I'm trying to do this in a script, but it doesn't work on the command line, either: > > $ echo "lukssecpwd" | sudo cryptsetup -c twofish-xts-plain64 -s 512 luksFormat /dev/loop5 - > $ echo "lukssecpwd" | sudo cryptsetup open /dev/loop5 crypt.secret > No key available with this passphrase. Norepro on up-to-date Debian Buster with cryptsetup 2.1.0 (package version 2:2.1.0-5+deb10u2) with kernel 4.19.0-10-amd64 (package version 4.19.132-1) reporting build date 2020-07-24. # truncate -s 100M /root/lukstest # losetup -f /root/lukstest # losetup -l NAME SIZELIMIT OFFSET AUTOCLEAR RO BACK-FILE DIO LOG-SEC /dev/loop0 0 0 0 0 /root/lukstest 0 512 # echo "lukssecpwd" | cryptsetup luksFormat /dev/loop0 # echo "lukssecpwd" | cryptsetup open /dev/loop0 lukstest.loop0 # ls -l /dev/mapper/lukstest.loop0 lrwxrwxrwx 1 root root 7 Aug 9 09:37 /dev/mapper/lukstest.loop0 -> ../dm-9 # cryptsetup close lukstest.loop0 # ls -l /dev/mapper/lukstest.loop0 ls: cannot access '/dev/mapper/lukstest.loop0': No such file or directory # Seems to work just fine all the way through. Using echo to pipe the passphrase into luksFormat and then entering it manually into the later cryptsetup open invocation also works fine for me. That said, maybe adding "--key-file -" and dropping the "-" from the luksFormat command might help? If not, please try it again with --debug and show us the output of that. -- Michael Kjörling • https://michael.kjorling.se • michael@xxxxxxxxxxx “Remember when, on the Internet, nobody cared that you were a dog?” _______________________________________________ dm-crypt mailing list dm-crypt@xxxxxxxx https://www.saout.de/mailman/listinfo/dm-crypt
