I have been using keepassxc (https://keepassxc.org) on debian. I just
tried to install it on devuan testing, but there was no such package.
I assume that it runs systemd rather than linux?

Can anyone suggest a secure reliable compatible ( KeePass 2.x (.kdbx)
database formats KDBX 3.1 and KDBX 4 ) program that I can use on devuan
so that I can share the same database file between machines. In my case,
said file resides on a USB thumb encrytped drive, so there are two
levels of encryption, and the database is on temporarily on any one
machine: this for explanation.

Thanks,
