encrypted the data and not get getting same data after decryption,in android code why you are not using algorithm

[brandtiwari007]

public void encrypt(String data, String key, String iv, String algorithm, Promise promise) {
try {
String result = encrypt(data, key, iv);
promise.resolve(result);
} catch (Exception e) {
promise.reject("-1", e.getMessage());
}
}
line 58-64 in java encrypt method
why are taking algorithm field from react-native side but not using it why?
