JonDo 00.16.001 - Protect your privacy on the Internet (was Java Anonymous Proxy).. (Free): "

JonDo (was Java Anonymous Proxy) is a free, open-source and highly portable (Java-based) client software for accessing the JonDonym services. Its primary use is the anonymisation of web site requests against web site operators, internet providers and the anonymisation service Operators. All requests of the web browser have to be processed by the JonDo program instead of accessing the internet directly. JonDo encrypts the data and sends it to the first Mix of a Mix Cascade. The first Mix then mixes the data with that of other users and sends it to the second mix station which passes it on to the third mix station which decrypts and sends the data through a cache proxy to the internet.

Each mix carries out cryptographic operations on the message so that the JonDo-encrypted data is only readable after having passed through the proper mixes in the proper order. This ensures that an eavesdropper either only receives unreadable (encrypted) data or can no longer determine the sender. In order for it to work correctly, only one mix in the cascade needs be trusted not to inform the eavesdropper about the method of message mixing. The more users that use the cascade, the harder it is for an observer to distinguish single users.

Data retention resistance - By the distribution on different, independent operator organisations and countries, the JonDonym service is secure against data retention. Even if single operators have to store data, this does not create an 'overall picture' needed to uncover the identity of users. Thus, JonDonym provides maximum protection against operators and third parties.

Moreover, the system provides so-called forwarding functionality. Users can connect to the service even if it is blocked by their provider. This is often the case in countries that are known for heavy censorship. Unblocked users of the service (Forwarding servers) may voluntarily forward other JonDonauts (Forwarding clients) to the Mix Cascades.

Version 00.16.001:

New features:

• Security: show warning if user does not use JonDo and maybe only thinks to be anonymous
• Security: try to switch current service on startup if it has only one mix
• Security: only if connection to all other services failed, automatic switching to one-mix services is allowed
• Security: integrity error notification
• Comfort: Added support for multiple download sources for new versions of JAP.jar
• Comfort: introduced temporary whitelist attribute for trust model, that enables the user to temporarily connect to filtered services
• Comfort: merged all filters/trust models into one single, editable trust model
• Comfort: JonDoFox users now get a clear error message if JonDo im niht-anonymen Modus ist and if they try to access a blocked HTTPS site
• Comfort: transferred bytes are now shown in kilobytes

Bug fixes:

• allow all JonDonym related websites even if access to all websites is blocked
• fix for warning about correct JonDo usage
• fixed some bugs related to automatic cascade switching
• some debug entries for InfoService
• fixed global timeout for InfoService requests
• remove 'initial dummy cascade' whenever possible, also if auto switching is disabled
• fixed possible null pointer in XMLSignature
• fixed language selection for payment options
• fixed view of amount to pay for cash and money transfer payment methods
• fixed possible deadlocks and null pointers in DirectProxy
• show low balance popup only if no other full account is available
• fixed deadlock in DirectProxy caused when interrupting running request threads
• fixed possible double-binding of default listener
• stop connection attempts if auto-switching is disabled and payment is mandatory

Other:

• new random order for services on every startup
• show current service on top in popup menu
• automatically switch to next service if current service is filtered and 'getNextCascade()' is requested
• X-Headers are now always active
• keep reconnect on error if current service is initial dummy service
• ignore performance filter if no performance data is available at all
• connection to user defined services is now only allowed within the current trust model
• create self-verified signatures
• request all InfoService documents with http compression
• reduced InfoService requests for InfoServices and Mix cascades
• clearer HTML messages for DirectProxy
• show squid error pages if forced by last mix operators
• new JonDoFox headers
• enhanced DirectProxy error page presentation
• clearer HTML 'not-allowed' messages for DirectProxy requests
• if only premium services are available, the ConfigAssistant is now shown instead of closing the connection
• ConfigAssistant now tries to connect automatically if it has been called because of a connection timeout; the user thus quickly sees the reason for the connection problem
• do not show 'free' filter if free services are not allowed
• added security warnings for user defined services
• removed warnings about 'no JonDoFox' and 'insufficient bytes for download'
