# crypt.hmac

> Raw Lua string key kullanarak Lua string byte degerleri uzerinde crypto library HMAC hesaplar ve Base64 digest dondurur.

<div className="real-function-page">
  ```lua theme={null}
  crypt.hmac(key: string, data: string, algorithm?: "sha256" | "sha1" | "sha224" | "sha384" | "sha512" | "md5"): string
  ```

  ## Argümanlar

  <ParamField path={"key"} type={"string"} required>
    HMAC key olarak kullanilan raw Lua string byte degerleri. key Base64-decode edilmez.
  </ParamField>

  <ParamField path={"data"} type={"string"} required>
    HMAC calculation icine aktarilan Lua string byte degerleri.
  </ParamField>

  <ParamField path={"algorithm"} type={"\"sha256\" | \"sha1\" | \"sha224\" | \"sha384\" | \"sha512\" | \"md5\""}>
    Case-sensitive HMAC algorithm adi. Varsayilan deger sha256.
  </ParamField>

  ## Dönüşler

  <ResponseField name={"digest"} type={"string"}>
    Line breaks olmayan Base64-encoded HMAC output.
  </ResponseField>

  ## Örnek

  Raw Lua string key ve data ile Base64 HMAC output hesapla.

  ```lua theme={null}
  local key = "shared secret"
  local data = "payload"
  local digest = crypt.hmac(key, data, "sha256")

  print(digest)
  ```
