Encrypted Shared Preferences
Encrypted Shared Preferences is a feature in Android that provides a secure way to store sensitive data, such as user credentials or tokens. It uses encryption to keep data safe from unauthorized access.
Key Features:
AES Encryption: It uses AES encryption algorithms to ensure security.
Master Key: The MasterKeys.getOrCreate() method generates a strong encryption key to protect the shared preferences.
Ease of Use: You can use it like normal SharedPreferences, making it simple to implement.
Encrypted Shared Preferences provides an additional layer of security for sensitive information in your app. It helps prevent data leakage even if the device is compromised.
The Difference Between Shared Preferences & Encrypted Shared Preferences
The main difference between Shared Preferences and Encrypted Shared Preferences lies in the security of the data being stored. Here's a breakdown:
1. Data Security
Shared Preferences: Data stored in Shared Preferences is not encrypted by default. It is stored in plain text, which means if an attacker gains access to the device's storage, they can easily read the contents.
Encrypted Shared Preferences: Data is encrypted using AES encryption algorithms before it is stored. It ensures that even if someone gains access to the storage, they cannot read the data without the encryption key.
2. Use Cases
Shared Preferences: Suitable for storing non-sensitive data such as app settings, user preferences (e.g., theme mode), and other data that does not pose a security risk if exposed.
Encrypted Shared Preferences: Recommended for storing sensitive information such as user credentials, tokens, or any private data that requires a higher level of security.
