blkid and aes-cbc-plain/aes-cbc-essiv:sha256
when a plain volume is created with "aes-cbc-plain" and opened with "aes-cbc-essiv:sha256", the blkid program correctly reads the file system of the volume but mount command fails to mount it. Is this behavior expected behavior?
I am the developer of zulucrypt, the frontend to cryptsetup and i support both by first trying to open the volume with "aes-cbc-essiv:sha256" and then with "aes-cbc-plain" if the former fail.This allows the tool to seamlessly open "old" plain volumes in legacy mode
The above works but the mount system call adds ugly looking logs to /var/syslog when it fails to mount the volume the first time around i am trying to see if i can get around this.
It would have been great if blkid would fail to read the file system to tell me the plain volume is opened in wrong mode but it reads it correctly leaving it up to mount command to notice the wrong mode and then fail to mount and add the ugly looking log entry.
can i use any cryptsetup API to distinguish volumes created with those two cyphers?
