For versions up to 1.7.8-jumbo-8 inclusive, the maximum is:
#define CHARSET_MIN '0'
#define CHARSET_MAX 'z'
#define CHARSET_SIZE (CHARSET_MAX - CHARSET_MIN + 1)
#define CHARSET_LENGTH 10
#define CHARSET_SCALE 26
That is, you can only go up to length 10 with this charset. For version
1.7.9 (and for 1.7.9-jumbo when we release it), there's practically no
maximum for CHARSET_LENGTH (any sane value will do - e.g., 16), and
there's no CHARSET_SCALE. I understand that for hash types you're
typically cracking you need -jumbo, so either use the settings above
(lengths up to 10) or wait for 1.7.9-jumbo. Well, or use these settings
for now and use a larger CHARSET_LENGTH once you upgrade to 1.7.9-jumbo.
