Hi all,
I was wondering if is at all possible to discover a password one
char at a time.
Normally, you either get the password right or wrong (all or nothing).
Does anyone know if this can be done? Does it depend on the encryption
algorithm
used to encrypt the password? Is that a difference for 1 and/or 2 way
passwords?
Not generally. Perhaps with weak encryption techniques such as adding the values of two ascii characters together. example: This is the text to be encrypted. passwordpasswordpasswordpasswordp In such a case, it could be possible to learn the password one character at a time. In most cases, though, a stronger encryption is used and this isn't possible. -- Chris Largret <http://daga.dyndns.org>
