 cryptlib  License: Freeware

 
  Cryptlib by Peter Gutmann is a security toolkit that allows even less experienced programmers to add strong encryption and authentication services to their programs, security features that are becoming more and more indispensable. The library attempts to hide the low-level details of encryption/decryption and authentication from programmers, allowing them to quickly make their projects more secure. Some of the symmetric encryption (private key) and authentication algorithms that cryptlib supports include the following: · AES (Rijndael) · Blowfish · DES, 3DES · RC2, RC4, RC5 The following hash algorithms are available in the library: · MD2, MD4, MD5 · RIPEMD-160 · SHA It offers services such as: · S/MIME · SSL/TLS · ssh It features various hashed message authentication code algorithms: · HMAC-MD5, HMAC-SHA, HMAC-RIPEMD-160 Finally, asymmetric (public/private key) encryption algorithms such as the following are available: · Diffie-Hellman, DSA, RSA cryptlib can also be used with a variety of crypto devices (for example, Fortezza cards and Smart cards). The library is free if used in personal, freeware, or shareware projects. The library is written in C. ActiveX and C++ wrappers are provided. The project is OSI Certified Open Source Software.

 OpenSSL  License: Freeware

 
  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.

 RF21  License: Freeware

 
  RF21 for Windows is a scientific calculator, plotter, programming and numeric system in one. It allows for permanent installation of a user's own commented functions and libraries. Such user functions may have one or several arguments and values. Works as an archive at the same time, with integrated searchable database, to let you find and reuse materials created years ago. Each function self-reassembles when its name is called, autonomously searching the libraries for all components needed. Predefined functions include gamma, zeta, psi and Bessel functions, error integral, cumulative Binomial distribution and more. On top of these and the user libraries, the program's numeric and plotting capabilities can be used, including: Numeric derivation and integration, Monte Carlo simulations, linear equations, matrix inversion and eigenvalues, nonlinear equation systems, n-dimensional function minimizer (Dennis & Schnabel method), Runge Kutta method for (systems of) differential equations, accelerated summation of series. Fraction reckognizer. Fast screenplots and an environment for designing printable plots, which may as well be exported to -.GIF and -.BMP files. Ample support for both simple and parametric plots, composition of several curves into one picture, drawing of directional or vector fields. Comes with standard libraries covering areas of science and mathematics. Some 200 standard functions, see author's homepage for a systematic reference of these.

 Olvio.Ecommerce for Authorize.Net  License: Freeware

 
  Olvio.Ecommerce is a payment processing class library for the Authorize.Net payment gateway. It includes all the latest features, SIM and AIM integration methods, CC and ECHECK processing, hash validation, response stream reader and more. Includes a SimResponseReader class to handle the silent posting from a SIM transaction. It can validate and process transactions for the Wells Fargo merchants. Fully written in C# it offers a strong object model with powerful exception handling that allows the merchant to validate data before sending it to the gateway. The class library automatically reads and parses the gateway response and validates the MD5 hash to assure that the response is authentic. Includes also a SNTP class that is able to connect to an internet time server and get the real time for a certain zone to be used in connection with the SIM integration method.
