It'd help if you list example hashes, preferably all for a fixed password like "password", so that you don't need to list the corresponding different plaintext passwords as well. JtR supports command-line dynamic formats now (and has been for a couple of years, due to work by Jim), so most if not all of your "unsupported"s are actually supported at least in this way. Those command-line dynamics typically allow for a higher password length, too. For example, when experimenting with Update 2 from https://haveibeenpwned.com/Passwords I found that "--external=Repeats" cracks plenty of passwords of lengths up to 109 (and I've just tested that it cracks 110 too, but not 111 - as expected) with "--format=dynamic='sha1($p)'", whereas "--format=raw-sha1" only goes up to length 55 (also as expected). > My future ambition is to expand this concept to be a Rosetta Stone for the > superset of all formats supported by any known product. Small steps first. > :) Cool. With JtR's command-line dynamics, its list of supported formats is sort of "infinite", though. ;-) But I guess you'll list only those actually seen in use somewhere. BTW, I found that the command-line dynamics are much easier to use than having to remember the old numeric dynamics. Alexander
