Subject: Re: Custom Windows build 1.8.0.9 - What happened to
zip2john?
Pretty much confirming what you said, I've found some documentation on
Cygwin <https://cygwin.com/cygwin-ug-net/using-specialnames.html> in the
POSIX devices section saying that the /dev/shm directory is very
important for some programs. Additionally, there appears to be an
unanswered thread here on john-dev
<http://www.openwall.com/lists/john-dev/2014/06/06/3> talking about this
message in particular. Sounds like there may be a bug here?
About the non-UTF8, I just opened the output file in Notepad++, which
says it's encoded in UCS-2 LE. (I don't think I've heard of that one
before!) I'm running these commands from Windows PowerShell, perhaps
that's screwing with things?
I wouldn't mind sharing the hash with a developer although I would like
it to remain private, if there is a developer available to accept this file?
Running the command without show:
.\run\john.exe .\zip.hash
Warning: '/dev/shm' does not exists or is not a directory.
POSIX shared memory objects require the existance of this directory.
Create the directory '/dev/shm' and set the permissions to 01777.
For instance on the command line: mkdir -m 01777 /dev/shm
Warning: invalid UTF-8 seen reading .\zip.hash
Using default input encoding: UTF-8
No password hashes loaded (see FAQ)
