on error.
