There is no need for that -- see below. :)

Thanks for pointing me to `--hash'.
I did the same with:
$ sudo losetup -e blowfish128 -H unhashed2 /dev/loop0 /opt/POOL
and it worked. `unhashed2' is part of the `cryptoloop-support.patch' and
this is what it does:
+static void unhashed2_key_setup(unsigned char *keyStr, int ile, unsigned char
*keyBuf, int bufSize)
+{
+ memset(keyBuf, 0, bufSize);
+ strncpy((char *)keyBuf, (char *)keyStr, bufSize - 1);
+ keyBuf[bufSize - 1] = 0;
+}
Just out of curiosity: Who did this patch and what was the reason for
including it?
Thanks & regards,
Petar
