I fixed your bad code and i dont know how to get it to you so started this feel free to reply to it!

[jamieduk]

your code sucks i made it million times better i suggest you update your code with this

// sudo apt install golang
// go run main.go YOURSTRING 1
package main

import (
    "bytes"
    "crypto/ed25519"
    "crypto/sha512"
    "encoding/base32"

    "io/ioutil"
    "os"
    "regexp"
    "runtime"
    "strconv"
    "strings"
    "sync"

    "golang.org/x/crypto/sha3"
)

func generate(wg *sync.WaitGroup, re *regexp.Regexp) {

    for {

        publicKey, secretKey, err := ed25519.GenerateKey(nil)
        checkErr(err)

        onionAddress := encodePublicKey(publicKey)

        // If a matching address is found, save key and notify wait group
        if re.MatchString(onionAddress) == true {
            fmt.Println(onionAddress)
            save(onionAddress, publicKey, expandSecretKey(secretKey))
            wg.Done()
        }
    }
}

func expandSecretKey(secretKey ed25519.PrivateKey) [64]byte {

    hash := sha512.Sum512(secretKey[:32])
    hash[0] &= 248
    hash[31] &= 127
    hash[31] |= 64
    return hash

}

func encodePublicKey(publicKey ed25519.PublicKey) string {

    // checksum=H(".onion checksum" || pubkey || version)
    var checksumBytes bytes.Buffer
    checksumBytes.Write([]byte(".onion checksum"))
    checksumBytes.Write([]byte(publicKey))
    checksumBytes.Write([]byte{0x03})
    checksum := sha3.Sum256(checksumBytes.Bytes())

    // onion_address=base32(pubkey || checksum || version)
    var onionAddressBytes bytes.Buffer
    onionAddressBytes.Write([]byte(publicKey))
    onionAddressBytes.Write([]byte(checksum[:2]))
    onionAddressBytes.Write([]byte{0x03})
    onionAddress := base32.StdEncoding.EncodeToString(onionAddressBytes.Bytes())

    return strings.ToLower(onionAddress)

    checkErr(ioutil.WriteFile(onionAddress+"/hs_ed25519_secret_key", secretKeyFile, 0600))

    publicKeyFile := append([]byte("== ed25519v1-public: type0 ==\x00\x00\x00"), publicKey...)
    checkErr(ioutil.WriteFile(onionAddress+"/hs_ed25519_public_key", publicKeyFile, 0600))

    checkErr(ioutil.WriteFile(onionAddress+"/hostname", []byte(onionAddress+".onion\n"), 0600))
}

func checkErr(err error) {
    if err != nil {
        panic(err)
    }
}

func main() {

    // Set runtime to use all available CPUs.
    runtime.GOMAXPROCS(runtime.NumCPU())

    // Compile regex from first argument.
    re, _ := regexp.Compile("^" + os.Args[1])

    // Get the number of desired addreses from second argument.
    numAddresses, _ := strconv.Atoi(os.Args[2])

    // WaitGroup of size equal to desired number of addresses
    var wg sync.WaitGroup
    wg.Add(numAddresses)

    // For each CPU, run a generate goroutine
    for i := 0; i < runtime.NumCPU(); i++ {
        go generate(&wg, re)
    }

    // Exit after the desired number of addresses have been found.
    wg.Wait()

}

Alsao your readme should never point to a website thats dumb asf always put actual instructions its not fkin hard

sudo apt install -y golang

go run main.go YOURSTRING 1

Where Yourstring is your desired hostname start string And Where 1 is the number of found hostname matches to stop at!

[ManicDevs]

@jamieduk - I don't know what you are on about, because your code actually has errors too. lol

"Also" your spelling and grammar is poor. _ Alas, If you are saying where 1 is the number of found hostname that the match would stop on.

Enjoy, - So I see not how your code is any better.
