First return on google search of "pwdump file format" returns this structure:

Each string of a PwDump file is compiled in the following format: "UserName:RID:LMhash:NThash:FullName,Description:HomeDirectory:" .

Hi Miguel,

There's no "standard" format, but the format that's most often used (by
pwdump and fgdump, for example) is:

username:rid:lanman:ntlm:::

rid is basically the user id on the system -- 500 = admin, 501 = guest,
1000+ = standard users.

lanman and ntlm are two different types of hashes -- lanman is weak,
ntlm is reasonable.

I'm not sure what, if anything the last three spots are.

Hope that helps!

Ron
