    Thread: Cisco IOS MD5 BruteForce Mask
Post: RE: Cisco IOS MD5 BruteForce Mask

This looks normal. Brute force automatically starts with short masks and then moves on to longer ones. While it's moving through the short masks, they're too short to really make the GPUs work hard, ...

    Thread: How Calculate GPU Cracking Time
Post: RE: How Calculate GPU Cracking Time

The best way to do this is to perform an actual run. Raw wordlist mode (with no rules) is very, very fast. hashcat's guessing speed is so fast that it can often spend more time caching a large dict...

Have you looked into hashcat's rules and masks? You may be able to significantly reduced the size of your wordlist, in exchange for faster coverage of your likely password space. For example, if your...

    Thread: blowfish brute
Post: RE: blowfish brute

Just as descrypt (-m 1500) is based on DES (but is much more, because it adds rounds/stretching/etc.), and md5crypt (-m 500) is similarly derived from MD5, it is the bcrypt hash (-m 3200) that is buil...

An artificial hash is fine. The $2a$ format is indeed blowfish-based bcrypt. Can you post the full command line you're using?

Yeah, it sounds like you need a mode that I don't think hashcat currently supports: md5(md5($salt).md5($pass)) You could then format your hashes as [hash]:[username], and use the username as the...

I haven't tried it, but MDXfind might support it? It lists "MD5-MD5SALTMD5PASS". MDXfind supports CPU.
