Open Source Unix Shell Cryptography Software

Duply is a shell front end for the duplicity backup tool https://duplicity.us . It simplifies the usage by implementing backup job profiles, batch commands and more. Secure backup to non-trusted file spaces made easy.

Encrypt or decrypt 12, 15, 18, 21 or 24 BIP39 codewords array (so-called "seed phrase") using exclusive OR (XOR)/Vernam cipher (a.k.a. One Time Pad). If not input by a user, an encryption key is automatically generated at random. Encryption with such a key preserves integrity of BIP-39 checksums of all keys (that's distinct while also compatible with SeedXOR implementation).

Active dictionary attack on WEP keys in WLAN networks.

Sign APK (or JAR) archives by OpenSSL, using standard private keys and certificates instead of keytool-managed keystores.

This tool will allow obfuscation of UNIX scripts listing an interpreter as the first line. It is most useful for distributing functionality in a commercial product or a high user volume environment where you wish to hide proprietary information.

AttackVector Linux is a new distribution for anonymized penetration and security. It is based on Kali and TAILS, which are both based on Debian. While Kali requires a modified kernel for network drivers to use injection and so forth, the Tor Project's TAILS is designed from the bottom up for encryption, and anonymity. Nmap can't UDP via Tor. The intention of AttackVector Linux is to provide the capability to anonymize attacks while warning the user when he or she takes actions that may compromize anonymity. The two projects have different design philosophies that can directly conflict with one another. In spite of this, the goal of AttackVector Linux is to integrate them complementarily into one OS.

Makes it easier to build a Linux system where the whole hard drive is encrypted (except for the MBR), and where the system must be booted from a USB memory stick which holds slightly customized boot code and the passphrase-protected keys.

Allows you to hide one file inside another

GNet Server - Network compression client/server software. Compresses data over slow networks to save on the cost of bandwidth. Server is developed for Unix and Windows platforms, The client will run on Windows based PCs.

GPODCS is a Certification Authority developed in the ESA Grid Processing On Demand (gpod.eo.esa.int) project. It offers a PKI infrastructure and GSI authorization management. GPODCS is portable, reliable, easy to install, configure and personalize.

Kojoney is an easy of use, secure, robust and powerfull Honeypot for the SSH Service written in Python. With the kojoney daemon are distributeds other tools such as kip2country (IP to Country) and kojreport, a tool to generate reports from the log fi

Multi-CA solution with support for complex certificate chains. Perfect for central management for several certificate authorities.

Naeon is a data encryption and sharding method designed to secure data in potentially untrusted off-site storage locations. It uses AES-256 encryption with a randomly generated passphrase, followed by obfuscation techniques to make the encrypted file unidentifiable. The data is then sharded into one private chunk containing the encryption key and part of the data, and multiple public chunks. Each chunk is renamed using its SHA-512 hash, and all chunks are timestamped equally. A filename conversion table is created to restore the concatenation order during a restore. The method aims to guarantee confidentiality, integrity, and availability of data, regardless of the trustworthiness of the chosen storage environment, while protecting against data breaches and unauthorized access. Threshold Key Sharing further enhances security and resilience by splitting the private key into parts requiring cooperation from multiple parties for reconstruction, thereby minimizing single points of failure.

OneKript is a Front-End for the program of disk encryption "on the flye" TrueCrypt, released under license GPL. It has been developed with the environment Kommander for KDE. At the moment is available the version 0.7.2.

Download code, Learn code, Share code. The Ongoing Object-oriented Perl Project. scripts, tutorials, modules, case studies, anything OOPerl --not excluding contributions of OO discipline in other programming languages.

PPDD-enabled RPMS for Red Hat Linux.

Project Naranja will uses Padlock Security of VIA EPIA mini-ITX motherboards in order to provide a toolkit to set up and use encrypted filesystems with Linux. NOTE: Files are now hosted at Google Code: http://code.google.com/p/naranja/

Qryptix consists of a PAM object and utilities for session- and key-management for encrypted home directories using the International Kernel (CryptoAPI) patches for Linux. It simplifies login/logout, mounting/unmounting, and key generation and changing.

partitioning backup recovery and all kind of boot loaders

Bash shell scripts to run an OpenSSL Certificate Authority (CA) and issue self-signed HTTPS server certificates (or cert signing requests) for intranets. Scripts: genrootca, genservercert, genusercert, revokecert, csv2usercerts, certificate-mailer.

SSPE: Simple Security Policy Editor is a simple distributed firewall with an central ascii administration. It uses two plain manually edited ascii-files and some other, static files for each of the target-machines to generate iptables.

Skein 512-512 hash algorithm implemented in Bash. Prepare to have your CPU pegged, and for simple hash calculations to take around 10 seconds. Hit the Home tab for details.

Live Security/Forensics Linux Distribution, built from scratch and packed full of tools useful for vulnerability analysis, penetration tests, and forensic analysis.

A small script to mount a TrueCrypt volume in one click.

UnityCA is a Certificate Authority "front end" based on the Community-Oriented CA (COCA) model, which was primarily developed for non-profit "free CAs." Organizational and end-user interfaces provide trusted web management of the installed CA (eg ElyCA).
