Hi there,

As far as I remember, the NTLANMAN hash maxed at 8 and LM hashes at 13 characters... could be corrected...

I have not really heard of any 'secure' implementation with 6 character passwords - The minimum today would be:

1.) Password length: 8 characters
2.) Full complexity: Upper and lower case, numerals, alphanumerics <---- Don't forget the spacebar here!!always a good one!
3.) Max age average of around 40 - 60 days dependant
4.) History of around 10 passwords


Hope this helps,

Mike
