Current vers. w/ McEliece Algorithm. GoldBug has been 2013 - 2023 ten years just another Graphical User Interface of the Spot-On Encryption Suite. Main GUI features: Minimal & colorful Interface with Tabs in the East. Microsoft & Qt MinGW deprecated Win32 & for Compiling: ● https://sourceforge.net/p/goldbug/wiki/compiling As Spot-On implemented the minimal GB-concept & Nuvola Icons, GoldBug has now been fully integrated into Spot-On Win64: Just choose Tabs at East & Mini-View in Options - w/ Nuvola Icons of course!

This project is a C++ library which allows incorporating DKIM into an existing MTA or other application. It provides full support for signing, verifying, and SSP. It is compliant with RFC 4871.

NOTE: dkim-milter has been replaced by OpenDKIM, available at http://opendkim.org/ dkim-milter consists of two parts: A milter-based application (dkim-filter) which plugs in to Sendmail to provide DomainKeys Identified Mail service, and a library (libdkim) which can be used to build DKIM-compliant applications or MTAs.

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.

DKIM for JavaMail is a small JAR that can be easily implemented in existing Java projects using JavaMail for sending DKIM signed emails.

Mixmaster is an anonymous remailer. Remailers provide protection against traffic analysis and allow sending electronic mail anonymously or pseudonymously. Mixmaster consists of both client and server installations.

Codegroup is a Java application that will allow one to convert binary (or text) computer files in to 5 letter codegroups for transmission over email, landline telephones, radioteletype or Morse Code. Codegroup has internal error correction & limited cryptography capabilities.

siggen is a cool email signature generator for encrypted ansi c (confused), brainf*ck, ... signatures. Use it in combination with vi(m), emacs, mutt, pine, or what ever. (tested on Solaris, Linux and Windoze). Optimized only for geeks :-)

Mailcrypt is an Emacs Lisp package which provides a simple interface to public key cryptography with PGP [and now GnuPG!]. Mailcrypt makes strong cryptography a fully integrated part of your normal mail and news handling environment

PHP functions and classes to add a Domain Key Identified Mail (DKIM RFC 4871) signatures to emails sent by PHP. It is based on the openssl extensions of PHP. It can generate DKIM signature but cannot verify them. Developped and tested on PHP 4.0.

CommCA - A Community-driven Certificate Authority for distribution of free X.509 digital certificates for personal email and server use.

Commando is a military-grade secure communication system.

Cryptix OpenPGP is a library which implements the OpenPGP standard (RFC 2440) in Java.

Originally a software partnership between my best friend and myself, Diverse Developments seeks to write "useful stuff", of a very diverse nature... Current projects include a file encoder, and a double-entry accounts package.

Método y Sistema de voto electrónico vía e-mail utilizando par de claves asimétricas PGPl.

EntourageGPG provides powerful email encryption to Microsoft Entourage, using GPG as a backend.

Protect your company's email and browsing with your GoodCrypto private server. * Protects email metadata and resists traffic analysis * Automatic encryption, decryption, and key management * All private keys stay on *your* server * Users don't change their email or browser software * Blocks web malware * Runs on your private server * Completely decentralized

Haskell User-Submitted Libraries includes anything we can get our hands on and clean up for general use, as well as new libraries that would be useful to the general Haskell community. Submit your libs, or join the project to create needed libs!

ImpraStorage provided a private imap access to store large files. Each file stored on the server is split in severals random parts. Each part also contains random noise data (lenght depends on a crypt key) to ensure privacy and exclude easy merge without the corresponding key. An index of files stored is encrypt (with the symmetric-key algorithm Kirmah) and regularly updated. Once decrypt, it permit to perform search on the server and download each part. transfert process is transparent. Just vizualize locally the index of stored files and simply select files to download or upload. ImpraStorage automatically launch the parts to download, then merge parts in the appropriate way to rebuild the original file. Inversely, a file to upload is split (in several parts with addition of noise data), and ImpraStorage randomly upload each parts then update the index.

IDTrans is developing b2b technologies. The primary aspects of the project are secure transmission libraries, a key server, and a application to demonstrate the use of the libraries.

A standard API for accessing OpenPGP and S/MIME email in JavaMail.

An anonymous pseudonym email server, such as that which runs nym.alias.net.

OP/EN PKI is a PHP SSL public key infrastructure system to manage multiple Certificate Authorities, Certificates, Revocations lists and more. The standard formats for Apache, Email Applications, Web browsers and devices including x509, DER, and PKCS12.
