    Thread: Salt input and bruteforcing
Post: RE: Salt input and bruteforcing

is the "number(1 to 9).1234567890876543" part fixed? If so you should add it to the salt. You don't need to define ?1 for a single character. You can simply use that character in the mask.

If you care only for a single hash/list of hashes you can quickly write a wrapper script. Otherwise, no, not possible.

if your cost factor is 4 (note: bcrypt does not have a iteration/round indicator) your prefix is probably $2y$4

32 byte salt is impossible to brute-force, assuming that means 32*8 bits. A little less would still be impossible to brute-force (ie 32*7). All other security properties are trivially fulfilled under...

If you want to resume an attack you should use the session restore feature or the brain server.

afaik you get an unrestricted usage license as long as you're a Sagitta HPC customer. But it's certainly something you should ask their sales department about directly.

Post: RE: Some way to 'increment from a wordlist'

You can use princeprocessor for this. It can handle everything but the space between the words. Toggling the case of the first character can be done with a hashcat rule.

Post: RE: Some way to 'increment from a wordlist'

Yes, you could simply append a space to every word in your wordlist for that case. Just remember to add a rule in hashcat that deletes the trailing space of the last word.
