From the documentation
MaxLen = LENGTH
Maximum password length to try. The default is 8 (or CHARSET_LENGTH as defined in src/params.h at compile time).
I've compiled it to support up to 62 characters, modified john.conf, but when running
john it returns:
Incompatible charset file: $JOHN/alnum.chr
That's when using
--incremental=alnum, but happens with any method. Why does this happens? Which are the exact modifications or parameters to support 62 characters?
Thanks in advance.
