Objective: After receiving the constructed secp256k1 private key from plug-n-play module, how to store the private key securely and also do the same for ed25119 private key?

Solutions identified:

Android KeyStore: web3auth react-native sdk has mention in the code of using Android KeyStore https://github.com/Web3Auth/web3auth-react-native-sdk/blob/42c880471728e5b2dfc820f09575751019a77116/src/session/KeyStore.ts but no mention of the reference in the documentation or code example with all SDKs
iOS Keychain: I couldn’t find reference for the same for iOS keychain

Request:

Point me to the SDK example and reference in the Docs where for both Android and iOS equivalent key store and keychain.

Hey @mr.y

If you check the return in the PnP mobile SDKs, you’re returned both secp256k1 and ed25519 private keys in the login response. These both are dynamically reconstructed and returned back.

Next week, we’re launching session management in our PnP React Native SDK, which will help you implement this seemlessly without any problems. This feature has existed in our Android and iOS SDKs for a while now.
