DES 7bit characters - PHloGiSTo - 11-30-2011
How do the characters of a password get clipped or altered to conform to the 7bit input for DES characters? When i use maskprocessor with -1=?l?u?d?s?D?F?R ?1 i get 143 different characters, yet if DES is only using 7bits then there is a maximum 128 possible options.
I would like to create a rule to append every possible character to the end of a wordlist, without duplicates.

DES algorithm shifts each char 1 bit to the left (8 - 1 = 7). For example, german ö (oe) encoded as 8 bit iso-8859-1 is 0xf6 (11110110), shifting it one to the left results in (11101100), which is the same result as the input 0x76 would result. in other words its converted to "v".

how is this related to 7bit keys?
