The issue was fixed in version 1.0.5 (see Version History).
Thank you for pointing to this issue.
This is change in version 1.0.4, which now requires
~/.ssh/authorized_keys file format. However, we considered this as unwanted change and we will add automatic detection of the format.
If you want to use version 1.0.4 please, convert your public key to:
ssh-rsa AAAAB3NzaC1yc2EAAAABJQAAAQEAmNbXgp0nffCa4pPEbV8+lI6/5kQFflfzfnc8I5lc5BGxoKBiueyb8jnG29NtzZyNsh7ImR6Eaq6xyCoW0KY42EJPmZbJySBFcqJr3Mv55B3ltHsRjWqM5c2gsIbTCkhW5gblY+PSgpKX/ohfpSB2MA3BH1rlwdxNMguYG/wyqloflqEhLBfj/h1CQUeU8Fr4w2IfLEe7WziFEsdxaOusvJ1yZ/AQJhUT1Eb8AnMeOX/EJmepR/s6aJzYWkJbKd3/YL8SCL9NY0X++3g1zIm7eiNq2QtmG+OxDELp4EqYBhm5qxQYzQ3peH3ByitmvKMG4M0GnZgkrrI4H1wTuuIoAQ== rsa-key-20180522
