+[source,C]
+----

+                                const char *hash_algo,

+
+引数:
+
+* _data_: the data to hash
+* _data_size_: number of bytes to hash in _data_
+* _hash_algo_: hash algorithm used by the key derivation function, see table
+  in function <<crypto_hash_algorithms,crypto_hash>>
+* _salt_: the salt
+* _salt_size_: number of bytes in _salt_
+* _iterations_: number of iterations
+* _hash_: pointer to the hash variable, which is used to store the resulting hash
+  (the buffer must be large enough, according to the algorithm, see table in
+  function <<crypto_hash_algorithms,crypto_hash>>)
+* _hash_size_: pointer to a variable used to store the size of the hash computed
+  (in bytes) (can be NULL)
