Partners generate an Ed25519 key pair. The private key is used by the partner to sign requests. Once generated, send the base64-encoded public key to the Holdstation team so they can register it on your account. Keep the private key secret — never share it with anyone, including Holdstation.
To rotate your key later, see Upload Public Key.

Go Example

package main

import (
    "crypto/ed25519"
    "encoding/base64"
    "fmt"
)

func main() {
    // Generate Ed25519 key pair
    publicKey, privateKey, _ := ed25519.GenerateKey(nil)

    // Base64 encode for storage/transmission
    privateKeyB64 := base64.StdEncoding.EncodeToString(privateKey)
    publicKeyB64 := base64.StdEncoding.EncodeToString(publicKey)

    fmt.Println("Private Key (keep secret):", privateKeyB64)
    fmt.Println("Public Key (verify_key):", publicKeyB64)
}

Shell Script Example

openssl genpkey -algorithm ed25519 -out priv.pem
PRIVATE_KEY=$(cat priv.pem | openssl pkey -outform DER | tail -c 64 | base64)
VERIFY_KEY=$(openssl pkey -in priv.pem -pubout -outform DER | tail -c 32 | base64)
echo "Private Key (keep secret): $PRIVATE_KEY"
echo "Public Key (verify_key): $VERIFY_KEY"
