How to get private key?

// WIF private key

In the code I have seen Work-In-Progress for fetching private key. Is it In progress?
or Is it completed?
Please let me know can I use this library code for following:

1. Crating and fetching private key?
2. Can I use the library code for Singapore based wallet app?
3. Can I buy bitcoin/ethereum in Singapore.
4. Can I use for transaction creation for cryptocurrency?

We do not currently have plans for exporting your private key. Tools exist to convert the BIP39 phrase to a private key if you require this.
