File Locker uses AES-256 bit algorithm which gives a massive security. AES-256 bit encryption is one of the most powerful encryption of this planet.

Even with the most powerful super computer it will take (9.63x10^52 years) Billion years to break a key.

Which is more than the age of the whole universe(13.75 Billion Years).
Encryption is always time consuming process. This app uses multi-threading for faster Encryption and Decryption Method.
