# LiquidSecuritiesAuthorizer
This is an examples of external authorizer for Blockstream AMP.
___DON'T USE THIS CODE IN PRODUCTION___
- http.server is not ready for a production service
- we don't show how to add a tls certificate
- configurations are saved in the same file in plain text
- we don't have any api for gaids management
- we can not update rules during authorizer is running
- we allow skip signature check (only for debugging)
- we use error messages in json without specific codes
# How to use
Just clone this repository and call authorizer.py with python3.
```
python3 authorizer.py
```
The server will wait for connection and allow only POST with path `/issuerauthorizer`, other call will generate an error message
You can also specify a TCP port waiting for incoming messages (default: 5005).
```
python3 authorizer.py 80
```
# Configuration
## Liquid node configuration
Connect the authorizer to a Liquid Node in order to verify signature in received messages.
```
RPC_HOST = ''
RPC_PORT = ''
RPC_USER = ''
RPC_PASSWORD = ''
RPC_PASSPHRASE = ''
```
## Blockstream AMP platform signature
If you want check signature of received messages put `CHECK_SIGNATURE` to `True` and configure the `SIGNATURE_ADDRESS`.
```
CHECK_SIGNATURE = True
SIGNATURE_ADDRESS = ''
```
## Asset ID whitelist
This configuration allows to check the asset id for each transaction received, if you want enable it set `CHECK_ASSET_ID` to `True` and add asset id in hex to the `ASSET_ID` array.
```
CHECK_ASSET_ID = True
ASSET_ID = [
'',
'',
]
```
## Amount check
This settings allow filter transaction with little or big amount of token moved, if you want use set `CHECK_AMOUNT` to `True` and configure the min and max thresholds, transaction that move an amount outside this range will not be authorized.
```
CHECK_AMOUNT = True
MIN_AMOUNT = 0
MAX_AMOUNT = 1000000
```
## Whitelist and rules for inputs
This configuration allow you to set a list of account able to spend tokens, if you want use set `CHECK_GAID_IN` to `True` and insert in the `GAIDS_IN_WHITELIST` the authorized GAIDs.
```
CHECK_GAID_IN = True
GAIDS_IN_WHITELIST = [
'',
'',
'',
'',
'',
'',
]
```
## Whitelist and rules for outputs
This configuration allow you to set a list of account able to receive tokens, if you want use set `CHECK_GAID_OUT` to `True` and insert in the `GAIDS_OUT_WHITELIST` the authorized GAIDs.
If `ALLOWS_CHANGES` is set to `True` the GAIDs present in the transaction inputs will be temporary allowed to receive tokens, this is useful if we want allow a GAID to spend partially UTXO and receive back a change.
```
CHECK_GAID_OUT = True
GAIDS_OUT_WHITELIST = [
'',
'',
'',
'',
'',
'',
]
ALLOWS_CHANGES = True
```
