mBuddy is a project with the initial goal of allowing users of mobile devices (Java, J2ME) the option to find others based on interests, diet & other factors. Objectives are to allow intelligent, conditional, secure exchange of contact info, A/V & more.

This project develops an application to provide PGP functionality (encrypting, decrypting, and verifying text and data using asymmetric keys as well as managing these keys) on devices supporting PersonalJava (eg. mobile phones like the SonyEricsson P800)

Team MONICA's effort: - general JAVA environment - general JAVA cryptography environment - SSH client/server in JAVA - secure & anonymous communication

mrpeadata is a cross platform password / to-list manager. It is written in Java and is designed to be very secure.

mystic-crypt is designed as a Java library that can be used for simple and complex encryption and decryption. The source code for the library is available under https://github.com/astrapi69/mystic-crypt For demonstration what the library can do there is a graphical client: The source code for the ui is available under https://github.com/astrapi69/mystic-crypt-ui

obov stands for OATH Based OTP validator. It's a 100% pure Java library that provides simple to use methods to validate (and related utilities) one time passwords generated by OATH compliant devices.

odfsec is a toolset for validating digital signatures in odf (open document format) files. The tools are independent of any office suite software and may be integrated into backend workflow processes.

The Open Protocol for Access Control Identification and Ticketing with privacY, is a standard suite of Key Establishment and Authentication protocols based on ECC and AES, for optimized contactless transactions and simple PKI based Key management.

OpenILP is a project to advance the participation of citizens in the democratic life of the country as an ALTERNATIVE to political means. This enables the digital signature legally recognized and advanced in eGovernment.

Rot13 decoder for cellphones (j2me).

The iText based PDF sCramblEr allows you to encrypt a PDF using one or more public certificates of the addressees (one or more .cer files). For each .cer file, you can enforce specific PDF permissions: (dis)allow printing, (dis)allow modification,...

Samizdat is a toolkit for Java for building Kerberos secured distributed, message-oriented applications. The toolkit contains base classes that simplifies the management of Kerberos login contexts as well as flexibly sign and seal messages between principals using the Java GSS API. The toolkit contains Transformation classes for Kerberizing JMS traffic as well as a super-lean HTTP based protocol stack that supports both Synchronous (RPC) and Asynchronous modalities.

sanesigner is a high level digital signature api component. it support generating and verifying digital signatures as well as encryption and decryption using public keys, and lots of other features in between.

Secure and portable command-line password manager written in Java and based in the existing sf JRijndael project.

Using encryption to secure your code or text. Click File->Run to run your code using Ruby, see the pop up for output. Never save your text or code to disk unencrypted. Don't forget your password. Encryption is error-persistent.

An ultrasecure communications server and clients for *NIX and Windows hosts.

Shasummer is a SHA hashsum utility in Java. It can calculate SHA1, SHA256 and SHA512 hashes of a file or of a directory (and its subdirectories) and verify the hashes later. Shasummer has a graphical and a command-line interface.

Java Multiplatform project to offer a service to the digital sign of PDF files. Features: - PKCS11 (Smartcard), PKCS12 (Software). - Barcode PDF417. - Timeserver TSA. http://www.sinadura.net

Sirius-Sign is a signing and verification server with it's focus on high throughput and easy integration into an existinig landscape. For signature creation smartcards with OCF and PKCS11 interfaces are supported. An EJB container is required.

The Secure Java Code Filter (SJCF) provides an ICAP-based filter mechanism for mobile Java code and the signatures applied to it. Administrators can define a centralized policy determining which applications and signatures respectively are allowed.

SJEA version 1.0 - Simple Java Encryption Algorithm. SJEA is a simple command-line binary encryption algorithm (symmetric block cipher) written in JAVA. It uses a password and a byte-vector array to scramble the input file.

Java library with Cryptographic algorithms. Easy to use Crypto algorithms. Works on Windows, Linux, Android. No external lib dependencies, no useless abstractions, no 'crypto provider'. Elliptic curves was borrowed from BouncyCastle and simplified a lot. Most of EC classes are custom algorithms for certain curves. Can be easily deleted if u dont need them. With couple of classes u can parse and construct those ugly ASN.1 structures, look at RSA and EC key formats for example. No bad dependencies between classes, so u can easily cut off unnecessary code and simply include what u need in your project. Feel free and simple without headache. We are using class Binary as best for us to work with byte arrays. Simple classes for console-like colored apps in GUI-mode. Look also http://demo.sls.team

spule stands for "secure practical universal lecture evaluator". spule is a program to automatize the evaluation of lecture polls.
