From e5c39cdbd06f4ccb923681388453a135f09b6048 Mon Sep 17 00:00:00 2001 From: padreug Date: Wed, 15 Oct 2025 00:50:28 +0200 Subject: [PATCH] feat: integrate Nostr keypair generation with LNBits user accounts - Added Nostr private key storage to the accounts table via a new migration. - Updated Account model to include Nostr private key field. - Modified user creation process to automatically generate Nostr keypairs. - Introduced new API endpoints for retrieving Nostr public keys and user information including private keys. - Implemented tests to verify Nostr keypair generation and account model updates. --- lnbits/commands.py | 1 + lnbits/core/crud/users.py | 28 +++++- lnbits/core/helpers.py | 8 ++ lnbits/core/migrations_fork.py | 24 +++++ lnbits/core/models/users.py | 16 +++- lnbits/core/views/auth_api.py | 43 +++++++++ lnbits/core/views/user_api.py | 58 ++++++++++-- misc-aio/NOSTR_INTEGRATION.md | 140 +++++++++++++++++++++++++++++ misc-aio/test_nostr_integration.py | 96 ++++++++++++++++++++ 9 files changed, 406 insertions(+), 8 deletions(-) create mode 100644 lnbits/core/migrations_fork.py create mode 100644 misc-aio/NOSTR_INTEGRATION.md create mode 100644 misc-aio/test_nostr_integration.py diff --git a/lnbits/commands.py b/lnbits/commands.py index 87c8ddff..e12a226f 100644 --- a/lnbits/commands.py +++ b/lnbits/commands.py @@ -297,6 +297,7 @@ async def create_user(username: str, password: str): account.hash_password(password) user = await create_user_account_no_ckeck(account) click.echo(f"User '{user.username}' created.
