IDA (or the Interactive DisAssembler) is a disassembler for computer software which generates assembly language source code from machine-executable code. It supports a variety of executable formats for different processors and operating systems. It also can be used as a debugger for Windows PE, Mac OS X Mach-O, and Linux ELF executables. A decompiler plug-in for programs compiled with a C/ compiler is available at extra cost. The latest full version of IDA Pro is commercial; while an earlier and less capable version is available for download free of charge (version 5.0 ).〔(IDA Pro 5.0 Freeware version download )〕 IDA performs automatic code analysis, using cross-references between code sections, knowledge of parameters of API calls, and other information. However, the nature of disassembly precludes total accuracy, and a great deal of human intervention is necessarily required; IDA has interactive functionality to aid in improving the disassembly. A typical IDA user will begin with an automatically generated disassembly listing and then convert sections from code to data and vice versa, rename, annotate, and otherwise add information to the listing, until it becomes clear what it does. Created as a shareware application by Ilfak Guilfanov, IDA was later sold as a commercial product by DataRescue, a Belgian company, who improved it and sold it under the name IDA Pro. In 2005, Guilfanov founded Hex-Rays to pursue the development of the Hex-Rays Decompiler IDA extension. In January 2008, Hex-Rays assumed the development and support of DataRescue's IDA Pro. ==Scripting== "IDC scripts" make it possible to extend the operation of the disassembler. Some helpful scripts are provided, which can serve as the basis for user written scripts. Most frequently scripts are used for extra modification of the generated code. For example, external symbol tables can be loaded thereby using the function names of the original source code. There are websites devoted to IDA scripts and offer assistance for frequently arising problems. Users have created plugins that allow other common scripting languages to be used instead of, or in addition to, IDC. (IdaRUB ) supports Ruby and (IDAPython ) adds support for Python. As of version 5.4, IDAPython (dependent on Python 2.5) comes preinstalled with IDA Pro. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Interactive Disassembler」の詳細全文を読む スポンサード リンク
