txtorcon is a Twisted-based asynchronous Tor control protocol implementation. Twisted is an event-driven networking engine written in Python, and Tor is an onion-routing network designed to improve people’s privacy and security on the Internet. It includes unit-tests with 96%+ coverage, multiple examples, and documentation. There are abstractions to track Tor configuration and state (circuits, streams), launch private instances, support Hidden Service, and more.
CERTivity is a powerful multi-platform visual tool for creating, managing, and handling different key store types (such as JKS, JCEKS, PKCS12, the Bouncy Castle types BKS and UBER, and Windows Native), public, private and secret keys in different formats (PKCS, OpenSSL, RSA/DSA, etc.), certificates (version 1 and 3), and certificates chains. It allows you to import and export keys, key pairs and certificates, manage certificate extensions, extend the validity period for self-signed certificates, test certificates, obtain revocation status, convert from one key store type to another, and much more.
strongSwan is a complete IPsec implementation for the Linux, Android, Maemo, FreeBSD, and Mac OS X operating systems. It interoperates with with most other IPsec-based VPN products via the IKEv2 or IKEv1 key exchange protocols. The focus of the strongSwan project is on strong authentication mechanisms using X.509 public key certificates and optional secure storage of private keys on smartcards through a standardized PKCS#11 interface. A rich choice of modular plugins adds additional features like Trusted Network Connect or advanced cryptographical algorithms.
jEncrypt is a commandline file encryption archiver. Files are encrypted with the AES-CTR mode, which was recommended by the National Institute of Standards and Technology in 2001 (NIST SP 800-38A). AES-CTR mode only provides confidentiality. It requires a message authentication code such as CBC-MAC to ensure an encrypted message is not accidentally modified or maliciously tampered with, which jEncrypt currently does not provide.
Dump Truck for Mac allows you to securely store, sync, and share all your photos, files, and documents online and access them anywhere. It doesn't rely on third parties to store your data or use data deduplication to inspect your data. The authors own their own storage infrastructure and store three copies of each file using 256-bit encryption. Android, iOS, and Windows apps are also available.
FTimes is a system baselining and evidence collection tool. Its primary purpose is to gather and/or develop topographical information and attributes about specified directories and files in a manner conducive to intrusion and forensic analysis. It was designed to support the following initiatives: content integrity monitoring, incident response, intrusion analysis, and computer forensics.
Tor is a network of virtual tunnels that allows people and groups to improve their privacy and security on the Internet. It also enables software developers to create new communication tools with built-in privacy features. It provides the foundation for a range of applications that allow organizations and individuals to share information over public networks without compromising their privacy. Individuals can use it to keep remote Websites from tracking them and their family members. They can also use it to connect to resources such as news sites or instant messaging services that are blocked by their local Internet service providers (ISPs).
Dar is a shell command that makes backup of a directory tree and files. Its features include splitting archives over several files, DVD, CD, ZIP, or floppies, compression, full or differential backups, strong encryption, proper saving and restoration of hard links, extended attributes, file forks, Door inodes, and sparse files, remote backup using pipes and external commands (such as ssh), and rearrangement of the "slices" of an existing archive. It can run commands between slices, before and after saving some defined files or directories (for a proper database backup, for example), and quickly retrieve individual files from differential and full backups. Several external GUIs exist as alternatives to its CLI interface, like kdar, DarGUI, SaraB, etc.
