Encrypt a Realm - .NET SDK¶
Overview¶
You can encrypt your local realm to ensure data security. For more information, see Encryption - .NET SDK.
Note
The same encryption key must be supplied every time you obtain a Realm instance.
If you don't provide a key, or specify the wrong key, for an encrypted
Realm, you will get a
RealmFileAccessErrorException
when you call GetInstance.
Example¶
The following code demonstrates how to generate an encryption key and open an encrypted realm:
// Check if we already have a key stored in the platform's secure storage. // If we don't, generate a new one: var encryptionKey = new byte[64]; using var rng = new RNGCryptoServiceProvider(); rng.GetBytes(encryptionKey); // Store the key securely to be used next time we want to open the Realm. // Create configuration. var config = new RealmConfiguration { EncryptionKey = encryptionKey }; // Open or create a realm with the encryption key. var realm = Realm.GetInstance(config);
