Open Source Server Operating Systems Cryptography Software

WinSCP is a popular free file manager for Windows supporting SFTP, FTP, FTPS, SCP, S3, WebDAV and local-to-local file transfers. A powerful tool to enhance your productivity with a user-friendly interface and automation options like .NET assembly or batch file scripting. Use WinSCP also for file editing, directory synchronization and site management. WinSCP is open-source and well documented. It is available in English and many other languages.

FileVerifier++ is a Windows utility for calculating hashes using a number of algorithms including CRC32, MD5, SHA-1, SHA-256/224/384/512, WHIRLPOOL, and RIPEMD-128/160/256/320. Supported hash file formats include MD5SUM .MD5, SFV, BSD CKSUM, and others.

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 The algorithm this plugin uses is based off FIPS-181 which was withdrawn by NIST a while back.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.

The JWA library aims to provide a conversion from C to Delphi of as many headers as possible from the PSDK etc. The JWSCL (security library) is an advanced object-oriented framework for programming with the Windows security features (ACL, Tokens, etc.)

WebLocker is a free software that allows you to block annoying ads, block domains known to spread malware, block adult websites (Pornography), block social networks, block online gambling, stop DNS leaking and more features. Available for Windows: XP, 7, 8, 8.1 and 10. We hope you enjoy using WebLocker! TheYousSoft Team

NewPKI is a PKI based on the OpenSSL low-level API, all the datas are handled through a database, which provides a much more flexible PKI than with OpenSSL, such as seeking a certificate with a search engine.

psyBNC is an easy-to-use, multi-user, permanent IRC-Bouncer with many features. Some of its features include symmetric ciphering of talk and connections (Blowfish and IDEA) It compiles on Linux, FreeBSD, SunOs and Solaris.

Certificate-helper is a utility desktop application written in Java designed and created to assist (mainly developers) in creating and viewing keystores and digital certificates. This is done via a user interfaces implemented in Swing.

dk-milter consists of two parts: A milter-based application (dk-filter) which plugs in to Sendmail to provide DomainKeys service, and a library (libdk) which can be used to build DomainKeys-compliant applications or MTAs. See the home page for details.

Another open sourced crypto library. Unlike Crypto++ and cryptix, we're language independent. We originate in 'C', add wrappers for C++ and Objective-C. When that works, we provide a JNI wrapper for Java. Following this, we seek out Python,

BlowfishVHDL - free fully synthesizable Blowfish encryption algorithm hardware implementation.

No-Name Instant Messenger is a secure (strong cryptography), cross platform communications program that supports existing IM networks (AIM, Yahoo, ICQ, etc.).

Seahorse is a Gnome front end for GnuPG. It is a tool for secure communications and data storage. Data encryption and digital signature creation can easily be performed through a GUI, and Key Management operations also can be performed.

Alist is a program that collects hardware and software information about systems and stores it in a database for users to browse and search via a Web interface. The program consists of three parts: a client portion that collects the information, a daemon

This program allows you to establish cryptographically secure and decentraliced conversations over untrusted telecommunication links and IRC networks.

Corporate Data Protection and Network Security is a IT project targeting policy-based and fully-automated data protection, encryption and transmission. We plan to create self-diagnostic risk-predict enterprise environment with artificial intelligence.

Set of perl scripts to analyse and check expiration of user certificates in Microsoft Windows Certification Authority. Output is in HTML with list of expiration state of latest user certificates. Expirated are marked. List can be sent by e-mail.

Derived from TrueCrypt 6.3 release, I added some command line options to "TrueCrypt Format.exe" to allow TrueCrypt volumes to be created without using the graphical user interface

A WordPad-like cryptography program. Includes AES, RC4, Skipjack, Twofish, Blowfish, CryptAPI, DES, Gost, XOR, and TEA.

CryptoPy is a pure python implmentation of cryptographic algorithms and applications. The algorithms are developed for readability more than speed. The collection now includes IEEE 802.11i specific algorithms that generated the test vectors for 802.11i.

The Cryptofon is designed to enable safe and secure communication trough a regular PSTN line. It supports narrowband connections (~2400 bit/s and lower).

Cryptology is a Windows shell application that enables users to easily protect their files. It incorporates military grade encryption (256 AES) and secure shredding into a simple user interface

OpenPGP Keyserver written in ASP.NET (C#) This keyserver is not designed to synchronise with other servers. Suitable for deployment within a windows based organisation where sharing keys with internet keyservers is not required/desirable.

This program hidden inside compressed files of images, then these files can be extracted as if it were a tablet.

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.
