Stegdetect is an automated tool for detecting steganographic content in images. It is capable of detecting several different steganographic methods to embed hidden information in JPEG images. Currently, the detectable schemes are: * jsteg * jphide (Unix and Windows) * invisible secrets * outguess 01.3b * F5 * appendX and camouflage

MED stands for "Mod�lisation et �changes de Donn�es", i.e. Data Modelization and Exchanges. MED ��fichier��, c'est�: * Un mod�le d'�change de donn�es commun centr� sur les notions de maillage et de r�sultat. Ce mod�le d�crit quelles sont les donn�es export�es et �chang�es entre les codes. * Une API (Application Programming Interface) d'acc�s aux donn�es qui se pr�sente sous la forme d'une biblioth�que informatique �crite en C et FORTRAN 77. Cette biblioth�que est distribu�e sous licence GNU LGPL. * Des donn�es �chang�es et stock�es dans des fichiers au format HDF (Hierarchical Data Format).

This plugin allows you to write e.g. shopping cart code which should behave well for guests as well as permanent users. The basic idea is both logged in and not logged in users can get the same benefits from sessions where it doesn't matter, but that logged in users can keep their sessions accross logins, and will even get the data they added/changed assimilated to their permanent account if they made the changes as guests and then logged in. This is probably most useful for e-commerce sites, where the shopping cart is typically used before login, and should be equally accessible to both guests and logged in users.

s11n (an abbreviation for serialization) is an Open Source project focused on the generic serialization of objects (i.e., object persistence) in the C++ programming language. The project's flagship library, appropriately named libs11n, can easily serialize all manner of PODs (Plain Old Data types), most STL containers, and user-defined Serializable types. By taking advantage of relatively new, advanced C++ techniques s11n turns this formerly-difficult task into child's play. It supports literally hundreds of millions of combinations of standard containers out of the box. libs11n is 100% data-format agnostic, and currently includes support for many formats, including 3 XML flavours. (As far as i am aware, this exceeds support provided by any other serialization framework, regardless of the implementation language!)

This is a port of btoa version 5.2, written by Paul Rutter, Joe Orost & Stefan Parmark. btoa converts 4 binary characters to 5 ascii ones, causing a 25% expansion. (btoa is thus more efficient than uuencode, which causes a 33% expansion.) Spaces will not be used, which should make it safe to send files over e-mail or Usenet without risking that blanks become tabs. Each resulting row of text has a single-byte checksum for error detection. A diagnosis file provides a list of errors found this way, which could then be used to retransmit only the failing lines. Patch 1 is an unofficial, non-platform-specific patch to version 5.2 of btoa. It allows for automatic decoding of btoa files if the program is invoked as "atob" (no -a argument necessary). It also outfits the Makefile to do clean and install.

The Storable package brings you persistency for your perl data structures containing SCALAR, ARRAY, HASH or REF objects, i.e. anything that can be conveniently stored to disk and retrieved at a later time. It can be used in the regular procedural way by calling store with a reference to the object to store, and providing a file name. The routine returns undef for I/O problems or other internal error, a true value otherwise. Serious errors are propagated as a die exception. To retrieve data stored to disk, you use retrieve with a file name, and the objects stored into that file are recreated into memory for you, and a reference to the root object is returned. In case an I/O error occurred while reading, undef is returned instead. Other serious errors are propagated via die.

SWF Tools is a collection of SWF manipulation and generation utilities At the moment, this includes: - PDF2SWF : A PDF to SWF Converter. Generates one frame per page. - SWFCombine : A tool for inserting SWFs into Wrapper SWFs. - SWFStrings : Scans SWFs for text data. - SWFDump : Prints out various informations about SWFs. - JPEG2SWF : Takes one or more JPEG pictures and generates a SWF slideshow. - PNG2SWF : Like JPEG2SWF, only for PNGs. - GIF2SWF : Converts GIFs to SWF. Also able to handle animated gifs. - WAV2SWF : Converts WAV audio files to SWFs with MP3 Streams, using the L.A.M.E. MP3 encoder. - Font2SWF : Converts font files (TTF, Type1) to SWF. - SWFBBox : Allows to readjust SWF bounding boxes. - SWFC : A tool for creating SWF files from simple script files. - SWFExtract : Allows to extract Movieclips, Sounds, Images etc. from SWF files. - AS3Compile : A standalone ActionScript 3.0 compiler. Mostly compatible with Flex.

Courier is a modular multiprotocol mail server that's designed to strike a balance between reasonable performance, flexibility and features: * Can be configured to function as an intermediate mail relay, or as a mail server that receives mail for one or more domains, or anything in between. * Web-based administration and configuration tool. * Uses an efficient maildir format as its native mail storage format. Some support is provided for legacy mbox mailboxes. * STARTTLS ESMTP extension (as well as IMAP/POP3/Webmail over SSL) in both the client and the server (requires OpenSSL). The ESMTP client can optionally require that the remote server's X.509 certificate is signed by a trusted root CA (a default set of root CAs is provided). * Mailboxes can be accessed via POP3, IMAP, SMAP, and HTTP. * A faxmail gateway that forwards E-mail messages via fax. * Courier includes a mailing list manager. * PAM, LDAP, PostgreSQL, or MySQL authentication. * Authenticated SMTP. * Integrated mail filtering.

Vertex is an implementation of the Q2Q protocol (sort of like P2P, but one better). There are a few moving parts in Vertex: * PTCP: a protocol which is nearly identical to TCP, but which runs over UDP. This lets Q2Q penetrate most NAT configurations. * JUICE ([JU]ice [I]s [C]oncurrent [E]vents): a very simple but immensely flexible protocol which forms the basis of the high-level aspects of Q2Q * vertex: a command line tool which exposes a few features useful in many situations (such as registration and authentication) The Q2Q network has some decentralized features (there is no one server or company which can control all Q2Q addresses) and features of centralization (addresses beneath a particular domain are issued by a server for that domain; once issued, some activities require the server to be contacted again, while others do not). Vertex includes an identity server capable of hosting Q2Q addresses.

Tripwire is a tool that aids system administrators and users in monitoring a designated set of files for any changes. Used with system files on a regular (e.g., daily) basis, Tripwire can notify system administrators of corrupted or tampered files, so damage control measures can be taken in a timely manner. If "TRIPWIRE_FLOPPY" is set to "YES" in the environment or on the "make" command line, this port will write the tripwire database to a floppy disk, which should then be write-protected and used as a reference for future runs. The diskette should be formatted and present in the "A" drive before starting the "make install" step. Joe Greco <jgreco@ns.sol.net>
