It's C. Try compiling it on a Linux system.

Note also the compilation instructions that are in the source code itself: cc -o md5substr md5substr.c -march=native -O3 -funroll-loops -fomit-frame-pointer -pthread

Probably possible, but I have no experience in that area. Someone else may be able to chime in.

    Thread: NTLM: hashcat vs RainbowCrack
Post: RE: NTLM: hashcat vs RainbowCrack

It depends. This boils down to the time/memory tradeoff. I'll lay out some of the concepts. Most real-world passwords are of sufficiently low quality that if they are stored poorly (unsalted/fast h...

Post: RE: NTLM: hashcat vs RainbowCrack

OK, that makes sense. So as soon as you have more than two or three hashes, hashcat will be faster even for limited bruteforce criteria that I listed.

That looks about right, then. I get the same 50%-ish drop when I do 40 NTLM: $ hashcat -b -m 1000 hashcat (v3.30) starting in benchmark mode... OpenCL Platform #1: NVIDIA Corporation =========...

See the ./charsets/ subdirectory for character sets that you can use. If you don't know what the target languages might be, apply some wordlists first to determine language frequency, and then target ...

Ah, I was reading too quickly - if you're especially interested in multibyte, the stock charsets won't help, but Rurapenthe's post about bruteforcing should still be helpful. The essential insight is ...

Huh - yeah, I went back through my notes/scripts and all the iconv items were just -f [source-format] -t [dest-format]. I thought it was harder than that, but I guess not!
