# 取得金鑰
<a name="getkeys"></a>

 AWS 付款密碼編譯金鑰代表單一單位的密碼編譯資料，只能用於此服務的密碼編譯操作。GetKeys API 接受 KeyIdentifier 做為輸入，並傳回金鑰中繼資料，包括屬性、狀態和時間戳記，但不傳回實際的密碼編譯金鑰材料。

**Example**  

```
$ aws payment-cryptography get-key --key-identifier arn:aws:payment-cryptography:us-east-2:111122223333:key/kwapwa6qaifllw2h
```

```
