Hi |

I read the following artivle |
| 4 |
http://www.securityfocus.com/news/11355/2 |
| 5 |
which has prompted me to reconsider my security setup, it is a home |
| 6 |
system but with open ssh ports and similar. |
| 7 |
My specific question is this - What method/cryptography is used to |
| 8 |
create the passwd hash under PAM ie. is it vunerable to rainbow type |
| 9 |
hash tables. |
| 10 |
-----snip---- ^^ article |
| 11 |
RainbowCrack Online will offer 11 tables covering six different hash |
| 12 |
algorithms, including LanMan, MD5, MySQL 323, and SHA-1 |
| 13 |
-----snip----- |
| 14 |
|
| 15 |
now that said it is quite possible that I have got the wrong end of |
| 16 |
the stick so to speak, ie. I know that PAM handles login etc but is it |
| 17 |
PAM that generates the hash of my chosen password? |
| 18 |
If so can I expand my question to ask what program and further what |
| 19 |
algorithm is used to do this task. |
| 20 |
This is for my system of course but I guess the principle can be |
| 21 |
applied to many systems. |
| 22 |

EDIT |
| 24 |
As I was writing this I checked man passwd which seems to have |
| 25 |
answered my question on the whole |
| 26 |

| 27 |
The UNIX System encryption |
| 28 |
method is based on the NBS DES algorithm and is very secure. |

|
| 31 |
I have left my earlier question [more or less answered] just for some |
| 32 |
confirmation, but the new point is - |
| 33 |
Does the "NBS DES algorithm" come under the "salt" method? and is it |
| 34 |
therefore immune to attacks of the hash table variety? |
| 35 |

ps. I know the above is a little disjointed but I am stumbling in the |
| 41 |
dark a little here. |
