To set up a new alert system |
|||
---------------------------- |
|||
|
|||
Create a new alert key pair: |
|||
openssl ecparam -name secp256k1 -genkey -param_enc explicit -outform PEM -out data.pem |
|||
|
|||
Get the private key in hex: |
|||
openssl ec -in data.pem -outform DER | tail -c 279 | xxd -p -c 279 |
|||
|
|||
Get the public key in hex: |
|||
openssl ec -in data.pem -pubout -outform DER | tail -c 65 | xxd -p -c 65 |
|||
|
|||
Update the public keys found in chainparams.cpp. |
|||
|
|||
|
|||
To send an alert message |
|||
------------------------ |
|||
|
|||
Copy the private keys into alertkeys.h. |
|||
|
|||
Modify the alert parameters, id and message found in this file. |
|||
|
|||
Build and run with -sendalert or -printalert. |
|||
|
|||
./hushd -printtoconsole -sendalert |
|||
|
|||
One minute after starting up, the alert will be broadcast. It is then |
|||
flooded through the network until the nRelayUntil time, and will be |
|||
active until nExpiration OR the alert is cancelled. |
|||
|
|||
If you make a mistake, send another alert with nCancel set to cancel |
|||
the bad alert. |
