Storing sensitive data like passwords and confidential information on your Android device unprotected is risky to say the least. Fortunately, the Secret Space Encryptor (SSE) app can take good care of your precious data. Using it, you can securely store passwords, encrypt text messages, and encrypt individual files and entire folders. The app offers several strong encryption algorithms, including 256-bit AES, 256-bit Serpent, and 256-bit Blowfish.
