sKasten at Mac App Store analyse

sKasten (Secure Box) is an cryptographic application based on AES-256 and RSA-2048 encryption algorithms. It simply encrypts and decrypts a file.

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 the encrypted file will be packed together as one package.
4. Use the appropriate RSA private key to decrypt the package.

Features :
1. Cross-Platform (Windows, iOS, OSX, Android) compatible.
2. AES-256 and RSA-2048 encryption/decryption.
3. File based encryption/decryption.
4. Support One to One and One to Many communication.
5. Can use RSA private key for both encryption and decryption.
6. Use RSA public key for encryption only.
7. Limited to intellectual property and copyright protection.
