Date: Fri, 5 Aug 2011 02:36:44 +0200 From: Lukas Odzioba <lukas.odzioba@...il.com> To: john-dev@...ts.openwall.com Subject: SALT_SIZE I've got a question what john does with SALT_SIZE constant in fmt_main, and how it should looks. In sha256/512 crypt salt looks like: $5$salt(up to 16chars)$ciphertext or $5$rounds=(1000-999999999)$salt(up to 16chars)$ciphertext It will be ok if my salt(char *ciphertext) return (salt(upto16chars)+4Bytes int decoded rounds),and SALT_SIZE then would be (16+4)? Because john is comparing salts maybe just return everyting between $5$ and $ciphertext adding rounds=DEFAULT if it is not present then: $5$saltstring$ciphertext $5$rounds=DEFAULT$saltstring$ciphertext will be reckognized as the same salt, and SALT_SIZE should be strlen("rounds=999999999")+16; Lukas
