    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

    Advanced Onion Router
    Advanced Onion Router is a portable client for the OR network and is intended to be an improved alternative for Tor+Vidalia+Privoxy bundle for Windows users. Some of the improvements include UNICODE paths, support for HTTP and HTTPS proxy protocols on the same Socks4/Socks5 port with HTTP header filtering that generates fake identity-dependent headers every time the identity is changed (proxy chains are also supported), support for NTLM proxies, a User Interface that makes Tor's options and actions more accessible, local banlist for forbidden addresses, private identity isolation, a point-and-click process interceptor that can redirect connections from programs that don't support proxies, also giving them fake information about the local system and support for .onion addresses. Also, it can estimate AS paths for all circuits and prevent AS path intersections, it can restrict circuits to be built using only nodes from different countries, can change circuit lengths and more.

    A pronounceable password generator plugin for KeePass. NOTE: This project has been discontinued. It hasn't been worth it to maintain the project for a while now, so no more updates will be made to the plugin. The algorithm this plugin uses is based off FIPS-181 which was withdrawn by NIST a while back. The proliferation of password managers that seamlessly run on multiple platforms (some of which are free) has also removed almost all advantages of using randomly generated pronounceable passwords. If you have a use case for this plugin, reconsider it. If you still think using randomly generated pronounceable passwords are worth it for your use case, reconsider it some more.

    This script is capable of cracking multiple hashes from a CSV-file like e.g. dumps from sqlmap. Over 17.000 md5-hashes in a CSV-file get cracked with a 14.300.000 lines wordlist in less then 1 min. Lines wich cant get cracked with the wordlist get stored in a .leftToCrack-File to further process with another Wordlist or the bruteforce-tool. In addition to the wordlist-cracker I created also a bruteforce-tool named CSVHashBrutforcer.

    Naeon

    Naeon

    The safest way to store private data in untrusted (cloud) environments

    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.

    AESEncryptor is a fast and simple utility to protect your files with the Advanced Encryptation Standard algorithm. It is safer than zip or rar files because a simple force-attack can reveal their password. A force-attack to an AES encriptation could delay millions of years. There are available the source code of the GUI, a CaptionProgressBar and the RijndaelCryptorProvider, the core of the application which can start a encriptation process in a simple code line. New Version released (v2.5): - Add English Language - Some Bug Fixes - Added some options - Added some encriptation parameters IMPORTANT CRITICAL UPDATE (V2.5.0.1)!!!!! Fixes an error occurred with the Auto Delete option activated NEW UPDATE (V2.5.0.2) Fixes an crash when the program start or decrypt a file. Thanks to a SourceForge user for report the error UPDATED RijndaelCryptoProvider with a serious bug fix. Also, has been updated v2.5.0.2 and v2.5.0.1 with this new library
