Generate 256-bit Key Automatically

Automatically generate random 256-bit keys in the Manage Keys section.

Ideal for encrypting/decrypting without manually creating keys.

Share/Import Encryption Keys via QR

Share any key you’ve created so others can use the same encryption key.

Export your key by pressing it in the list and choosing “Export.”

Import a key using a QR code in “Import key via QR” under key management.

File Encryption/Decryption

Select files from your device.

Encrypt or decrypt them using the same algorithms.

The output file name is automatically labeled “.encrypted” or “.decrypted.”

Built-In Key Manager :key:

Add, delete, or generate random keys.

Import keys from QR codes or export them as QR codes too.

Keys are stored securely (using EncryptedSharedPreferences).

Share Encryption Flow

Quick and convenient for multi-app workflows.

Optional Accessibility Service :handshake:
