1D Stock Cutter
$120 - Astrokettle Algorithms

1D Stock Cutter is a powerful, quick, compact, easy to use and universal software tool for those users who need to optimize cutting (nesting) of any linear material: metal profiles, bars, extrusions, tubes, lineal wood, etc.

The program solves so called One-dimensional Bin Packing Problem (1DBPP) - optimizes the distribution of any number of pieces, having mostly different lengths, amongst a number of larger uniform or different stock lengths in order to minimize the material waste, or as a version - associated material cost.

Optimizer goal, as well as some technology settings, such as minimal reusable length, trim losses, piece gripping end, saw blade thickness - are adjustable. Typically, optimizer reduces stock material waste by a factor of 5 - 15 (from about 10% to about 1%) with respect to manual cut planning.

1D Stock Cutter supports network data sharing, has full data import / export capabilities via common text files (adjustable format), as well as full capabilities for printing solution reports, layout charts and piece labels in both decimal and fraction formats.

OpenSSL
$0 - ComponentSpot

By using the Open SSL 0.9.7c library, developers can write applications that take advantage of Secure Sockets Layer (SSL v2/v3), Transport Layer Security (TLS v1). The Open SSL library uses the included full-strength general-purpose cryptography library, which can be used by itself. Security features such as the following can be implemented:

· Data integrity: An application can detect if data has been modified during transmission.
· Authenticity: An application can verify the identity of the sender using certificates.
· Privacy: An application can ensure that no intermediary between the sender and the recipient can understand the data.

Transport Layer Security is an extension of SSL. It is now overseen by an international standards organization. It provides the same capabilities as SSL (data integrity, authenticity, and privacy between client and server), but takes advantage of newer, more advanced cryptographic technology. It is backwards compatible with SSL.

The cryptographic library includes a multitude of encryption algorithms. The symmetric, or private key, encryption algorithms offered include Rijndael (now officially the Advanced Encryption Standard, or AES, algorithm of the U.S. government), IDEA, DES, 3DES, RC2, RC4, and Blowfish. The asymmetric, or private/public key, encryption algorithms include RSA, DSA, and Diffie-Hellman. Also included are message digest algorithms such as MD2, MD5, MDC2, and SHA, whose resulting hashes can be used by digital signature schemes to digitally sign documents. The Open SSL library uses some but not all of these algorithms.

To compile for the Win32 platform, Perl or compiling under Cygwin is required. Some of the encryption routines/algorithms are covered by patents.

WebCab Optimization (J2EE Edition)
$249 - WebCab Components

Refined procedures for solving and performing sensitivity analysis on uni and multi dimensional, local or global optimization problems which may or may not have linear constraints. Specialized Linear programming algorithms based on the Simplex Algorithm and duality are included along with a framework for sensitivity analysis w.r.t. boundaries (duality, or direct approach), or object function coefficients.
This suite includes the following features: local unidimensional optimization; fast 'low level ' algorithms where the weight is on speed and not the accuracy of the results; bracketing algorithms - these methods find an interval where at least one extrema of a continuous function exists; locate algorithms - these methods converge to the extrema if the extrema is bracketed and the function under consideration is continuous; accurate `high level' algorithms; global unidimensional optimization - finds global minima / maxima; unconstrained local multidimensional optimization; unconstrained global multidimensional optimization; constrained optimization for derivable functions with linear constraints; linear programming - here the functions are linear and the constraints are linear; sensitivity Analysis - Stability of the value and location of the extremum
This product also contains the following feature:
GUI Bundle - we bundle a suite of graphical user interface JavaBean components allowing the developer to plug-in a wide range of GUI functionality (including charts/graphs) into their client applications.
EAR Files - we provide individual customized EAR files for the most widely used
application servers including IBM WebSphere 4.0/5.0, BEA WebLogic 6.1/7.0,
Oracle 9iAS, Sun ONE AppServer 7, Ironflare Orion 1.5.2/1.6.0, etc

CryptEnCrypt
$49.95 - iNetProm SoftLab

CryptEnCrypt is a powerful software application designed for electronic data protection. The files on your hard disk have no protection from unauthorized access. That means anyone who has access to your computer will be able to open these files and read the contents. CryptEnCrypt allows you converting your existing files to encrypted files. Encrypted files contain just the same data as before, however the encrypted data is unreadable until it is decrypted, i.e. converted to the original state. CryptEnCrypt bases data encryption on a password that you specify while encryption process. Note that there are no backdoors in this software, if you forget your password then you will not be able to decrypt data and information will be unrecoverable. CryptEnCrypt allows you to choose several encryption algorithms to protect your data. These are AES, Triple-DES, GOST, RC2, RC4 and Data Protection API based algorithms. Strong encryption ensures that your information would not be easily stolen from your computer by hackers, government, or global surveillance networks. CryptEnCrypt was developed and compiled outside of the US and is not a subject to US export restrictions.
