Hi,
Today i got security alert for my application. But why they send security alert?
In this alert, they found Unsafe Cryptographic Encryption , I using 32 bit encrypted key for storing user id into tinyDB without using Cryptographic component.
I attach image and link below
And i didn’t understand your logic about storing imei you get anytime if you want to know that users mobile is reset or imei change you simply store imei in tinydb without any encryption.
If want to encrypt just follow Kodular Challenge #4
Yes because there is many free apis which encrypt data but some of these store that details and some injects ransomeware which is encrypts all your data on your pc mobile and asks for money.
For more information kindly search
Ransomeware .cetori and many more
