I wonder how long it will take to crack 16 character alphanumeric WinRAR password for a mini supercomputer. As far as I know graphic cards are preferred over CPUs to crack passwords nowadays. If we consider that the cracker (law enforcment) uses the latest technologies to crack the RAR password and has pretty much computing power how long it will take for him to crack the password?
With standard GPUs breaking this would cost around $1019. Custom hardware shaves off a factor 100 or so, still giving you a cost of $1017. Even if Moore's law continues, it'll take several decades until this is remotely feasible.
Hi Blake, IAR is definitively too much expensive, I used Quadravox for a lot of time and it was better supported for an acceptable price, also competitor like rowley sell for less at a good quality but this moment CCS is lowest cost.... TI don't promote it?
I am currently using IAR demo version for educational purpose and on small code project but never I used on huge project. I Installed a 30 day demo version for MSP and ARM, licensing run on a collision also requiring XP reinstallation and a lot of time so I hate everything is requiring lock. Cracking practice drive protection to a risk of breaking also who is at right side too. I own an old beautiful CAD, it use a parallel dongle as lock, developer firm closed down, I still own a valid licence but I cannot use it due to parallel port obsolescence...
But then, there's always the option of using MSPGCC, which is quite good, free, and has a good support (Peter Bigot does his best to fix bugs asap).
It is, however, not as convenient and requires some learning. It's not a click-and-run compiler.

Chester Gillon said:The other benefit of CCS is that a single license gets you support for all CPUs from TI (with the exception of 8051 used on some radio cores), compared with IAR which requires purchasing a license for each CPU family.
475US$ can be expensive for just MSP430 but again for all set of processors from TI is a bargains. The trouble come from TI removed one of family I was using and still some issue still exist after date promised for removal on linux version :(
Resurrecting the old thread, for those of you who prefer to use the free/open-source MSP GCC compiler but also need a reliable and powerful debugging tool chain, have you tried using CCSv6? _new_in_CCSv6
This new version of CCS adds support for GCC compiler for MSP430 projects. Once downloaded from the App Store, you can create a new MSP430 GCC project, develop, compile, and debug using either GCC or CCS MSP430 compiler.
WinRAR is a trialware file archiver utility for Windows, developed by Eugene Roshal of win.rar GmbH. It can create and view archives in RAR or ZIP file formats,[6] and unpack numerous archive file formats. To enable the user to test the integrity of archives, WinRAR embeds CRC32 or BLAKE2 checksums for each file in each archive. WinRAR supports creating encrypted, multi-part and self-extracting archives.
WinRAR is a Windows-only program. An Android application called "RAR for Android" is also available.[7] Related programs include the command-line utilities "RAR" and "UNRAR"[8] and versions for macOS,[4] Linux, FreeBSD, Windows CE, and MS-DOS.
RAR/DOS started as a mix of x86 assembler and C, with the amount of assembly code decreasing over time and moving to pure C/C++ later on. The first versions of WinRAR were written in C, modern versions are using C++. RAR for Android is written as a mixture of Java and C++.[1]
WinRAR and the RAR file format have evolved over time. Support for the archive format RAR5, using the same RAR file extension as earlier versions, was added in version 5.0;[9] the older RAR file format has since been referred to as RAR4. WinRAR versions before 5.0 do not support RAR5 archives;[10] only older versions of WinRAR run on Windows versions prior to Windows Vista, and cannot open RAR5 archives.
The RAR5 file format - from version 7 on, referred to as "RAR" - increased the maximum dictionary size up to 64 GB, depending on the amount of available memory, with the default in version 5 increased from 4 MB to 32 MB, typically improving compression ratio.For dictionaries larger than 4 GB, the size can be specified if it is unequal to a power of 2. Thus, there are no restrictions to the range 4, 8, 16, 32, 64, allowing 5 GB or 22 GB to be chosen at will. Archives with dictionaries larger than 4 GB can only be extracted by WinRAR 7.0 or newer.AES encryption, when used, is in CBC mode and was increased in strength from 128- to 256-bit. Maximum path length for files in RAR and ZIP archives is increased from 2047 to 65535 characters.[10]
Options added in v5.0 include 256-bit BLAKE2 file-hashing algorithm instead of default 32-bit CRC32, duplicate file detection, NTFS hard and symbolic links, and Quick Open record to allow large archives to be opened faster.[10]
The RAR5 file format removed comments for each file (though archive comment still remains), authenticity verification, and specialized compression algorithms for text and multimedia files. RAR5 also changed the file name for split volumes from "archivename.rNN" to "archivename.partNN.rar".[10]
The RAR7 file format added support for 64GB compression dictionary and improved compression ratio by adding two extra algorithms. RAR7 archives with dictionary sizes up to 4GB can be unpacked by previous versions of WinRAR (5.0 and above) given there's enough RAM.
The software is distributed as "try before you buy"; it may be used without charge for 40 days.[2] When the period expires, the non-enterprise functionalities remain available, a move intended to discourage piracy.[5] In China, a free-to-use personal edition has been provided officially since 2015.[16]
Although archiving with the RAR format is proprietary, RARLAB supplies as copyrighted freeware the C++ source code of the current UnRAR unpacker, with a license allowing it to be used in any software, thus enabling others to produce software capable of unpacking, but not creating, RAR archives.[17]
In February 2019, a major security vulnerability in the unacev2.dll library which is used by WinRAR to decompress ACE archives was discovered.[18][19] Consequently, WinRAR dropped the support for the ACE format from version 5.70.
Self-extracting archives created with versions before 5.31 (including the executable installer of WinRAR itself) are vulnerable to DLL hijacking: they may load and use DLLs named UXTheme.dll, RichEd32.dll and RichEd20.dll if they are in the same folder as the executable file.[10][20]
It was widely reported that WinRAR v5.21 and earlier had a remote code execution (RCE) vulnerability which could allow a remote attacker to insert malicious code into a self-extracting executable (SFX) file being created by a user, "putting over 500 million users of the software at risk".[21] However, examination of the claim revealed that, while the vulnerability existed, the result was merely an SFX which delivered its payload when executed; published responses dismissed the threat, one saying "If you can find suckers who will trust a .exe labelled as self-extracting archive ... then you can trick them into running your smuggled JavaScript".[22][23]

Password cracking is one of my favorite parts of information security. Many of us have built computer systems designed specifically for this task. We use tools like John the Ripper for quickie password cracking efforts and Hashcat for larger tasks but we usually sick these tools on cryptographic password hashes we obtain from hashdumps, database tables and tools such as Responder. One of the lessons we've learned from high profile breaches such as Sony is that it's extremely common for users and organizations to also store passwords in document formats such as Microsoft Word and Excel.
