Free anonymous https proxy software for linux

IP::Anonymous is a Perl port of Crypto-PAn to provide anonymous IP addresses.

SYNOPSIS

use IP::Anonymous;
@key = (0..31);
my $object = new IP::Anonymous(@key);
print $object->anonymize("192.0.2.0")."n";

This is a Perl port of Crypto-PAn. Crypto-PAn is a cryptography-based sanitization tool for network trace or log data. The tool has the following properties:

One-to-one

The mapping from original IP addresses to anonymized IP addresses is one-to-one.

Prefix-preserving

The IP address anonymization is prefix-preserving. That is, if two original IP addresses share a k-bit prefix, their anonymized mappings will also share a k-bit prefix.

Consistent across traces

Multiple traces can be sanitized in a consistent way, over time and across locations, even though the traces might be sanitized separately at different time and/or at different locations.

Cryptography-based

To sanitize traces, trace owners provide a secret key. Anonymization consistency across multiple traces is achieved by the use of the same key. The construction of IP::Anonymous preserves the secrecy of the key and the (pseudo)randomness of the mapping from an original IP address to its anonymized counterpart.

This Perl port of Crypto-PAn uses similar logic to that found in Crypto-PAn 1.0, but most importantly maintains consistency in the process so that regardless of implementation, using the same key in each will give consistent results.

USAGE

$object = new IP::Anonymous(@key)

Initializes the electronic codebook object with a 32 8-bit decimal array. This array, consisting of 32 decimals between 0 and 255 inclusive, is the user defined private key for this anonymization session. This 256 bit key should be kept private. The key can be used across sessions to maintain consistent mappings between the original and the anonymized IP addresses.

$object->anonymize($address)

Called with a dotted quad IP address string (e.g. 192.0.2.0). Returns an anonymized version of that IP address as a dotted quad string.

BlockStop Proxy is a Firefox extension that allows you to view the current page or link using.

Adds a "View this page with BlockStop" or "Open Link Target with BlockStop" option to your Firefox right-click menu, depending on where you click. The BlockStop Proxy extension automatically encodes the target url to maintain anonymity.

Anon Proxy Server is a fast http, https, socks caching proxy server. Easy web based configuration, optional p2p anonymous mode.
Main features:
- Easy Configuration - Web based, no editing text configuration files.
- Memory - No big databases are kept in memory, no matter how large the cache is, memory usage will only increase when more users access it at the same time.
- Speed - To see how much cpu the proxy uses, run top or task manager. Then open multiple windows and hit reload continously, on my computer I usually run out of bandwidth before it goes near 3-5% cpu usage.
- Shared Cache - Can be used as a general cache for all users of a computer/network instead of one cache per profile.
- Automatic config - Auto generates the .pac file for automatic proxy settings, no more updating in the do not use proxy section of individual users browsers.
- Anonymous P2P proxy - Joining the anonymous proxy network will allow you to use other peoples proxys for browsing and allow them to use yours.
- SOCKS - Supports enough of SOCKS to run ftp, most Instant messengers, irc, limewire, etc.
- User authentication - Supports external user authentication.
Enhancements:
- The program now checks for errors in access configuration.
- Variable timeout values were added.
- Log rotation was fixed.
- Occasional crashes on a bad URL were fixed.
- The auto configuration .pac file was fixed, so it should work even if the proxys URL was not set properly.
- Anon proxy defaults to 3 keys now for more reliability.

HTTP Proxy Client is the small set of libraries and scripts, which provides transparent access to Internet via HTTP proxy for programs, which uses TCP/IP for communication.
The list of programs includes: telnet, ftp, licq, cvs, smth else? Project implements dynamic library, that can be preloaded before program run.
The library substitutes some system calls (connect(), gethostbyaddr(), gethostbyname()), with calls, which makes TCP/IP connection through HTTP proxy. This allows client programs behind HTTP proxy work with Internet without limitations.
At the moment tested on i386 Linux, i386/sparc Solaris.
Enhancements:
- While using dotted address, applications will attempt to connect regardless DNS lookup result.

Mobile Web Proxy is a (CGI) tool to make more Web pages available from some mobile devices (cell phone Web browsers, etc.).
When I began using my cell phones mobile web browser, one of the things I realized was that there were a lot of web pages that my cell phones web browser simply wouldnt let me see. My shiny new Motorola Razr from T-Mobile, for many pages, would display an error message like "413: Page cannot be displayed." It happened annoyingly often; browsing the web from my cell phone was a lot like trying to read a book or a magazine with large chunks simply ripped out. And when I tried troubleshooting, I might have missed something, but it seemed like a big problem without an easily available solution.
So I tried to provide my own solution. I made a proxy that would present webpages for the mobile web so that they would display in a way that would work for my cell phones web browser. Technologies include paging, tag cleaning, and optional caching to improve performance, but without getting into technical details, this means that I can access some pages on the web that I couldnt access earlier.
Enhancements:
- A bug that caused the script to spuriously report 404 errors was fixed.
- A smaller default page size was set so that tag-rich pages would be rendered in a way more likely to be displayable on mobile Web browsers.

IMAP Proxy server is a caching IMAP proxy server. It was written to compensate for webmail clients that are unable to maintain persistent connections to an IMAP server. Most webmail clients need to log in to an IMAP server for nearly every single transaction.

This behaviour can cause tragic performance problems on the IMAP server. imapproxy tries to deal with this problem by leaving server connections open for a short time after a webmail client logs out.

When the webmail client connects again, imapproxy will determine if theres a cached connection available and reuse it if possible.

How does imapproxy keep track of which server connection is for which user?

Upon the first successful login to the real IMAP server (through the proxy), imapproxy fills in a little record that contains the username, an md5 digital signature of the password and the server socket descriptor thats being used.

After you log out and then log back in again, imapproxy just has to find a record that matches your username and password. These records are stored in a hash table (with the username being the hash key) in memory, so the lookups are pretty fast.

Can IMAP Proxy support multiple backend servers?

If you want IMAP Proxy to be able to proxy to multiple backend IMAP servers, you can run multiple instances of IMAP Proxy and make sure each instance is looking at a different configuration file.

Before you do this, take a look at perdition which appears to have been designed with this specific task in mind.

Spike Proxy is an open source HTTP proxy for finding security flaws in web sites.

SPIKE Proxy is part of the Spike Application Testing Suite and supports automated SQL injection detection, web site crawling, login form brute forcing, overflow detection, and directory traversal detection.

To Use:

python spkproxy.py [ optional port argument, 8080 is default ]
Then set up your browser to use that port for both HTTP and
HTTPS proxies.

Then watch the traffic go!

Frickin PPTP Proxy is a fast PPTP proxy for any BSD system with the OpenBSD packet filter installed.
It handles bi-directional tunnels transparently and can be chained from one proxy to another over several servers.
Enhancements:
- This release fixes an endian issue with echo IDs that made the proxy unusable for a majority of users.
- There is additional information regarding a pf scrub issue in the documentation.
