本篇文章主要介绍了”C++开源库集合 “，主要涉及到C++开源库集合 方面的内容，对于C++开源库集合 感兴趣的同学可以参考一下。

 

 

 

mimetic A free/GPL C++ MIME Library

mimetic is a free/GPL Email library (MIME) written in C++ designed to be easy to use and integrate but yet fast and efficient. It is based on the C++ standard library and heavily uses templates so require standard compliant C++ compilers. It has been developed using GCC 3.x and tested on most Unixes. mimetic code include some classes that are not strictly needed but are there just to improve performance. Most classes functionalities and behavior will be clear if you ever studied MIME and its components; if you don’t know anything about Internet messages you’ll probably want to read some RFCs to understand the topic and, therefore, easily use the library whose names, whenever possible, overlap terms adopted in the standard RFC documents. At the very least: RFC 822, RFC 2045 and RFC 2046. A more complete list can be found at the Earl Wood’s MIME page.

SNMP C++ Library, MIB Compiler and SNMP Testing Tools

These are commercial products. The SNMP Builder for C++ has two different packages, supporting Windows 2003/2000/XP operating systems:

• SNMP Builder for Microsoft VC++ v6 and .NET 2003, 2005.

• SNMP Builder for Borland C++ Builder v6 and Studio 2006.

Both SNMP Builder packages include:

• MIB Compiler.

• SNMP C++ Class Library v3.3 supporting SNMP v2c and v1.

• SNMP Sender and Tracer Utilities.

• Guide and Reference Manual.

• Examples.

The MIB Compiler with a friendly and flexible graphic user interface allows the quick and easy accomplishment of the MIB compilation process. A programmer can determine the correct order of MIBs to compile in a matter of seconds using powerful built-in error processing and file search facilities. The final step of the MIB compilation process is generation of C++ header files with MIB object definitions. The MIB Compiler enables SNMP object references to use symbolic names. This makes programming easier and simplifies the software maintenance and modification process. New, efficient, easy to use and versatile methods have been added to make software development even easier and more pleasant. As with the SNMP Toolkit, the SNMP Builder comes with two very useful SNMP tools:

• An SNMP Sender and

• An SNMP Tracer.

These two GUI utilities provide a much more precise and flexible interface (comparing to MIB browser) assisting in debugging of SNMP software and also in studying how the existing SNMP software works in real life applications. The Tracer utility replaces the need for a very expensive protocol analyzers. It can display both parsed SNMP message fields (SNMP message header, PDU fields and variable binding list details) and raw message data. The trace can be saved and printed. The utility can receive on standard SNMP ports: 161 and 162, and also on non-standard ports. The Sender utility includes a graphic editor enabling the creation of SNMP request messages with precise control of message type, header fields and variable binding list. The utility can send the requests to a specified destination, displaying the details about sent requests and received replies. The sender can send the same request multiple times to a single destination, measuring network performance and the maximum number of requests an agent can process per second. These requests can be saved and then used later on during regression testing. The detailed programming guide and reference manual in Adobe Acrobat format contains hyperlinks which simplify the quick reference look-up and serves as an on-line help. The extensive programming guide illustrates all the aspects, features and pitfalls of using class library objects, methods and properties to achieve maximum performance, reliability and flexibility of the software being developed.

It should compile on other POSIX systems using the GNU tool chain. Configuration of the JNI build via autoconf may be added somewhere down the line. There just are not enough platform-specific cases in the native code to warrant it right now, but the GNU Makefile is accumulating if blocks. The given Ping.java example program requires at least VServ TCP/IP version 0.7.x to compile because it uses the ICMPEchoPacket class. RockSaw is released under the Apache License 2.0.

Synapse project – blocking (synchronous) sockets network communication

This project deals with network communication by means of blocking (synchronous) sockets or with limited non-blocking mode. This project not using asynchronous sockets. The Project contains simple low level non-visual objects for easiest programming without problems (no need multithread synchronization, no need for windows message processing…) Great for command line utilities, visual projects, NT services… You can find more after reading about and features. This project is freeware and open source under modified BSD style license.

The SYNAPSE library aims to create a complete library of classes and functions that would markedly simplify application programming of network communication using Winsock. At first glance this effort might seem needless as there are many free components covering this area, however they mostly use asynchronous methods while SYNAPSE library operates in a synchronous method.

Synchronous mode (called ‘blocking’ in Winsock terminology) features acting thread waits until the needed operation terminates. Thus when we want to send data, the program exits function only after data is sent – or – if we want to receive data, the program exits the function only after the desired data is received. Thus, much more crisp and simple programming is achieved. You will feel it when trying to implement any Internet protocol, which is typically based on ‘send-wait for reply’ method. If you want to implement it in an asynchronous method, you would have to accept complicated event processing and synchronous mode simulation. Therefore a synchronous socket is simple and natural for the majority programming tasks. The whole library is oriented on the WIN32 environment or Linux environment, so you will need Delphi 3.0 or higher and Kylix 1.0 or higher to use it

Sound Processing Kit (abbreviated as SPKit) includes classes for various signal processing tasks, but most importantly, it introduces a way of implementing sound processing algorithms in a simple object-oriented manner. Sound Processing Kit is implemented in C++.

SPKit is designed to be portable. The current version requires a bare-bones C++ 2.0 compatible compiler (templates and exceptions are not needed). ANSI C standard libraries are required. The source code should compile with little or no modification on most UNIX compatible platforms.

There are three versions of the SPKit class library: a “generic” version, a libaudiofile version, and an SGI version. The generic version is the most portable one and does not require extra libraries audio file I/O. On the other hand, the number of supported sound file formats is very limited. The libaudiofile version requires the Audio File Library system for file I/O. Audio File Library is with many Linux distributions and has been ported to other operating systems as well. The home page of Audio File Library is at audio files. The SGI version is written specifically for the SGI/IRIX system.

The main target applications for GMP are cryptography applications and research, Internet security applications, algebra systems, computational algebra research, etc. GMP is carefully designed to be as fast as possible, both for small operands and for huge operands. The speed is achieved by using full words as the basic arithmetic type, by using fast algorithms, with highly optimized assembly code for the most common inner loops for a lot of CPUs, and by a general emphasis on speed. GMP is faster than any other bignum library. The advantage for GMP increases with the operand sizes for many operations, since GMP uses asymptotically faster algorithms. The first GMP release was made in 1991. It is continually developed and maintained, with a new release about once a year. GMP is distributed under the GNU LGPL. This license makes the library free to use, share, and improve, and allows you to pass on the result. The license gives freedoms, but also sets firm restrictions on the use with non-free programs. GMP is part of the GNU project…”

MIRACL – Multiprecision Integer and Rational Arithmetic C/C++ Library

MIRACL – Multiprecision Integer and Rational Arithmetic C/C++ Library is a Big Number Library which implements all of the primitives necessary to design Big Number Cryptography into your real-world application. It is primarily a tool for cryptographic system implementers. RSA public key cryptography, Diffie-Hellman Key exchange, DSA digital signature, they are all just a few procedure calls away. Support is also included for even more esoteric Elliptic Curves and Lucas function based schemes. The latest version offers full support for Elliptic Curve Cryptography over GF(p) and GF(2m). Less well-known techniques can also be implemented as MIRACL allows you to work directly and efficiently with the big numbers that are the building blocks of number-theoretic cryptography. Although implemented as a C library, a well-thought out C++ wrapper is provided, which greatly simplifies program development. Most example programs (25+ of them) are provided in both C and C++ versions. The latest version also implements the new Advanced Encryption Standard (AES), Modes of Operation, and the new hashing standards SHA-160/256/384/512. MIRACL is compact, fast and efficient and easier than ever to get the same near-optimal performance from any processor. Although essentially a portable library, inline assembly and special techniques can be invoked for blistering speed. MIRACL has also been successfully used in both embedded and DSP environments where space is at a premium. A new special purpose macro assembler feature facilitates the achievement of best possible performance from your embedded processor (embedded – .doc document). MIRACL is, to an extent, self-configuring. Use your compiler to compile and run a simple configuration program, which proceeds with user interaction to generate optimal settings for your environment. Unlike other Cryptographic libraries, MIRACL does not merely provide an opaque interface to a predetermined set of Cryptographic methods, but rather a set of tools that enable any new number-theoretic technique to be implemented quickly, so that the end-user is, for example, free to design their own Cryptographic API. It is particularly appropriate (and free) for educational use.

ADOL-C

The package ADOL-C facilitates the evaluation of first and higher derivatives of vector functions that are defined by computer programs written in C or C++. The resulting derivative evaluation routines may be called from C/C++, Fortran, or any other language that can be linked with C. The numerical values of derivative vectors are obtained free of truncation errors at a small multiple of the run time and randomly accessed memory of the given function evaluation program. ADOL-C is available free of charge provided under the terms of the Common Public License

LiDIA is a C++ library for computational number theory which provides a collection of highly optimized implementations of various multiprecision data types and time-intensive algorithms. LiDIA is developed by the LiDIA Group at the Darmstadt University of Technology. LiDIA is free for non-commercial purposes (license) and comes with the full source code. The current release of LiDIA contains the following components:

• Arithmetic Interfaces to cln, gmp, libI, piologie.

• Basic arithmetic over Z, Q, R, C, interval arithmetic, GF(2n), GF(pn).

• Factorization: Integer Factorization (Trial Division, Elliptic Curve Method, Self-Initializing Multipolynomial Quadratic Sieve with Lanczos algorithm), Factorization of Polynomials over finite fields (V. Shoup’s algorithms), Factoring ideals of algebraic number fields.

• Lattice Basis Reduction: various versions of LLL/MLLL (Schnorr-Euchner, Benne de Weger).

• Linear Algebra over Z: basic operations, normal forms of matrices (G. Havas algorithms)
  Number Fields: Quadratic Number Fields including a new implementation of Buchmann’s sub exponential algorithm for computing classgroups using mpqs techniques, Higher-Degree Number Fields arithmetic and maximal order.

• Polynomials: template classes for univariate polynomials with special algorithms for different domains.

• Elliptic Curves: elliptic curves over the rational and over finite fields (includes code written by J.Cremona and N. Smart). There is also a package for counting points on elliptic curves as well as a package for generating cryptographically strong curves.

• Primality Proofing: Besides the standard probabilistic primality tests in the base package there is a new elliptic curve based primality proofer in the GEC package.
