# OCI SDK

## Key Creation

Below you find an example call to create a key in OCI Vault and associate it with a wallet managed by the Wallet API.

The only thing that is important to note for the creation, that our system is only compatible with the following Key
types offered by the OCI Vault:

- RSA & ECDSA

Oracle KMS  key types [full list](https://docs.oracle.com/en-us/iaas/Content/KeyManagement/Tasks/dedicated_kms_pkcs_key_types.htm).

**Option: CURL**

**Endpoint:** `/keys/generate` | [API Reference](https://wallet.demo.walt.id/swagger/index.html#/Keys/post_wallet_api_wallet__wallet__keys_generate)

**Example Request**

```bash
curl -X 'POST' \
  'https://wallet.demo.walt.id/wallet-api/wallet/f01f8f55-d098-4c53-b47b-c97552829b39/keys/generate' \
  -H 'accept: */*' \
  -H 'Content-Type: application/json' \
  -d '{
  "backend": "oci",
  "config": {
    "vaultId": "ocid1.vault.oc1.eu-frankfurt-1.entbf645aabf2.abtheljshkb6dsuldqf324kitneb63vkz3dfd74dtqvkd5j2l2cxwyvmefeq",
    "compartmentId": "ocid1.compartment.oc1..aaaaaaaawirugoz35riiybcxsvf7bmelqsxo3sajaav5w3i2vqowcwqrllxa"
  },
  "keyType": "secp256r1"
}'
```

**Body**

```json
{
  "backend": "oci",
  "config": {
    "vaultId": "ocid1.vault.oc1.eu-frankfurt-1.entbf645aabf2.abtheljshkb6dsuldqf324kitneb63vkz3dfd74dtqvkd5j2l2cxwyvmefeq",
    "compartmentId": "ocid1.compartment.oc1..aaaaaaaawirugoz35riiybcxsvf7bmelqsxo3sajaav5w3i2vqowcwqrllxa"
  },
  "keyType": "secp256r1"
}
```

**Body Parameters**

- `backend`: _String_ - The location where the key is stored. In our case `oci` as we want to store it in oracle's vault.
- `config`
    - `vaultId`: _String_ - the OCID of the vault where the key should be stored.
    - `compartmentId`: _String_ - the OCID of the compartment where the vault is located.
- `keyType`: _String_ - the algorithm used to generate the key. For Vault only RSA and secp256r1 is possible.

**Example Response**

The API will respond with the ID of the key. This ID is the internal reference and can be used in operations such as DID
create or key delete.
