What is Oversec?
Oversec is an innovative privacy tool designed to enhance security across all Android applications. It operates by constantly monitoring text on the screen, automatically detecting encrypted content and decrypting it in real-time. The decrypted text is displayed as an overlay directly over the encrypted text, ensuring that sensitive information is only visible when needed and never stored on the device.
For encryption, Oversec integrates seamlessly with any app by adding a button next to active input fields. Users can enter secret text, tap the button to encrypt it, and the encrypted data is inserted back into the field, ready to be sent through the underlying app without the app's knowledge. It supports strong encryption methods including symmetric encryption with ChaCha20 cipher and Poly1305 MAC using 256-bit keys, as well as PGP public key encryption powered by Openkeychain. Additionally, Oversec offers unique features like hiding encrypted data behind decoy text and encrypting photos without storing originals, making it a versatile solution for secure communication.
