    Tor Browser

    Tor Browser

    Browser for using Tor on Windows, Mac OS X or Linux

    Tor Browser enables you to use Tor on Windows, Mac OS X, or Linux without needing to install any software. Tor is a software that bounces your communications around a distributed network of relays run by volunteers. This effectively prevents anyone watching your Internet connection from learning what sites you visit; it prevents the sites you visit from learning your physical location; and allows you access to sites which are blocked. Tor Browser can run off a USB flash drive, comes with a pre-configured web browser to protect your anonymity, and is self-contained (portable).

    VeraCrypt

    VeraCrypt

    Open source disk encryption with strong security for the Paranoid

    VeraCrypt is a free disk encryption software brought to you by IDRIX (https://www.idrix.fr) and based on TrueCrypt 7.1a. It adds enhanced security to the algorithms used for system and partitions encryption making it immune to new developments in brute-force attacks. It also solves many vulnerabilities and security issues found in TrueCrypt. This enhanced security adds some delay ONLY to the opening of encrypted partitions without any performance impact to the application use phase. This is acceptable to the legitimate owner but it makes it much harder for an attacker to gain access to the encrypted data. All released files are PGP signed with key ID=0x680D16DE, available on key servers and downloadable at https://www.idrix.fr/VeraCrypt/VeraCrypt_PGP_public_key.asc VeraCrypt can mount TrueCrypt volumes. It also can convert them to VeraCrypt format. Documentation: https://www.veracrypt.fr/en/Documentation.html FAQ : https://www.veracrypt.fr/en/FAQ.html

    LOIC TCP/IP Stresser v1.1.0.1 By LifeOwner

    LOIC TCP/IP Stresser Tool History I was downloaded the original LOIC within version 1.0.8.0 and changed it to be better without changing the other functions which were worked nice. The grey skin i hope you like it! Reworked by LifeOwner. New Features Work • The UDPV2 work like charm with low builded connections you might get timeout in your internet connection might cause you're too slow. (I tested it with 25MB's Downstream/ 2MB's Upstream). • The status checker function will be slowly when the ip->port will be offline, so do not worry the program still running and working on it, just the timeout is bigger than usually to make sure it will works for slower connections. Have fun with it i hope you will like it! New build by LifeOwner 2016.
