# Procurati le chiavi
Una chiave AWS di crittografia dei pagamenti rappresenta una singola unità di materiale crittografico e può essere utilizzata solo per operazioni crittografiche per questo servizio. L' GetKeys API accetta un KeyIdentifier input e restituisce i metadati chiave, inclusi attributi, stato e timestamp, ma non restituisce il materiale della chiave crittografica effettiva.
**Example**
```
$ aws payment-cryptography get-key --key-identifier arn:aws:payment-cryptography:us-east-2:111122223333:key/kwapwa6qaifllw2h
```
```

# key/certificate Associa il pubblico a una coppia di key pair
Get Public Key/Certificate restituisce la chiave pubblica indicata da`KeyArn`. Può trattarsi della parte di chiave pubblica di una coppia di chiavi generata su AWS Payment Cryptography o di una chiave pubblica importata in precedenza. Il caso d'uso più comune consiste nel fornire la chiave pubblica a un servizio esterno che crittograferà i dati. Tali dati possono quindi essere trasferiti a un'applicazione che sfrutta la crittografia dei AWS pagamenti e i dati possono essere decrittografati utilizzando la chiave privata protetta all'interno di Payment Cryptography. AWS
Il servizio restituisce le chiavi pubbliche come certificato pubblico. Il risultato dell'API contiene la CA e il certificato a chiave pubblica. Entrambi gli elementi di dati sono codificati in base 64.
**Nota**
Il certificato pubblico restituito è destinato a essere di breve durata e non è destinato a essere idempotente. È possibile ricevere un certificato diverso per ogni chiamata API, anche se la chiave pubblica stessa rimane invariata.
**Example**
```
$ aws payment-cryptography get-public-key-certificate --key-identifier arn:aws:payment-cryptography:us-east-2:111122223333:key/nsq2i3mbg6sn775f
