Technical question: how to sign a Tx when I only have the XRP 32-byte private key

[loupiote]

I just have the 32-byte value that is the private key for an XRP address (that has a balance).

Is there a way to create a wallet object that will allow me to do a "send" transaction from the XRP address corresponding to this private key?

I looked at the wallet API and could not find an obvious answer...

May I ask how you generated the public-private keys? If you used the xrpl.js (or) xrpl-py client library, then this task becomes easier.

The Wallet class accepts the public, private key pair in its constructor:

xrpl-py/xrpl/wallet/main.py

Line 43 in 9ceb380

def __init__(

Furthermore, you can specify seed, master_key_pair options in the constructor.

Please read the documentation of Wallet class and Cryptographic-key-pairs in XRPL to securely handle your private key material.

Thanks for your comments

May I ask how you generated the public-private keys?

It is really completely irrelevant. In that particular case, it was derived from a bip39 seed phrase that has been since lost.

So basically we have a 32-byte XRP private key, that's all we have.

The Wallet class accepts the public, private key pair in its constructor:

So I would have calculate the XRP public key (not an issue, as it can be calculated from the XRP private key) and modify the code. to create a "wallet" from the private key.

It would be really nice to have an option to create an XRP wallet from a 32-byte private key (without having to modify the code).

So maybe this could be seen as a feature request.

How are you generating the public-key from the private key? Can you point me to the documentation which details this process?

This issue hasn't been faced by many users. Unfortunately, we cannot prioritize it in the near future. However, if you submit a PR, we can review it.

I recommend looking at the raw signing functions at https://xrpl-py.readthedocs.io/en/stable/source/xrpl.core.keypairs.html
