- START: VMSC [Options]
- LANGUAGE: Englisch
- OS: UNIX

- INSTRUCTIONS:
- (Sorry in advance if English Language is not so good in this
- README file, but I've no time and I don't feel like making a very
- good translation of Italian version of this README file ... and
- perhaps I don't know where is my good old English Dictionary ...)

- This program, in its concept, is very close to the Crack for UNIX
- by Alec Muffet, and it moves that idea into the VMS' world and so
- VMSC is an encryption/comparison program.
- Like its UNIX partner, a SYSTEM ADMINISTRATOR can, with VMSC, check
- the security level of the password that the users use in a specific
- machine running VMS operative system from version 2.0 (if it exists!)
- to version 6.0. The main difference, from a theoretic point of view,
- between a Unix' Crack and a VMS' one is that in the first one the
- PASSWD (the file that contains every encrypted passwords) can be
- read by all the users (not always, but very near to that), instead
- in the second one the SYSUAF.DAT file can be read only by the SYSTEM
- (or by users with similar privileges). In this way it's more difficult
- that our VMSC will be used by third party to find passwords over a
- VMS machine.
- This version of VMSC is just built and optimized to run over
- INTEL 386/486 machine, easy available around the world. You must
- to copy the VMS' SYSUAF.DAT file that you want to analyze over your
- DOS machine, remembering that SYSUAF is an INDEXED BINARY and so
- you must copy it with attention (on the contrary over Unix there
- is an easy moving ASCII PASSWD).
- The ZIP archive with VMSC should be compund of : all the sources,
- various makefiles for some C compilers under MSDOS, the exe's files,
- two README with some instruction and some ascii dictionary.
- The list of options that you can use into the line command with VMSC
- is callable running VMSC with '-h' or '-?' option (ex: VMSC -h) and
- you will see this output :

-
- VMSC [Options]
- Options :
-
- -?,-h,-H : Show this help page.
- -s : Single word mode.
- -u : Single user mode.
- -l : Look all users' record.
- -c : Create a namelist from a SYSUAF to use as words.
- -k : Don't skip user account disabled.
- -t : Test crypt result for proper encryption.
- -d : Debug mode.
- -q : Quiet mode.
- -S file : Specific SYSUAF file.
- -V file : Specific vocabulary file.
- -O file : Specific output file.
- -P pass : Specific password for single word mode.
- -L user : Look a specific user's record.
- -U name : Specific name for single user mode.
-
-
- Usually you must give to the program the name of your SYSUAF, the
- name of a dictionary file (a word under the previous one, look the
- dictionary enclosed for example) and the name of the OUTPUT file.
- The specific options are:
-
- '-s' : with that you can give to the program only a word as password,
- instead using a dictionary file;
-
- '-u' : with that you can check all a dictionary over a single user;
-
- '-l' : show all users' record;
-
- '-c' : make a text file, that you can use as dictionary, with all
- the usernames into the analysed SYSUAF;
-
- '-k' : usually the program don't analyse user with DISUSER flag setted
- on, with this option VMSC does it;
-
- '-t' : check that all encryptions are good;
-
- '-d' : debug mode, every single step of encryption/comparison of
- every user with all the words is showed over your screen;
-
- '-q' : no output over your screen;
-
- '-S file' : name of the SYSUAF.DAT file (if not selected, the program
- will ask for that without problem);
-
- '-V file' : name of the dictionary file (if not selected, the program
- will ask fot that);
-
- '-O file' : name of the output file (if not selected, the program will
- ask for that);
-
- '-L user' : show datas of an user into the SYSUAF.DAT;
-
- '-U name' : name of the user for single user mode.
-
- You can stop VMSC with CTRL+C, or it stops itself when all words are
- checked with all users.
-
- Into the output file there will be every users with hit password, in this
- form :
-
- User : [USER], Password : [PASS]
-
- and at the end of the file there will be some statistic about the analyse :
-
- *=============================================================================*
-
- Users : 546
- Password found : 72
- Comparisons : 546
- Time elapsed in seconds: 14
- Comparisons/seconds : 39.00
- Encryption performance : 13.19%
-
- *=============================================================================*
-
- VMSC is a FREEWARE program and it goes out with all its sources, if
- anybody finds a way to optimize all that or if anybody writes down
- a good version of VMSC for VMS or UNIX with a speed at least faster
- than a 486DX2 at 66Mhz under DOS, we will very happy to receive that.
- If any commercial 'entity' (or institution) finds a way to make money
- with our program will be nice that it contacts us.
- That's all, good work with VMSC V1.0.
