    DAR - Disk ARchive

    DAR - Disk ARchive

    For full, incremental, compressed and encrypted backups or archives

    DAR is a command-line backup and archiving tool that uses selective compression (not compressing already compressed files), strong encryption, may split an archive in different files of given size and provides on-fly hashing, supports differential backup with or without binary delta, ftp and sftp protocols to remote cloud storage Archive internal's catalog, allows very quick restoration even a single file from a huge, eventually sliced, compressed, encrypted archive eventually located on a remote cloud storage, by only reading/fetching the necessary data to perform the operation. Dar saves *all* UNIX inode types, takes care of hard links, sparse files as well as Extended Attributes (MacOS X file forks, Linux ACL, SELinux tags, user attributes) and some Filesystem Specific Attributes (Linux ext2/3/4, Mac OS X HFS+) more details at: http://dar.linux.free.fr/doc/Features.html

    360-FAAR Analyze FW1 Cisco Netscreen Policy Offline Using Config/Logs

    360-FAAR (Firewall Analysis Audit and Repair) is an offline, command line, firewall policy manipulation tool to filter, compare to logs, merge, translate and output firewall commands for new policies, in Checkpoint dbedit, Cisco ASA or ScreenOS commands, and its one file! Read Policy and Logs for: Checkpoint FW1 (in odumper.csv / logexport format), Netscreen ScreenOS (in get config / syslog format), Cisco ASA (show run / syslog format), 360-FAAR compares firewall policies and uses CIDR and text filters to split rulebases / policies into target sections and identify connectivity for further analysis. 360-FAAR supports, policy to log association, object translation, rulebase reordering and simplification, rule moves and duplicate matching automatically. Allowing you to move rules to where you need them. Build new rulebases from scratch with a single 'any' rule and log files, with the 'res' and 'name' options. Switch into DROPS mode to analyse drop log entries.

    Bigram Table Generator

    Bigram Table Generator

    A program to generate random reciprocal bigram tables

    A command-line program to encrypt/decrypt a message using a random reciprocal bigram table and write a bigram table to a text file. Executing the program without any command-line arguments starts bigram in message encryption/decryption mode. The program prompts for a password or passphrase and a message to encrypt/ decrypt. After the message is entered the ciphertext is displayed. Executing the program with command-line arguments causes bigram to generate a random bigram table to print to screen or save to disk depending on whether the -f filename argument was given. If the -p passphrase argument is given a specific table is generated and is repeatable each time the same passphrase is given. This program was written to supplement the Enigma Simulator by Dirk Rijmenants. http://users.telenet.be/d.rijmenants/en/enigmasim.htm Enigma message procedures: http://users.telenet.be/d.rijmenants/en/enigmaproc.htm

    Cyberbit

    Cyberbit

    Visual Cryptography and Bit-Plane Complexity Segmentation in Python

    Hide secret messages in your pictures! Cyberbit lets you transmit a secret message to an intended person in a new manner. The secret message is an 1-bit deep black & white image. The message can contain written text, a drawing, a secret code etc. Using Visual Cryptography the application splits the secret message into two "shadow images" called <<shares>>. Any of the two shares will be embedded into a "normal" image file called by tradition <<vessel>>. You can use a method of hand to send the two vessels to your correspondent. For instance you can post one vessel image on facebook. The other vessel image can be sent as an attachment of an e-mail. The vessel images can be 8-bit gray-level images or 24-bit deep true-color images. Anyone who can correctly spot the two vessels and knows the dimensions of the image containing the secret message will be able to decrypt the secret message using the Cyberbit application.
