eacc is a bash script that allows a group of people to share an encrypted, revision controlled file on a shared filesystem. Rather than store an encrypted file in RCS, eacc encrypts the RCS file and handles the decryption, check-out, check-in, and encryption steps automatically. The repository is encrypted using GPG's multi-recipient support, which allows each member of the group to use their own unique password. A typical use case would be to securely store sensitive information, such as password lists or account information, that is shared by a team.
Chrubix transforms your ARM-based Chromebook into a fully functional, more secure laptop. The OS is installed on a removable MultiMediaCard (MMC). You can choose between ArchLinux, Debian, Fedora, Kali, SuSE, and Ubuntu for the underlying OS. Chrubix supplies Guest Mode, full-disk encryption, a Windows XP lookalike mode, MAC address randomizing, a panic button, additional checksums, and a variety of important security-oriented software applications such as Freenet, I2P, Tor, GPG, and LEAP-Bitmask. In addition, Chrubix offers you the option to tweak the software so that it will run on no hardware but yours (MMC and laptop must match).
