This should not be allocated on the stack. But anyway, I see that the reason for this is to introduce multikey feature (compatible with loop-AES mode). That's interesting idea. But please can you add more explanation into documentation about this mode? Is there any paper which analyses that mode - if so can you add link to description? (and yes, I know loop-AES documentation:-) Milan -- mbroz@xxxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-crypto" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
