Android Secure data with cryptography

# Create public and private key with keyStore.

# Get KeyPairGenerator instance by providing algo and provider (algo: RSA, provider: AndroidKeyStore)

# Create AlgorithmParameterSpec and initialize to KeyPairGenerator instance.

# Generate Key Pairs , kpGenerator.generateKeyPair();


# Signs the data using the key pair stored in the Android Key Store.

# Get KeyStore instance with provider (AndroidKeyStore)

# Load the key pair from the Android Key Store using alias

# Get Signature and init with private key.

# Sign the data, store the result as a Base64 encoded String.
