HashTool calculates the most common hash and hmac values of files and strings by using the "Bouncy Castle Java cryptography API".

A Secure Diary Program written in Java and using the bouncycastle JCE Cryptograpic library. It uses a combination of BlowFish and TripleDES (XORed) to encrypt Diary entries.

yaSSL, or yet another SSL, is an embedded ssl library for programmers building security functionality into their applications and devices. yaSSL is highly portable, and runs on standard as well as embedded platforms(QNX, ThreadX, VxWorks, Tron) yaSSL is still available but no longer being developed. Current development on the same project continues under wolfSSL. Visit yaSSL Home above for the latest stable release.

DecodeBase64 does exactly what the title says: it decodes strings encoded with the Base64 algorithm. Source code is provided in both Java and C++.

This is an android application able to perform AES-128 bit encryption on all types of files. Its tested encryption speed for 1080 HD video on android device is 3.43 MB per second, and decryption speed is 6.25 MB per second for android device with 3 GB RAM and MT6735 Quad-core 1.3 GHz CPU.

The end goal of the FreeMess Project is to produce a cryptographically secure, pseudonymous, cross-platform peer-to-peer Instant Messenger service, piggybacking on FreeNet (http://freenet.sourceforge.net) as a distributed filesystem to hold user data.

GDigiDoc is a GUI frontend built with GTKMM for DigiDoc (alias OpenXAdES - http://www.openxades.org) library allowing users to create digitally signed documents and verify signatures of other users. Signatures follow the XAdES (alias ETSI TS 101 903) and

The GPGUI program is GUI wrapping GnuPG functionality provided by Bouncy Castle. The program allows you to encrypt/sign/decrypt text messages and files using asymmeric PGP keys. The program can read and manage GnuPG keys if GnuPG is installed. But the program also maintains its own secret and public key files and having GnuPG installed is optional.

Simple Encrypted chat application built with Java. It uses AES-256 bit block cipher algorithm.

ISO18013 Electronic Driving License Java reference implementation. The project implements the host API for reading out ISO compliant electronic driving licenses and a Java Card applet that implements the standard on a smart card.

An open source Java/Java Card implementation of the ISO7816 and related PKI standards.

This library provides a SecureRandom service, integrated with the Java Security API, for accessing random.org and random.irb.hr (true random number generators that generates randomness via atmospheric noise or photonic emission).

PCSecrets is a PC application that holds secret text data - protected by a master password and strong encryption. Use it as a password manager or just somewhere to hold any text data securely in one place. It can hold a second, hidden set of secrets that is undetectable and plausibly deniable. The program is also a PC counterpart of the Secrets for Android app. It uses the same data structure and provides synchronization that allows easy transfer of secrets between the two. For those who find the personal computer environment more comfortable for data entry and editing (i.e. a real keyboard), PCSecrets provides an alternative way to manage your secrets. Sync is also effectively a form of backup. To enable the sync feature with Secrets for Android, you need to install the PCSecrets Sync app, downloadable from SourceForge or Google Play. PCSecrets import plus PCSecrets Sync provides a route to importing secret data into Secrets for Android that would not otherwise be possible.

Crack the encrypted passwords (MD5,SHA, etc....)

Java based Portable hashing application capable of multiple individual file signatures or proprietary group signatures (1 signature for a folder and all its contents). GUI and command line in the same executable. -sha1 -sha256 -sha51 -md5 -crc32

A text editor which saves data encrypted with strong cryptography (AES, Blowfish..)

Starting as a personal study project, I have decided to share this security project. For now, it is a JAVA program that can be used to encrypt and decrypt simple file content (ie files), possibly later evolving into a utility with user interface and/or a library

AESTextCrypt is an easy-to-use open source tool for text encryption and decryption. Primarily intended for use with email, use it wherever you need to protect text from prying eyes. The encrypted text can be copy/pasted into any text-handling application (e.g. email) instead of plain text. Convenience buttons are provided for clipboard operations. AESTextCrypt uses AES-256 bit encryption which is the strongest available encryption scheme. It also employs bcrypt, which implements key-stretching and an adaptive key setup phase, the complexity (number of rounds) of which is automatically set to match the processing power of the encrypting computer. This makes it highly resistant to dictionary attack. AESTextCrypt is written in Java, so can be run on all desktop platforms - Windows, Mac and Linux.

The AWS Encryption SDK is a client-side encryption library designed to make it easy for everyone to encrypt and decrypt data using industry standards and best practices. It enables you to focus on the core functionality of your application, rather than on how to best encrypt and decrypt your data. The AWS Encryption SDK is provided free of charge under the Apache 2.0 license. With the AWS Encryption SDK, you define a master key provider (Java and Python) or a keyring (C, C#/.NET, and JavaScript) that determines which wrapping keys you use to protect your data. Then you encrypt and decrypt your data using straightforward methods provided by the AWS Encryption SDK. The AWS Encryption SDK does the rest. Without the AWS Encryption SDK, you might spend more effort on building an encryption solution than on the core functionality of your application. By default, the AWS Encryption SDK generates a unique data key for each data object that it encrypts.

A product which would help you walk the thin line between security and user-friendliness.

AleHu is an open source encrypted message transfer system that encompasses both server (PHP) and client software (Java). Give it a shot: You can try out AleHu by simply running the client using the preconfigured AleHu test server! For further details and instructions on how to quickly install and run AleHu, have a look at the documentation in the Wiki section.

Encryption plugin for Alfresco. Enables the user to crypt and decrypt (it handles the 'pkcs5' MIME-type). This is a component of the IDX-eDOC project (OpenTrust suite), contributed by IDEALX

The aim of this android application is to provide a secure storage for files on the phone. By using asymmetric cryptography the application allow the user and other apps to encrypt the files using a public key so without the need of a encryption password.
