can't import JuiceSSH ED25519 private keys

[tf2k]

I've been asked to troubleshoot an issue where an SSH key generated on an Android Smartphone with JuiceSSH fails to import / fails to get decoded and the widget returns: "wrong passphrase", after entering the correct passphrase.

The key can be used on a Linux Client without any isues, and it works if the passphrase on the key gets changed on Linux.

Steps to reproduce:
Install Juice SSH 3.2.2 on the Smartphone
create new identity, ED25519 Key type, set a passphrase and export the key to the clipboard

open the Stratum0 Widget (version 8.0.0-play)

• go to Settings
• enter the nickname
• press the "refresh" symbol
• the SSH key gets imported from the clipboard automatically
• the Widget asks for the SSH passphrase, enter it
• app states "wrong password"

are we hitting a bug in the sshj Library?:
hierynomus/sshj#770

Thanks for your report. I'd rather not install an app to reproduce, can you please attach a key that exhibits this behavior?

sure!

passphrase: mypassphrase
juice_ssh_private_key.txt
juice_ssh_public_key.txt

ssh-keygen -l -f juice_ssh_private_key.txt

I am just the messenger, i've heard that the person with the originating issue has already got in touch with you.
(oh dear, and i see that JuiceSSH is killing the nice formatting of the key with respect to the line lenghts ...) nothing compares against a ssh-keygen on a pc.
