Here at the Bouncy Castle, we believe in encryption. That's something that's near and dear to our hearts. We believe so strongly in encryption, that we've gone to the effort to provide some for everybody.

Apache Shiro is an easy-to-use application security framework that cleanly handles authentication, authorization, enterprise session management and cryptography. Our mission: To provide the most ... [More] robust and comprehensive application security framework available while also being very easy to understand and extremely simple to use. [Less]

EJBCA is a fully functional Certificate Authority. Based on J2EE technology it constitutes a robust, high performance and component based CA. Both flexible and platform independent, EJBCA can be used ... [More] standalone or integrated in any J2EE application. EJBCA is an enterprise class PKI, meaning that you can use EJBCA to build a complete PKI infrastructure for your organisation. If you only want to issue a few single certificates for testing, there are probably options that will get you started quicker, but if you want a serious PKI we recommend EJBCA. [Less]

I2P is an anonymous network, exposing a simple layer that applications can use to anonymously and securely send messages to each other. The network itself is strictly message based (ala IP), but there ... [More] is a library available to allow reliable streaming communication on top of it (ala TCP). All communication is end to end encrypted (in total there are four layers of encryption used when sending a message), and even the end points ("destinations") are cryptographic identifiers (essentially a pair of public keys).

This is a simple program written in Java that tries to find a hash by using a dictionary file. It can be as good as the dictionary used in it. The dictionary file is not included. If you have better ... [More] ideias for this code, just let me now :) DISCLAIMER: This tool is for educational purposes only. It shows how bad it is to have weak passwords such as known words like "master" or alike. [Less]

Mailets which encode, decode, sign and verify mail plus cryptology utilities.

MACSCryptPowerful cryptography algorithms implementation, with several user interfaces for the demonstration, but you still can access each separate algorithm from a simple API, you can even have a ... [More] single library for specific algorithm without needing to include everything ... Integrating MACSCrypt into your code is very simple, it's just one line code needed: //DEFINING THE OBJECT: MACSCrypt macsCryptObj = new MACSCrypt(); //DEFINING ALGORITHM AND MODE: macsCryptObj.Algorithm = MACSCrypt::CALGORITHM::AES; //Or DES or DES3 or AES3(NEW!) and implementing ... macsCryptObj.Mode = MACSCrypt::CMODE::EBC; //Or CBC or CTR or OFB or much more, and inventing ... /*** AND here is the line: ***/ ... read more at the project homepage ...

SmartConfig is a Java library for easy access to configuration parameters. It has support for strong (both symmetric and asymmetric) cryptography and cluster-wide configuration sharing.

Backup P2P is an open source peer-to-peer backup system doing automated and secured backups inside your own trusted community (Jabber, XMPP). Each user shares some available space on his disk with ... [More] his contacts, to be able in return to remotely backup some of his own data. Advantages: * Backups can be scheduled in any time range that suits you. * Backup P2P uses the Jabber IM community, which counts over 200 million users. * Data is encrypted using the well-proven standard AES 128, but soon-coming version will allow to use different cryptographic providers and custom key length. * We use a rsync-like algorithm/protocol to perform incremental backups and thus limit the bandwidth require [Less]
