WARNING: THIS IS EXPERIMENTAL SOFTWARE. IT IS LIKELY TO CONTAIN BUGS.
If you have already installed Centry, please run
git pullto update to the latest version. The latest updates make it much more secure against replay attacks.
Centry is a panic button intended to protect users against Cold Boot Attacks, Direct Memory Access Attacks and other live system threats. Centry is most effective when deployed on systems with Full Disk Encryption and without a swap/page file. The panic function can be activated through the GUI or through a network request (through browser, smartphone, etc). Upon recieving the panic instruction, Centry will attempt to remove sensitive keys from memory, securily overwrite the RAM and then force a shutdown.
For significantly improved security install the
secure-deletepackage. On Ubuntu/Debian:
sudo apt-get install secure-delete
Then download and run Centry as root:
git clone https://github.com/0xPoly/Centry.git sudo python centry.py "password"
