We cannot then change key structure later easily. Yes, I agree. but the key selection based on sector number restricts the option of having a larger block size used for encryption. >> + unsigned int key_size; >> + unsigned int key_extra_size; >> + unsigned int key_parts; /* independent parts in key buffer */ > > ^^^ these key sizes you probably mean by key management. Yes, I mean splitting the keys into subkeys based on the keycount parameter (as mentioned below) to the dm-crypt. cipher[:keycount]-mode-iv:ivopts aes:2-cbc-essiv:sha256 > It is based on way how the key is currently sent into kernel > (one hexa string in ioctl that needs to be split) and have to be changed in future. -Binoy -- 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
