Distributed RSA Key Generation 1.0
Distributed RSA Key Generation is a software to generate shared RSA keys. more>>
Distributed RSA Key Generation is a software to generate shared RSA keys. Currently, only keys for two parties using Gilboas protocol are supported. But the protocol stack is extensible, so in the future there may be other protocols supported.
Work has begun on Straubs protocol but is not finished yet, multi-party protocols like Boneh-Franklins may also be added in the far future.

yyyRSA 1.0.2
yyyRSA is a simple program to encrypt and decipher messages with the RSA asymetrical encryption algorithm. more>>
yyyRSA is a simple program to encrypt and decipher messages with the RSA asymetrical encryption algorithm.
Alice wants to send Bob a message. Eve can monitor the communication between Alice and Bob. he can read everything they send to each other.
Bob creates a key. It will consist of two files. the public key and the private key.
Bob gives Alice his public key.
Eve now also has his public key!
Alice encrypts a message with this public key.
Alice sends the message to Bob
Eve now also has the encrypted message!
Bob decrypts the message with the secret key.
Eve can do nothing, because it is not possible to decrypt the message with the public key !
yyyRSA is designed to be ULTRA secure. speed doesnt matter, nor does size of the encrypted message.
It is a possible option to create the secret key if you have a public key. However the algorithm to do this takes too much time, see the next chapter.
Enhancements:
- Added numberencode program
- Released 1.0.2

Eureka Public Key 1.0.0
Eureka Public Key was created due to numerous requests for a public key application using our strong encryption techniques. more>>
Eureka Public Key was created due to numerous requests for a public key application using our strong encryption techniques. The basic principle for its use is one creates their own public key and distributes the key to whomever they will be transferring encrypted files with.
When one receives a key, they import it into their key database. You can create and import as many keys as you wish. Both public keys are used in the cryption process. You select your particular public key to use and the public key of the person who will receive it.
When a file has been received you put in your public key that matches the one they used and select their public key that was used in the encryption. See the Encryption, Decryption and Import/Export sections for more information on these topics. To create a public key, click on Keys then Create Public Key or click on the gold key icon under the menu items.
All you have to do is define a name for the public key and click on Create. All encrypted files will be written to the Encryptions folder. Likewise, all decrypted files will go to the Decryptions folder. If a file already exists with the same name, it will be overwritten.
Encryption:
To Encrypt a file, click on File then Encrypt.
All you have to do is select Your public key, their public key and click on Encrypt or press enter then select the file you want to process.
The file selected will be encrypted and then placed in your Encryptions folder. Now you can send this file in the manner you prefer.
Note that this application encrypts in a binary format. In other words, it uses the full 256 character set and is not a text file. You will need to send it as an attachment if you are using email to transmit it.
Decryption:
To Decrypt a file, click on File then Decrypt.
All you have to do is select Your public key, their public key then click on Decrypt and select the file you want to process.
The file selected will be decrypted and then placed in your Decryptions folder.

Sort::Key 1.28
Sort::Key is the fastest way to sort anything in Perl. more>>
Sort::Key is the fastest way to sort anything in Perl.
SYNOPSIS
use Sort::Key qw(keysort nkeysort ikeysort);
@by_name = keysort { "$_->{surname} $_->{name}" } @people;
# sorting by a numeric key:
@by_age = nkeysort { $_->{age} } @people;
# sorting by a numeric integer key:
@by_sons = ikeysort { $_->{sons} } @people;
Sort::Key provides a set of functions to sort lists of values by some calculated key value.
It is faster (usually much faster) and uses less memory than other alternatives implemented around perl sort function (ST, GRT, etc.).
Multikey sorting functionality is also provided via the companion modules Sort::Key::Multi, Sort::Key::Maker and Sort::Key::Register.
FUNCTIONS
This module provides a large number of sorting subroutines but they are all variations off the keysort one:
@sorted = keysort { CALC_KEY($_) } @data
that is conceptually equivalent to
@sorted = sort { CALC_KEY($a) cmp CALC_KEY($b) } @data
and where CALC_KEY($_) can be any expresion to extract the key value from $_ (not only a subroutine call).
For instance, some variations are nkeysort that performs a numeric comparison, rkeysort that orders the data in descending order, ikeysort and ukeysort that are optimized versions of nkeysort that can be used when the keys are integers or unsigned integers respectively, etc.
Also, inplace versions of the sorters are provided. For instance
keysort_inplace { CALC_KEY($_) } @data
that is equivalent to
@data = keysort { CALC_KEY($_) } @data
but being (a bit) faster and using less memory.
The full list of subroutines that can be imported from this module follows:
keysort { CALC_KEY } @array
returns the elements on @array sorted by the key calculated applying { CALC_KEY } to them.
Inside { CALC_KEY }, the object is available as $_.
For example:
@a=({name=>john, surname=>smith}, {name=>paul, surname=>belvedere});
@by_name=keysort {$_->{name}} @a;
This function honours the use locale pragma.
nkeysort { CALC_KEY } @array
similar to keysort but compares the keys numerically instead of as strings.
This function honours the use integer pragma, i.e.:
use integer;
my @s=(2.4, 2.0, 1.6, 1.2, 0.8);
my @ns = nkeysort { $_ } @s;
print "@nsn"
prints
0.8 1.6 1.2 2.4 2
rnkeysort { CALC_KEY } @array
works as nkeysort, comparing keys in reverse (or descending) numerical order.
ikeysort { CALC_KEY } @array
works as keysort but compares the keys as integers (32 bits or more, no checking is performed for overflows).
rikeysort { CALC_KEY } @array
works as ikeysort, but in reverse (or descending) order.
ukeysort { CALC_KEY } @array
works as keysort but compares the keys as unsigned integers (32 bits or more).
For instance, it can be used to efficiently sort IP4 addresses:
my @data = qw(1.2.3.4 4.3.2.1 11.1.111.1 222.12.1.34
0.0.0.0 255.255.255.0) 127.0.0.1);
my @sorted = ukeysort {
my @a = split /./;
(((($a[0] name,
$_->middlename },
qw(str str str);
Sort::Key::register_type Color =>
sub { $_->R, $_->G, $_->B },
qw(int int int);
Once a datatype has been registered it can be used in the same way as types supported natively, even for defining new types, i.e.:
Sort::Key::register_type Family =>
sub { $_->man, $_->woman },
qw(Person Person);
<<lessSYNOPSIS

Berkeley DB includes b+tree, queue, extended linear hashing, fixed, and variable-length record access methods, transactions, locking, logging, shared memory caching, database recovery, and replication for highly available systems.
Berkeley DB delivers the core data management functionality, power, scalability and flexibility of enterprise relational databases but without the overhead of a query processing layer. Combined with the stability and lower support cost of open source code, Berkeley DB offers many advantages
DB supports C, C++, Java, PHP, and Perl APIs. It is available for a wide variety of UNIX platforms as well as Windows XP, Windows NT, and Windows 95 (MSVC 6 and 7).
Sleepycat Software makes Berkeley DB, the most widely used open source developer database in the world with over 200 million deployments. Customers such as Amazon.com, AOL, British Telecom, Cisco Systems, EMC, Google, Hitachi, HP, Motorola, RSA Security, Sun Microsystems, TIBCO and VERITAS also rely on Berkeley DB for fast, scalable, reliable and cost-effective data management for their mission-critical applications. Profitable since it was founded in 1996, Sleepycat is a privately held company with offices in California, Massachusetts and the United Kingdom.
Here are the advantajes of "Berkeley DB":
- Zero administration cost ? eliminates the need for a DBA;
- Smaller footprint (less than 500Kb);
- Simplicity of integration into an application;
- More speed and higher performance;
- Less complexity and more reliability.
Berkeley DB is distributed under an open source license that permits its use in open source applications at no charge. Proprietary vendors can purchase a proprietary license for Berkeley DB from Sleepycat Software.

WEP Key Changer 0.2
WEP Key Changer project, in short WepKC is a client/server application that allows you to protect your wireless network. more>>
WEP Key Changer project, in short WepKC is a client/server application that allows you to protect your ad-hoc (point to point) wireless network when you are unable to use (due to software or hardware limitations) sophisticated protocols like WPA.
The program consists out of two parts:
the wepkcd daemon, which randomly changes the WEP key after a specified amount of time and sends the chosen key, encrypted with AES, to the wepkcc client
the wepkcc client, which receives the key through the encrypted channel and changes the WEP key in the client machine
The server also waits for packets ("pings") from the client, resetting the WEP key to a defined value when the client goes down and stops pinging the server.
If someone tries to use the wireless network without contacting the server, the connection will be dropped repeatedly in order to prevent further annoyance from strangers (please note that this feature, at the moment, works only in *nix systems).
And its very easy to setup and use.

Sort::Key::Top 0.01
Sort::Key::Top is a Perl module that can select and sort top n elements. more>>
Sort::Key::Top is a Perl module that can select and sort top n elements.
SYNOPSIS
use Sort::Key::Top (nkeytop top);
# select 5 first numbers by absolute value:
@top = nkeytop { abs $_ } 5 => 1, 2, 7, 5, 5, 1, 78, 0, -2, -8, 2;
# ==> @top = (1, 2, 1, 0, -2)
# select 5 first words by lexicographic order:
@a = qw(cat fish bird leon penguin horse rat elephant squirrel dog);
@top = top 5 => @a;
# ==> @top = qw(cat fish bird elephant dog);
The functions available from this module select the top n elements from a list using several common orderings and custom key extraction procedures.
They are all variations around
keytopsort { CALC_KEY($_) } $n => @data;
This function calculates the ordering key for every element in @data using the expression inside the block. Then it selects and orders the $n elements with the lower keys when compared lexicographically.
It is equivalent to the pure Perl expression:
(sort { CALC_KEY($a) cmp CALC_KEY($b) } @data)[0 .. $n-1];
Variations allow to:
- use the own values as the ordering keys
topsort 5 => qw(a b ab t uu g h aa aac);
==> a aa aac ab b
- return the selected values in the original order
top 5 => qw(a b ab t uu g h aa aac);
==> a b ab aa aac
- use a different ordering
For instance comparing the keys as numbers, using the locale configuration or in reverse order:
rnkeytop { length $_ } 3 => qw(a ab aa aac b t uu g h);
==> ab aa aac
rnkeytopsort { length $_ } 3 => qw(a ab aa aac b t uu g h);
==> aac ab aa
A prefix is used to indicate the required ordering:
(no prefix)
lexicographical ascending order
r
lexicographical descending order
l
lexicographical ascending order obeying locale configuration
r
lexicographical descending order obeying locale configuration
n
numerical ascending order
rn
numerical descending order
i

brandgang 0.1
brandgang is a http firewall tunneling for Java applets with restricted network. more>>
brandgang is a http firewall tunneling for Java applets with restricted network.
You should install the software like this:
Extract the archive to a (home-)directory. For now there are no
installation scripts or further installation instructions.
tar -xzvf brandgang-0.1.xxx.tar.gz
WinZip users check: TAR file smart CR/LF Conversion.
You will need to create directories "var" and "lib" by hand, if your
archiver ignores empty directories. Check MANIFEST for anything
missing.
Main features:
- This transparently uses the browser configured proxy, simulating duplex communication, by multiple java.net.HttpURLConnections to a http tunnel server, that forwards the connection. Because no reference to the proxy is made, no security exceptions will be thrown for restricted applets.
-
- A combination of encryption (RSA/RC4) and message digests(MD5) is used in an effort to secure an insecure datapath. Though this comes with only a (small) telnet and SSH client, it is supposed to be easy to modify other networking applets to use tunnels.
-
- You can still use modified clients for direct connections over tcp sockets. You can also use secured connections to the tunnel server over a common tcp socket, and have the connection forwarded.
-
- The tunnel server can forward to multiple servers, handling multiple tunnels concurrently. The tunnel server can handle requests from http clients for files,
- so you dont need to run any (other) httpd to host the applets. The tunnel server can be used to enable access to a LAN. You can allow accepting and connecting hosts for the tunnel server (besides setting a Java security policy).
-
- Both server and clients are written in Java.

DVB Remote Key Editor 0.2.1
DVB Remote Key Editor project was made in order to have an easy way of modifying the keymaps of DVB-T remotes. more>>
DVB Remote Key Editor project was made in order to have an easy way of modifying the keymaps of DVB-T remotes which are usually hardcoded in the corresponding kernel-modules.
Currently this works for the following models:
Haupauge Win-TV Nova-T USB2 dvb-usb-nova-t-usb2.ko 45
Cinergy T2 cinergyT2.ko 37
AVerMedia AverTV DVB-T dvb-usb-a800.ko 34
Generic dib-usb Driver dvb-usb-dibusb-common.ko 63
WideView/Yakumo/Hama/Typhoon/Yuan DVB-T USB2 dvb-usb-dtt200u.ko 18
TwinhanDTV Alpha/MagicBoxII USB2 dvb-usb-vp7045.ko 32
This will not work if your kernel is enabled to use ksign, which secures kernel-modules against binary modifications.
Usage:
Run as root by executing: gksudo python dvb-remote-key-editor.py
Warning: This application binary patches a kernel module. Therefore be sure to make a backup of the module. THIS SOFTWARE COMES WITH ABSOLUTELY NO WARRANTY!

Entropy RSA 0.9.1-439
Entropy RSA is a a faster and more sophisticated replacement for Freenet. more>>
ENTROPY stands for Emerging Network To Reduce Orwellian Potency Yield and as such describes the main goal of the project.
Main features:
- ENTROPY is developed as a response to increasing censorship and surveillance in the internet. The program connects your computer to a network of machines which all run this software. The ENTROPY network is running parallel to the WWW and also other internet services like FTP, email, ICQ. etc.
- For the user the ENTROPY network looks like a collection of WWW pages. The difference to the WWW however is that there are no accesses to central servers. And this is why there is no site operator who could log who downloaded what and when. Every computer taking part in the ENTROPY network (every node) is at the same time server, router for other nodes, caching proxy and client for the user: that is You.
- After you gained some experience with the ENTROPY network, there are command line tools for you to insert whole directory trees into the network as a ENTROPY site. So ENTROPY does for you what a webspace provider does for you in the WWW - but without the storage and bandwidth costs and without any regulation or policy as to what kind of content you are allowed to publish. Everyone can contribute his own ENTROPY site for everybody else to browse through. The contents is stored in a distributed manner across all available and reachable nodes and no one can find out about who put up what contents into the network. Even if your node is not actively running, your contents can be retrieved by others -- without knowing that it was actually you who published the files. Of course this is only true if you do not publish your name (or leave your name or other personal data in the files you publish)
Enhancements:
- Bugfixes were made.
- This release is not backwards compatible.

OpenSSH LDAP Public Key patch 0.3.9
The OpenSSH LDAP Public Key patch provides an easy way of centralizing strong user authentication. more>>
OpenSSH LDAP Public Key patch provides an easy way of centralizing strong user authentication by using an LDAP server for retrieving public keys instead of ~/.ssh/authorized_keys.
It uses the standard core.schema/nis.schema and strongAuthenticationUser object class, which can simplify login centralization but could introduce serious security flaws if the LDAP server is not correctly configured.
Enhancements:
- A memory leak has been fixed.
- A potential LDAP filter injection if a username has strange characters in it [()*] has been fixed.
