Methods
get(options: { key: string }): Promise<{ value: string }>
Note if item with specified key does not exist, throws an Error
set(options: { key: string; value: string }): Promise<{ value: boolean }>
Note return true in case of success otherwise throws an error
remove(options: { key: string }): Promise<{ value: boolean }>
Note return true in case of success otherwise throws an error
keys(): Promise<{ value: string[] }>
clear(): Promise<{ value: boolean }>
Note return true in case of success otherwise throws an error
getPlatform(): Promise<{ value: string }>
Note return returns which implementation is used - one of 'web', 'ios' or 'android'
Example
const key = 'username';
const value = 'hellokitty2';
SecureStoragePlugin.set({ key, value }).then(success => console.log(success));
const key = 'username';
SecureStoragePlugin.get({ key })
.then(value => {
console.log(value);
})
.catch(error => {
console.log('Item with specified key does not exist.');
});
async getUsername(key: string) {
return await SecureStoragePlugin.get({ key });
}
Platform specific information
iOS
This plugin uses SwiftKeychainWrapper under the hood for iOS.
Warning Up to version v0.4.0 there was standard keychain used. Since v0.5.0 there is separate keychain wrapper, so keys() method returns only keys set in v0.5.0 or higher version.
Android
On Android it is implemented by AndroidKeyStore and SharedPreferences. Source: Apriorit
Warning For Android API < 18 values are stored as simple base64 encoded strings.
Web
There is no secure storage in browser (not because it is not implemented by this plugin, but it does not exist at all). Values are stored in LocalStorage, but they are at least base64 encoded. Plugin adds 'capsec' prefix to keys to avoid conflicts with other data stored in LocalStorage.
