Alkaline attempts to write a file called ./certificate.alk containing the unlock key. It is possible that this
file could not be written or cannot be read due to permissions or other related problems.
Check that the file is being written in the same directory as the one you run Alkaline from.
If it exists, delete this file and resubmit a certificate. Check for the file again.
Try creating this file manually and copy-paste the certificate into it.
Make sure that you are running Alkaline as the same user all the time and from the same directory.
If you need to start Alkaline automatically on a unix server, make sure that you are running the daemon
with the same permissions. You might need to suid the binary. For more information about suid, please
