nostr:npub1x0r5gflnk2mn6h3c70nvnywpy2j46gzqwg6k7uw6fxswyz0md9qqnhshtn
Got an LLM to write the code. Need to do a few edits to read the private key from a file, and syslogs will be files too?
Discussion
package main
import (
"fmt"
"github.com/nbd-wtf/go-nostr"
)
func main() {
// Generate a new private key
sk, err := nostr.GeneratePrivateKey()
if err!= nil {
fmt.Println("Error generating private key:", err)
return
}
// Derive the public key from the private key
pk, err := nostr.DerivePublicKey(sk)
if err!= nil {
fmt.Println("Error deriving public key:", err)
return
}
// Encode the private key into NIP-19 format
nsec, err := nostr.EncodePrivateKey(sk)
if err!= nil {
fmt.Println("Error encoding private key:", err)
return
}
// Encode the public key into NIP-19 format
npub, err := nostr.EncodePublicKey(pk)
if err!= nil {
fmt.Println("Error encoding public key:", err)
return
}
// Create a new event to represent the DM
event := &nostr.Event{
Type: "dm",
Payload: map[string]interface{}{
"recipient": npub,
"content": "Hello, world!",
},
Timestamp: nostr.Now(),
Signature: sk.Sign([]byte(fmt.Sprintf("%s %s", nsec, npub))),
}
// Publish the event to a relay
relayURL := "wss://your-relay-url-here"
err = nostr.Publish(event, relayURL)
if err!= nil {
fmt.Println("Error publishing event:", err)
return
}
fmt.Println("Direct message sent successfully!")
}
It will be stdin or file.
Stdin will be a line at a time? I can throw in a readline loop.
One giant string sent to stdin
package main
import (
"fmt"
"github.com/nbd-wtf/go-nostr"
"io/ioutil"
"log"
)
func main() {
// Generate a new private key
sk = "private key"
// Derive the public key from the private key
pk, _ := nostr.DerivePublicKey(sk)
// Encode the private key into NIP-19 format
nsec, _ := nostr.EncodePrivateKey(sk)
// Encode the public key into NIP-19 format
npub, _ := nostr.EncodePublicKey(pk)
filePath := "path/to/your/file.txt"
// Read the file into a byte slice
content, err := ioutil.ReadFile(filePath)
if err!= nil {
log.Fatalf("Failed to read file: %v", err)
}
// Convert the byte slice to a string
dmcontent := string(content)
// Create a new event to represent the DM
event := &nostr.Event{
Type: "dm",
Payload: map[string]interface{}{
"recipient": npub,
"content": dmcontent,
},
Timestamp: nostr.Now(),
Signature: sk.Sign([]byte(fmt.Sprintf("%s %s", nsec, npub))),
}
// Publish the event to a relay
relayURL := "wss://your-relay-url-here"
err = nostr.Publish(event, relayURL)
if err!= nil {
fmt.Println("Error publishing event:", err)
return
}
fmt.Println("Direct message sent successfully!")
}
Fixed a few bugs that the AI made. Replace the private key, file, and relay vars with your stuff, compile with "go build", and it should work
TY . Will try now. I am on a mini family vacation
No rush. Enjoy.
If it doesn't compile, ask the AI to fix it. Probably about err :=
how do you compile it? I checked out that GO repo, put a file called logger.go with your code
You got the compiler installed?
Yes
Make a folder like /home/verita84/go/src/nostrlogger then run "go mod init" inside. Then "go build logger.go". It may ask to run go get
If all is well, it should create a binary file named logger which you can put in your bin folder

Oops. Change to sk :=
:= is declaration, = is just assignment
That solved that error.

Did you run
go get github.com/nbd-wtf/go-nostr
?
Yes
undefined: nostr.DerivePublicKey
nostr is never defined anywhere
import ... go-nostr should define it. 🤔
Let me try to compile it in termux
Looks like your nsec section shoud be like this?
pk, _ := nostr.GetPublicKey(sk)
nsec, _ := nip19.EncodePrivateKey(sk)
npub, _ := nip19.EncodePublicKey(pk)
Does this compile?
It moves on
Looks like the entite event section is wrong too. Nothing like the sample
Need to read the code for .Publish() to see how to construct the event struct for DM
It's KindEncryptedDirectMessage. This is the struct. nip4.go has encryption functions
ev := nostr.Event{
PubKey: pub,
CreatedAt: nostr.Now(),
Kind: KindEncryptedDirectMessage,
Tags: nil,
Content: need to encrypt this,
}
