Open Source Java Cryptography Software

Cryptomator is a free and open source project that offers multi-platform, transparent client side encryption of your files in the cloud. It works with just about any cloud storage service; is totally transparent so you can work with your files how you normally would; and secure with a 256-bit key length AES encryption. It’s also simple and easy to use with no need for different accounts, key management, cloud access grants or cipher configurations.

EJBCA is an enterprise class PKI Certificate Authority built on JEE technology. It is a robust, high performance, platform independent, flexible, and component based CA to be used standalone or integrated in other JEE applications.

CrococryptFile is a file encryption tool which creates encrypted archives of files and folders. The encryption features of CrococryptFile can be compared to a ZIP utility that uses ZIP's AES encryption. However, there are significant differences. CrococryptFile... - encrypts all file and folder information including filenames, time/date and filesize information, - disguises any information of the archive's content, because all data and meta-data is simply integrated into a giant file dump. =Crypto Suites= For a full list of and details about supported crypto suites, please visit the CrococryptFile Homepage. Examples: - Password-based encryption (following PBKDF2) with AES-256, Twofish, Serpent, ... - Public key encryption using GPG/OpenPGP, Windows Keystore/CAPI with RSA/X.509 certificates - Cloaked (headerless) Password-based Encryption (AES-Twofish-256 cascaded) - ...

An open source implementation of the FIDO2 protocol to support passwordless strong authentication using public-key cryptography. Supports registration, authentication (all platforms), and transaction authorization (for native Android apps).

Cracx allows you to crack archive passwords of any encryption using 7-zip, WinRAR or a custom command, via Brute Force or Dictionary attack. Note: You must NOT use this program with files you don't have the rights to extract/open/use them! Currently, the program requires a current version of either 7-zip or WinRAR to be installed, but you can also use it to bruteforce basically anything that is executably via command-line with custom parameters. On an i7 CPU, it runs approximately 30 combination tests per second. Feel free to make suggestions or contribute by implementing features and translating the tool into your native language!

SSL-Explorer is a fully-featured, web-based SSL VPN server. This project is no longer actively maintained as the SSL-Explorer technology has now been acquired by Barracuda Networks, Inc.

HashSum is a .NET port from GNU's md5sum and sha1sum. It supports: hash algorithm selection between MD5 and SHA1 (more could be added later) and compatibility between HashSum and GNU's checksum file format

The wolfSSL embedded SSL library (formerly CyaSSL) is a lightweight, portable, C-language-based SSL/TLS library targeted at IoT, embedded, and RTOS environments primarily because of its size, speed, and feature set. It works seamlessly in desktop, enterprise, and cloud environments as well. wolfSSL supports industry standards up to the current TLS 1.2 and DTLS 1.2, is up to 20 times smaller than OpenSSL, offers a simple API, an OpenSSL compatibility layer, OCSP and CRL support, is backed by the robust wolfCrypt cryptography library, and much more. wolfSSL relies on the FIPS 140-2 validated wolfCrypt library for all cryptographic functionality.

Bias is a cross-platform versatile information management application / Organizer

Ank Zipper provides you with a lightweight, Java-based application designed to provide security to your documents. Ank Zipper can compress both files and folders and create password-protected archives, in order to prevent unauthorized access to important files. Additionally, it can be used for extracting or simply browsing ZIP files.It includes AES(Advanced Encryption Standard) algorithm to encrypt/decrypt file(s). Ank Zipper is a cross-platform software that can be used on any platform that features Java compatibility (e.g. Mac OS X, Linux, Windows).

Identityflow provides a framework for building protocol flows that perform distributed Identity operations. Examples of Identity Operations are Single Sign-On (SSO) and Attribute queries.

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.

Infranet is a system that attempts to circumvent web censorship by allowing clients to surreptitiously request sensitive content via cooperating Web servers distributed across the global Internet.

Backup P2P is a peer to peer application doing automated and secured backups inside a community (Jabber, XMPP). Each user shares some available space on his disk with others, to be able in return to remotely backup some of his own data.

Barada (Barada Aint Respecting Any Deceptive Adversaries) is a PAM module designed to provide two-factor authentication support. There is companion software called Gort which runs on Android devices, essentially turning your phone into a SecureID token. The PAM module is available in the repositories for Debian based distributions. Gort, the Android client, is available from the android market (https://play.google.com/store/apps/details?id=net.sf.crypt.gort)

Bork is a very small, cross-platform file encryption utility. It is written in Java and designed to be included along with the files it encrypts for long-term storage (eg on CD-R). Its minimal external dependencies make it fairly futureproof.

CertForge is a web-based certificate utility written in Java 1.6, to make or view X.509 certificates, keys, CRLs, manage keystore and truststore (CTL) for SSL sites, and run as a simple Certificate Authority (CA).

How do you find anything in the mountain of data on your PC? How do you organise, maintain, archive and protect your files? How do you avoid surrendering to the Powers of Darkness? Checkpoint Commander, the vital tool for Information Management!

A secure and centralized way to get checksums of common downloads. You will find the usual MD5 hash, but also the newer and more secure hashes like SHA-1, SHA-256 and even SHA-512. If the filesize and all up to four hashes match, you should be save to use that downloaded file.

Commons-SSH is a thin bridge between different Java SSH implementations libraries. It doesn't contain any crypto-related code and created to be used by projects who doesn't want to care about export control regulations (let client to decide)

Encrypti is a multi platform, easy to use encrypting tool for keeping your files secure. This application offers portability of encrypted files between various platforms. Secure your files with Encrypti!

Java based API (library) and console utility for cross-platform file and directory encryption and archiving. Encrypts single files up to 9.2 EB length. Directories can be encrypted as sets of single files in a single action. Uses Twofish (CBC) and SHA-256. Security level is strong and benefits from the PWS3 (Password Safe) encrypted file format. The level can be lowered to 128-bit key-length (normally 256).

This java tools design to decrypt and obtain the MS Windows Admin password from encrypted password get from Amazon EC2. It can run as standalone application or embedded as Java applet in HTML.
