  • Uses good security practices (CBC mode, key derivation)
  • Zero-configuration and application level cryptography
  • Broad platform support: works with C/C++, Obj-C, QT, Win32/.NET, Java, Python, Ruby, Linux, iPhone/iOS and Android
  • Algorithms provided by the peer reviewed OpenSSL crypto library.
