FAQ about react-native-aes-gcm-crypto
What is react-native-aes-gcm-crypto?
It is a React Native module that provides AES-GCM encryption and decryption for both iOS and Android platforms, enabling secure data handling in mobile applications.
What is AES-GCM encryption?
AES-GCM (Advanced Encryption Standard – Galois/Counter Mode) is a symmetric block cipher that combines AES encryption with Galois/Counter Mode (GCM) to provide both encryption and authentication.
What are the benefits of using AES-GCM encryption?
- Confidentiality: Encrypted data is kept secret and inaccessible to unauthorized parties.
- Integrity: GCM ensures that encrypted data remains unmodified and unaltered during transmission.
- Authentication: GCM verifies that the sender of the encrypted data is genuine and not an imposter.
What platforms are supported?
react-native-aes-gcm-crypto supports both iOS and Android platforms.
How do I install react-native-aes-gcm-crypto?
