Subject: RE: md5_gen(0) broken for ages?
This change should fix the problem seen. NOTE the change I posted to
the rawMD5go_fnt.c should also be done.
This change is to md5_gen_fmt.c in the get_salt function:
static void *get_salt(char *ciphertext)
{
static char Salt[SALT_SIZE+1];
memset(Salt, 0, SALT_SIZE+1);
+ if (saltlen==0)
+ return Salt;
strncpy(Salt, &ciphertext[md5_gen_SALT_OFFSET], SALT_SIZE);
Salt[SALT_SIZE] = 0;
if (md5_gen_salt_as_hex)
The above should flip john into saltless mode for all saltless
Md5-gen formats.
Up to this point, I had not run any file with any data past the
hast, thus I have not seen this buggy behavior.
Jim.

Tried it. It doesn't seem to fix my problem:
$ ./john-jumbo12E1-intr-fix test.rawmd5 -fo:raw-md5 -si
Using raw-md5 mode, by linking to md5_gen(0) functions
Loaded 33837 password hashes with 489 different salts (Raw MD5 [gen])
