This is the final release of truecrypt (7.1a) ported to use wxGTK3 instead of 2.8. None of the underlying code has changed, instead the compile errors due to modern distros using and updated version of wxGTK have been resolved (for now).

IMPORTANT -- This is an old project that is no longer supported and should not be relied upon for serious applications. If your looking for encryption software, I suggest OpenSSL or GnuPG which are better equipped.

GPG-Crypter is a graphical front-end to GnuPG(GPG) using the GTK3 toolkit and GPGME library. It has been developed to provide an easy access to GPG encryption and decryption. It supports encryption and decryption of text entered into the program's input fields. It also supports file encryption and decryption.

This is an open source Java Card implementation of the ISO7816 and related PKI standards. An ISO7816 file system for storing PKI files according to the Part 15 of the ISO7816 specification [3]: private key directory, certificate directory, CA and user certificates, etc. Download all files, you can visit:

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.

Secret File is a free and easy to use encryption/decryption app that can encrypt nearly any kind of file format using passwords. Files can be stored as personal or sent over the internet as confidential as the data of files are securely encrypted at the binary level itself and can be decrypted at any time and anywhere. You can also use multi-level protection for more secureness.

This tool can create XAdES (XML) signatures based upon ETSI TS 101 903 v1.3.2 standard. It also includes handling of ITU-T X.509 certificates and RFC 3161 timestamps.

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.

Python wrapper around a small subset of the OpenSSL library. Includes: X509 Certificates, SSL Context objects, SSL Connection objects using Python sockets as transport layer. The Connection object wraps all the socket methods and can therefore be use

Clipperz is a web based password manager. Local encryption within the browser guarantees that no one except you can read your data. A true zero-knowledge (or host-proof) web app!

CryptoPad is a Java based file encryptor ! It can encrypt every type of file. The icing on the cake is that it's 100% cross-platform. i.e. You can run the same .jar file on Windows, Mac OS, Linux and any OS capable of running JRE 8 :) CryptoPad uses AES-128 bit symmetric key encryption to secure your data.

File Crypter is a Simple program, that is able to encrypt your files and decrypt them. A version of File Crypter is included as an example in the xCrypter Library and is called "ncrypter" which is short for "new crypter".

KpGen is an modern Password Generator. It has some interesting features, like a random generator based on mouse move with some strong options. It can also work as a hash calculator, calculating hashes of passwords and phrases.

FEHASHMAC is the largest collection of publicly known hash algorithms integrated into a command-line utility. FEHASHMAC contains a set of known test vectors and results for each algorithm such that the correct implementation for each hardware platform and compiler version can directly be verified. Currently 57 hash algorithms like sha1 sha224 sha256 sha384 sha512 and variants, sha3 and shake, all SHA3 finalists and blake3, md2 md4 md5 md6, rmd128 rmd160 rmd256 rmd320, whirl gost lash160 lash256 lash384 lash512 tiger2 and RFC 2104 HMAC and KMAC support are included, plus SHA3 extensions kmac128, kmac256, kmacxof128, kmacxof256 for message.

Novus Ordo Seclorum (Ordo for short) is a pathologically secured, invitation only secure communications framework. It is built on top of the Freenet crypto libraries.

Cross platform GUI managing bookmarks and shortcuts in a portable way. Support import/export, search, encryption, hierarchical tags, USB key installation, various environments integration, OS-dependent shortcuts, plugins extensibility.

Check out the cppcrypto web site linked below for programming documentation.

Command-line strong encryption tools including: triple cascaded encryptor, multiple hash calculator and multiple block cipher encryptor. Supports AES, Serpent, Twofish, SHA-512, RIPEMD-160, MD5 and other algorithms.

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 :-)

The In-Browser File Encrypter is a simple web application that enables you to securely encrypt your files directly in your browser using the AES-256 encryption algorithm in CBC mode. Check it out at: https://codepen.io/Northstrix/pen/xxvXvJL and https://northstrix.github.io/In-Browser-File-Encrypter/V1.0/web-app.html GitHub page: https://github.com/Northstrix/In-Browser-File-Encrypter The download shortcut: https://sourceforge.net/projects/in-browser-file-encrypter/files/V1.0%20%28Improved%20UI%29/V1.0%20%28Improved%20UI%29.zip/download Successfully tested in Google Chrome on Windows 11 and Fedora 40.

With this tool you can create and sign x509 certificates, certificate request, create self-signed certificates, RSA private and public keys with simple and intuitive GUI. This program is using OpenSSL.

This program can encrypt / decrypt strings with the Caesar's Cipher. It also can try to crack an encrypted string with brute force. (C) Daniel Steinhauer <pik-9@users.sourceforge.net>

Cryptography Tools is a project to develop demonstration tools on classic (currently Caesar and Playfair) & modern crypto-systems, including private & public key encryptions, digital signatures, cryptographic hashes and authenticated encryption.

DCrypt is an encryption and decryption tool that combines in a smart way multiple algorithms. The combination of multiple strong algorithms makes it much more difficult for hackers to get the plain content of the encrypted file without the password.

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