Conscrypt is a modern TLS/SSL provider for Java that replaces the default JCE/JCA crypto stack with one backed by BoringSSL for better performance and security posture. It is implemented as a drop-in SecurityProvider, so applications and frameworks can opt in without changing high-level HTTPS or socket code. The provider focuses on contemporary protocol hygiene—up-to-date cipher suite selection, ALPN, session resumption, and hardened defaults—so Java servers and clients negotiate secure connections by construction. Because it builds on BoringSSL’s audited primitives and constant-time implementations, it reduces the risk of subtle side-channel issues while improving handshake and bulk crypto throughput. Conscrypt also exposes platform accelerations (like AES-GCM and ChaCha20-Poly1305) and supports features important to HTTP/2 and HTTP/3 stacks. Its goal is pragmatic: deliver a fast, well-maintained TLS provider that behaves like modern browsers and mobile stacks.

The Cookie-revolver framework provides J2EE web-applications with two-factor authentication security, “something I know” (userid/password) and “something I have” (encrypted one-time cookie).

Correlation engine based on Esper library which can be used together with Logstash. Please read FAQ http://sourceforge.net/p/correactive/wiki/FAQ/

CrococryptQuerl =============== CrococryptQuerl (CQuerl) is a web-based open-source file encryption and file exchange tool. If you trust the application service provider which is running CrococryptQuerl, it can be seen as an "anonymous & encrypted safe deposit box for computer files". ---INTRO--- The encryption is done on-the-fly using the user's password. Of course, this requires a trusted TLS/SSL connection to the server running CQuerl. The user provides a file and password and receives an ID. No plaintext data is stored in CQuerl including filenames. If the user looses the ID or forgets the password, the encrypted file cannot be recovered - even by the service provider. DOWNLOAD ======== * A demo running on Google's App Engine (GAE) can be found here: https://crococrypt-querl.appspot.com ==> GAE limits the files to be uploaded to 1MB(!). ==> The file database will be cleared occasionally. ==> Crypto seems to be working slowly on GAE, so be patient! ;)

Crypt-EG is an easy visual cryptosystem program that implements ElGamal method using elliptic curves.

Cryptographic Java library for creating, maintaining, persistence and use of cryptographic entities.

Cryptex Box is an encryption software written in java for password storing. It's easy to use, very fast and small. Is cross platform (win, mac, linux) and does not require any installation process.

The Crypthing project aims to develop cryptographic software for business, government and personal use within the context of Brazilian Public-Key Infrastructure.The first delivery is an application to sign documents for non-repudiation purposes.

Cryptix is an international volunteer effort to produce robust, open-source cryptographic software libraries. Cryptix products are free, both for commercial and non-commercial use and are being used by developers all over the world.

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

Update: The code from this project has been contributed to the GNU Crypto project. The Cryptix SASL Library is an implementation of the Java SASL bindings and a number of SASL mechanisms.

This is a JavaScript library which gives the ability to use cryptographic functionality abstracted of available technologies on the browser side. It executes a cryptographic function with the fastest technology including Java, JavaScript and Flash.

This pack includes the following: FCSG - generate checksum and perform file comparison; JCryptoTool - encrypt/decrypt messages and files; JWallet - password protect sensitive information. See Help menu in each application, Source code included.

v2.0.0 (Latest) ---CHANGE LOG--- v1.0.0 - Original Release v1.0.1 - Source Code Cleanup v2.0.0 - Now Features File Encryption Protect your privacy! Encrypt your messages and files with a cryptographic strength of up to 256 bits before sending them to others!

Cryptography Workshop is a small yet powerful tool for cryptography and cryptanalysis. It's focused more on classic cryptography. It is currently in alpha and under development.

With this application you can encrypt texts or files and chat with friends. You can download a early Android version of the chat client from here: https://drive.google.com/uc?export=download&id=0BwePHaWdtoMweWRyMExqbHZyUEk Hint: I started this project because i have fun to write java apps. This app is not professional. I don´t recommend using this to encrypt very important data (for example of your company ...). Keep this in mind. Happy testing! ;) Please check MD5 after Download. You can find this on the official site of this project (german). You can find a link to this very simple site below. How to start: -------- Windows: double-click on CryptolinN.exe -------- Linux: sh CryptolinN.sh OR FIRST chmod +x CryptolinN.sh THAN ./CryptolinN.sh -------- Console: java -jar CryptolinN.exe --help N = version number

It is a program to save account (username, passwords). You can import/export files. Set shortcuts for frequent used account. Update/delete data. It is a multiuser program (one password to remember all others). Link: http://youtu.be/0PR--cf2En4

Pure-Java cryptographic calculator, featuring basic arithmetic operators, cryptographic operations, multiple key file formats and edition of ASN.1 object files.

Cygnus Editor is a basic text-editing program created entirly in Java. And it's most commonly used to view or edit text files (.txt). A text file is a file type typically identified by the .txt file name extension. In Cygnus Editor you can encrypt your text document, so nobody can see the content of your document. Also you can decrypt your document and edit it. Cygnus Editor uses AES-256 encryption. AES-256 is the most powerful encryption standard yet. AES-256 uses many applications, websites and networks to secure their data. And now you can secure your document with Cygnus Editor.

DAD is a Windows event log and syslog management tool that allows you to aggregate logs from hundreds to thousands of systems in real time. DAD requires no agents on the servers or workstations. Correlation and analysis is driven through a web front end.

Privacy-preserving proxy for digital credentials transactions

A simple DOS attack tool based on the public resources response time.

DROID FINDER will help you to track your phone, identify the user taking a picture using the front camera (i.e. if available) and provide the geographic positioning of the device sending you a SMS with a google maps link.

Starting July 2026, StrongKey will start distributing new releases of its open-source software with digital signatures using the W3C XMLSignature (DSIG) standard. This project distributes CLI and GUI versions of software that can verify the signed package containing the content, signature and certificate chain.
