init method
void
init()
Initializes the CryptoModule by generating and storing a new encryption key and initialization vector (IV) in SimpleSharedPref. It only runs once and is safe to be called on app startup.
Implementation
void init() {
try {
final key = Key.fromSecureRandom(32);
final iv = IV.fromSecureRandom(16);
if (!SimpleSharedPref().containsKey(_obfuscatedKey)) {
SimpleSharedPref().preferences?.setString(_obfuscatedKey, key.base64);
SimpleSharedPref().preferences?.setString(_obfuscatedIV, iv.base64);
}
} catch (e) {
print('Initialization error: $e');
}
}
