Export Key

---

Users can at any time request to "export" their keys into a private key.

Step 1 : Create Session

---

• Create TrioSession if you haven't already.

Step 2 : Perform Export

---

• Call trioSession.export() with the keyId which returns Result of Success with the exported private key as ByteArray or Failure with exception.

Example

---

Example.kt

// export reconstructs the raw private key of the key addressed by keyId.
// Treat the result like any private key — encrypt it at rest; bring it back
// under MPC later with import.
suspend fun exportPrivateKey(keyId: String, trioSession: TrioSession): ByteArray {
    return withContext(Dispatchers.IO) {
        trioSession.export(
            keyId = keyId
        ).getOrThrow()
    }
}

• keyId: Identifies the key to export; it is returned by keygen and addresses the client's keyshare in your storage.
