The Martus (TM) Bulletin System is used by human rights and social justice groups to track violations. This Java program is as easy to use as email. Bulletins can be encrypted or searched, and can be backed up to a remote server. See www.martus.org.

Meergoose is a multi-use social suite of applications that allows users to setup a portal on their personal computing platform that encrypts and stores files locally and synchronizes encrypted files with a secure cloud. MeerCrypt is a component of Meergoose and is opensource. The vision is simple: Encrypt Locally. Share Remotely. YOU remain in control of your security, your keys, your data.

Messa is a fully distributed instant messaging and presence application.

a small library for cryptography (e.g. for the MicroEdition of Java) that supports AES (256 bit only), SHA-512 and CBC. The library is available in Java and JavaScript.

MicroSafe is a J2ME 1.0 application to store and access notes in a hierarchical data structure (outline) on mobile devices (CLDC - Connected Limited Device Configuration). Notes can be encrypted to store data like PINs, passwords, etc. securely.

MirandaFile is an encoding scheme unlike any other. It is, as far as I know, entirely unique.

mkpass is a simple command line utility to generate secure random passwords. You can easily redirect these to a clipboard or copy and paste as needed. I use a password manager and generate random passwords every time I need one. And while most password managers include a generator, there are times I need one outside of that. The code is written in java so it should run on any OS that supports it. Lastly, the idea and core code came from a Wikipedia article. I just took this and expanded upon it. https://en.wikipedia.org/wiki/Random_password_generator This is a single executable JAR file. While you will need Java installed, there is no need to install this program. Just download the JAR file, please it somewhere convenient, and execute it from the command line: java -jar mkpass.jar See home page for additional details and usage instructions. https://github.com/frossm/mkpass

This project tries to supply some randomness extractors' implementations written in JavaME for further use in cryptographic mobile applications.

The Remarc Mobile-ID USAT applet this is a JavaCard applet with USIM Application Toolkit menu support. Basic functions of the Remarc Mobile-ID SAT applet: • Authentication function; • Signing function; • Changing PIN1/PIN2; • Changing PUK; • Unblock PIN1/PIN2; • View information - in a USAT menu is present a menu item with information of PIN usage.

XY modular Polynom manipulation in Java for calculating elliptic curves point order

The Moonbounce API is a set of high level objects that encapsulate pieces of the Bouncycastle lightweight crypto API. Moonbounce significantly simplifies RSA key generation, signing, encryption/decryption and verification of both byte arrays and files.

Our idea is to deploy a society of computational agents that collaborate in order to achieve the shared goal of decrypting a chunk of ciphertext or recovering a password from an hash by means of a dictionary-based attack.

MySafenote is designed to help you keep your login credentials safe. The application creates a secure password database that can be encrypted in order to prevent unwanted access to this type of sensitive information. MySafenote protects the created database with a user-defined master password. You can then decrypt the password file with a single click.

A cryptographically secure instant messaging application. All packets sent by this program are encrypted.

If you need to protect your confidential files in office or shared desktops, here is the robust command line and GUI utility to do password based encryption using AES. It can encrypt and decrypt a folder structure containing any number of files.

The main philosophy of the project is "the best protection a bad password can give". People will choose bad password as long as they have this option, so Neocryptex builds a strong crypographical defence between the password and encrypted data.

NimpSmartCard is a framework to interact with smart cards through PC/SC readers as well as test/production readers such as Micropross and Smartware. The framework comes with sample tasks and a sample terminal manager which supports scripts and logs

The NinthTest JCA Provider is a security provider for the Java™ Cryptography Architecture, focused on supporting candidate, reference, academic, and experimental cryptographic algorithms and security services. Because the services provided by the NinthTest JCA Provider are exploratory/provisional in nature, the NinthTest JCA Provider is not recommended for use in security-critical applications or environments.

Novel Insight Inner Circle is a message and file encryption tool for Windows. The software is developed in Java and requires 64bit Java JRE. The encryption uses AES-256 twice so it is harder to crack than the industry standard pure AES 256bit implementation (theoretical key size is 512 bit). The software writes encrypted data in ASCII text format which can be cut'n'pasted to messaging apps or to emails and back to Inner Circle when decrypting data. IMPORTANT: The software requires new OpenJDK 16 (Not Oracle's J2RE 1.8) to run. Install, for example, AdoptOpenJDK for Windows. NOTE: By using encryption twice the implementation is (in theory) vulnerable to Meet-In-The-Middle attack reducing key size to 256bit but the attack still requires 2^256 bytes of memory making it impossible in practice.

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.

A command line interface for encryption and decryption using the NTRU cryptography algorithm. "NTRU is a public key cryptosystem that is considered unbreakable even with quantum computers. Commonly used cryptosystems like RSA or ECC, on the other hand, will be broken if and when quantum computers become available."-NTRU

OODVS is a Java framework which goal is to increase the Java runtime support for Object Oriented Distributed Virtual Systems providing local access to distributed resources via proxies.

ObscureEncrypt is a high level security encrypter. It encrypts at three levels, 448 bit Blowfish encryption, Obscurity, high level encryption. Making it almost impossible to decrypt

A crossplatform key manager for GnuPG.

OceanStore is an architecture for a global-scale file system which uses erasure coding, cryptography, and Byzantine agreement to provide available, highly durable storage in a peer-to-peer environment.
