To Restore Identity: restoreIdentity

Restoring an Identity can be done using an identity backup and the secret used to create the identity.

Restore an Identity

In the SDK, an identity is restored using restoreIdentity() function. It restores the IdentityEntity from a privateKeyand encryptedIdentityDb (Encrypted Identity Database) associated with the identity. 

Future<PrivateIdentityEntity> restoreIdentity(
      {required String privateKey, required String blockchain, required String network, Map<int, String>? encryptedIdentityDbs});

{
   return _restoreIdentityUseCase.execute(
        param: RestoreIdentityParam(
      secret: secret,
      identityBackup: encryptedIdentityDb,
    ));
}
It returns an identity as a PrivateIdentityEntityand throws IdentityException if an error occurs.

privateKey of the identity is a key that is used to access the sensitive information of the identity. This key is also used for generating proofs by using the credentials associated with the identity.

blockchain is the name of the blockchain associated with the identity. In our case, it is Polygon.

network is the type of network (Mainnet or Testnet) associated with the identity.

The encryptedIdentityDbs stores all the sensitive information related to the identity. It is a database where all the information associated with an identity is stored and secured by the identity (credentials, state, etc.). This information is stored in the SDK database and is accessible only by an Identity. The encryptedIdentityDbs is passed as a map of key:value pair where key is profileNonce and value is its corresponding encryptedIdentityDb value.

In short, the role of restoreIdentity() is to restore an IdentityEntity for an Integrator and then store it on the SDK. It returns the PrivateIdentityEntity object to the integrator to be able to operate with the identity.

Note: profileNonce functionality would be a part of the next release of the Wallet SDK.
