    An encryption tool for creating file archives

    CrococryptFile is a file encryption tool which creates encrypted archives of files and folders. The encryption features of CrococryptFile can be compared to a ZIP utility that uses ZIP's AES encryption. However, there are significant differences.

Examples: - Password-based encryption (following PBKDF2) with AES-256, Twofish, Serpent, ... - Public key encryption using GPG/OpenPGP, Windows Keystore/CAPI with RSA/X.509 certificates - Cloaked (headerless) Password-based Encryption (AES-Twofish-256 cascaded) - ...

    SecuXabber

    SecuXabber

    A secure Jabber-client for Android using strong encryption

    SecuXabber is a secure Jabber-client for Android that bases on Xabber and uses a strong, asymmetric enryption that works on top of the XMPP protocol. A key pair is generated on application start-up. Users can send their public key to other SecuXabber users via Bluetooth. This ensures the origin of the public key because people do a face-to-face check during key exchange. After the keys are imported by both users, all communication between them is done fully encrpyted using a strong 4096 bit end-to-end encryption.
