### Infra DID API Configuration

```javascript
import InfraDID from 'infra-did-js'

const confBlockchainNetwork = {
  networkId: '01',
  registryContract: 'infradidregi',
  rpcEndpoint: 'https://api.testnet.infrablockchain.com',
  txfeePayerAccount: 'txfeepayeraa',
  txfeePayerPrivateKey: 'TXFEE_PAYER_PRIVATE_KEY'
}
const conf = {
  ...confBlockchainNetwork,
  did: `did:infra:01:PUB_K1_8PwG7of5B8p9Mpaw6XzeyYtSWJyeSXVtxZhPHQC5eZxZCkqiLU`,
  didOwnerPrivateKey: 'DID_OWNER_PRIVATE_KEY'
}
const didApi = new InfraDID(conf)
```

### Infra DID Creation

currently secp256k1 curve is supported

```javascript
const pubKeyDID = InfraDID.createPubKeyDIDsecp256k1(networkId)
console.log({ pubKeyDID })
```

```javascript
{
  pubKeyDID: {
    did: 'did:infra:01:PUB_K1_8KeFXUKBR9kctm3eafs2tgqK3XxcqsnHtRp2kjSdfDFSn3x4bK',
