Hey there all!!!

I have generated an account using aptos-labs/go-lang sdk as such

[Go] Recovering Ed25519PrivateKey from Ed25519Account

It's a bit hard due to the levels of abstraction, but because you know the signer is a Ed25519PrivateKey you can cast it for now. Or even cast to CryptoMaterial which is supported also on most Signer.

There are types of accounts, that may not have CryptoMaterial applied, e.g. when Keyless is supported here, it would not be able to print the private key (because there isn't one)

As CryptoMaterial:

package main

import (
	"github.com/aptos-labs/aptos-go-sdk"
	"github.com/aptos-labs/aptos-go-sdk/crypto"
)

func main() {
  acc1, _ := aptos.NewEd25519Account()
  key := acc1.Signer.(crypto.CryptoMaterial)
  println(key.ToHex())
}

As Ed25519PrivateKey:

package main

import (
	"github.com/aptos-labs/aptos-go-sdk"
	"github.com/aptos-labs/aptos-go-sdk/crypto"
)

func main() {
  acc1, _ := aptos.NewEd25519Account()
  key := acc1.Signer.(*crypto.Ed25519PrivateKey)
  println(key.ToHex())
}
