Help for noob

Thanks for the reply, any way it's not a password, the hash algorithm is md5 and it's used as checksum, for this reason I know the text and its hash but I need to find out the salt.

So I create a file with the hash:text only and then I use the command:

hashcat -m 10 -a 3 mytexthashfile.txt

I suppose that the format is salt.pass, because I try to find the salt I have to use the reverse one, this means pass.salt mode, am I correct?
Moreover I think that the salt is just plain text with no upper case, numbers and special chars, do I have to specify a custom charset?

Thanks
