Only several hundreds of passwords per second.

Besides, the key derivation function uses more than 70000 SHA-1 transformations and brute force rate on modern CPU is very low, Starting from version 3.0, RAR has been using a strong AES algorithm, which also doesn't allow any attacks more effective At least no RAR 2.0 attacks were known except brute force for password recovery. RAR/WinRAR archiver version 2.x used its proprietary, but rather strong encryption algorithm. Password length is limited to 28 symbols.No multi-core support, only one CPU or GPU is used.Limitations of cRARk (comparing to Parallel Password Recovery):

Portability (Windows, Linux, Mac OS versions are available).Unique PDL language which is extremely efficient if user remembers any information about a forgotten passwordĪny (European) language support with native Unicode implementation.Multi-volume, self-extracting, encrypted header archives support.Support of GPU password recovery on NVIDIA and AMD GPUs using CUDA and OpenCL technologies.One of the fastest RAR password recovery software, with the optimization for latest x86 instructions: AVX2, AVX, XOP, AES-NI, SHA extensions for Intel and AMD processors.All RAR versions support, including the latest RAR 5.x.Password (longer than 6-7 symbols) if you have no additionalĬRARk is the professional tool, it uses command-line interface, has no GUI.ĬRARk is the freeware utility for Win32/64, Linux, Mac OS. Please bear in mind you have quite no chance to crack unknown recover your forgotten password on RAR archives.Īny Rar/WinRar versions 2.x-5.x are supported.

Perhaps if you include the entire set of instructions and the underlying goal, i.e. It sounds like, from the instructions you were given, they weren't quite clear on exactly what was meant by 'overwrite resource folder with mdm.dat' as, typically, this would be called renaming a directory. Sample command from Terminal: cp ~/Desktop/file.sh /Users/username/folder1 Note: If you aren't familliar with Unix commands, it's highly adviseable that you stay clear of Terminal as you can cause your system to not boot. Finder->Applications->Utilities->Terminal. You can also use the Terminal to do it a bit more 'manually'. Meaning, if you click and drag a file/folder onto an icon such as your hard drive, namely 'Macintosh HD', and hold it there for a couple of seconds, Finder automatically opens and allows you to drag into directories and sub-directories.

Well, by default, Snow Leopard has something called spring-loaded icons.
