### Quorum / Ethereum node key pair generation
```

var quorumKeyGen = require('quorum-keygen');

let nodeKeyPair = quorumKeyGen.generateNodeKeys();

// OR generate public key from a private key in hex

let nodeKeyPair = quorumKeyGen.generateNodeKeys('77bd02ffa26e3fb8f324bda24ae588066f1873d95680104de5bc2db9e7b2e510');

```

Output :
