-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I guess I was wrong, but I thought that because of the Salt on the passwords and one-way encryption, that once they were shadowed the plaintext password could not be recovered?

First, entries in the shadowed file | which don't exist in the main file are removed. Then, shadowed | entries which don't have `x' as the password in the main file are | updated. Any missing shadowed entries are added. Finally, passwords | in the main file are replaced with `x'. These programs can be used | for initial conversion as well to update the shadowed file if the | main file is edited by hand. | | pwconv will use the values of PASS_MIN_DAYS, PASS_MAX_DAYS, and | PASS_WARN_AGE from /etc/login.defs when adding new entries to | /etc/shadow. | | Likewise, pwunconv and grpunconv are similiar. Passwords in the main | file are updated from the shadowed file. Entries which exist in the | main file but not in the shadowed file are left alone. Finally, the | shadowed file is removed. | | Some password aging information is lost by pwunconv. It will convert | what it can. | | _______________________________________________ | TriLUG mailing list | http://www.trilug.org/mailman/listinfo/trilug | TriLUG Organizational FAQ: | http://www.trilug.org/~lovelace/faq/TriLUG-faq.html - -- Jeff Bollinger University of North Carolina IT Security Analyst 105 Abernethy Hall mailto: jeff_bollinger@unc dot edu -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.0 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQE9xr1BvoVlxVBmgsURAhdRAKCQtnKd8o7vztR+NR8fQdoHYTJicwCfa4er jwB8Oou6bHtdw0KOdD6d59s= =mbaS -----END PGP SIGNATURE----- _______________________________________________ TriLUG mailing list http://www.trilug.org/mailman/listinfo/trilug TriLUG Organizational FAQ: http://www.trilug.org/~lovelace/faq/TriLUG-faq.html
