Thanks for good messages! Example A: Create encryption volume and decryption by bioctl bioctl -c C -l /dev/sd0a softraid0
Example B: Create encryption volume and decryption by vnconfig vnconfig -ck vnd0 /dev/sd0a almost I use Example C: dd if=/dev/urandom of=.vnode bs=512M count=1 vnconfig -ck vnd0 .vnode newfs vnd0c mount /dev/vnd0c /mnt umount /mnt vnconfig -u vnd0 softraid encryption needs bioctl. bioctl needs device name with disklabel. Example D: dd if=/dev/urandom of=.vnode.bio bs=512M count=1 vnconfig -ck vnd0 .vnode.bio #actually no needs encrytion echo -n "a d\n0\n512M\nRAID\np\nw\nq" | disklabel -E vnd0 bioctl -c C -l vnd0d softraid0 #softraid0: CRYPTO volume attache as sd2 newfs /dev/rsd2c #it will be make other disklabel on sd2 dd if=/dev/zero of=/dev/sd2c bs=32k echo -n "a e\n0\n256M\n4.2BSD\np\nw\nq" | disklabel -E sd2 echo -n "a i\n\n\nMSDOS\np\nw\nq" | disklabel -E sd2 newfs sd2e newfs_msdos -F 32 sd2i mount /dev/sd2e /mnt mount_msdos /dev/sd2i /mnt2 umount /mnt2 umount /mnt bioctl -d sd2 vnconfig -u vnd0 The OpenBSD "Full disk encryption" is actually no need tinking as Air. And Any people (like a Rookie) didn't know how to solve the problems. Who forget or confuse it. Need good suggestion. in this case, I could get a good sugguestion.
