sKasten (Secure Box) is an cryptographic application based on AES-256 and RSA-2048 encryption algorithms. It simply encrypts and decrypts a file and is platforms (Windows, iOS, OSX, Android) compatible.
sKasten works like this :
1. Generate an AES-256 key to encrypt a file.
2. Use a RSA public key (self-generated or obtain from others) or private key to encrypt the AES-256 key.
3. The encrypted AES-256 key and encrypted data will be packed together as one package.
4. Use the appropriate RSA private key to decrypt the package.
