Symmetric Key Software

The Matrix ActiveX Component simplifies the use of matrix operations in application development. It provides for matrix operations such as addition, subtraction, multiplication, inversion, transpose, computation of determinant, LU and Cholesky decompositions. Advanced edition additionally supports QR and Singular Value (SVD) decompositions, Eigenvalue and Eigenvector computation for symmetric and non symmetric real or complex matrices.

Puffer is a general purpose 256-bit AES encryption utility for protecting your most sensitive data. Use Puffer to securely exchange email with other Puffer users via the 2048-bit Diffie-Hellman key exchange function. Compress and encrypt your data files into zip-style PUF archives. Use steganography to hide data among the pixels of image files. Distribute self-decrypting archives to non-Puffer users. Permanently erase data with wipe functions.

SmartEncryptor uses the most powerfull encryption algorythms existing. AES - the US Government standard symmetric encryption algorythm and Blowfish. Works on all Windows systems.

PDFBlackbox.NET is a comprehensive collection of managed components that help you compress, encrypt and sign PDF documents from your .NET Framework applications. Both symmetric and certificate-based (X.509) encryption and signing is supported. .NET edition can be used with MS Visual Studio 2003, Borland Delphi 8 and 2005, C# Builder.

PDFBlackbox (VCL Edition) is a comprehensive collection of native components that help you compress, encrypt and sign PDF documents from your Delphi or Kylix applications. Both symmetric and certificate-based (X.509) encryption and signing is supported. VCL edition can be used with Delphi 4-7 and 2005, C++Builder 4-6 and Kylix 2-3.

BMDFM (Binary Modular DataFlow Machine) is software, which enables running an application in parallel on shared memory symmetric multiprocessors (SMP) using the multiple processors to speed up the execution of single applications. BMDFM automatically identifies and exploits parallelism due to the static and mainly DYNAMIC SCHEDULING of the data flow instruction sequences derived from the formerly sequential program.

A security toolkit letting even less experienced programmers add encryption and authentication services to their apps, features that are becoming indispensable. The library hides low-level details of security from developers. It supports a variety of algorithms for symmetric/asymmetric encryption, authentication, and hashing. The library is free for non-commercial/shareware projects. It is written in C. ActiveX and C++ wrappers are available.

Amelix FCP allows for the power encryption and decryption of all your personal files. Encrypt and decrypt files of any type. This is symmetric-key cryptography program. Amelix File Cryptor Pro does not change a size and date of encoded files. If the user enters wrong key, the encrypted file will be decoded but it's content will be invalid. Amelix FCP has a unique powerful algorithm that gives maximum password protection from breaking in.

This program serves to encrypt texts (for example emails). It is based on symmetric encryption. The following keys can be used to encrypt texts: *Codewords, *Key disks,*Key files (any desired files can serve as keys). Key disks or Key files can be created by the program.

Colored pieces are laid out on a game field. They form a symmetric pattern. After the beginning of party the pieces mix up chaotically. Your task to get a initial pattern. You can move a row or a column only. Any line of pieces are closed in a ring. It means, the pieces, getting out of a game field, will appear on the opposite side. Using 'Editor', you can create any patterns.
