Bug#928668: gnome-keyring: passphrase prompt in GNOME 3 does not take correct passphrase for ed25519 key

[Yao Wei (=?UTF-8?Q?=E9=AD=8F=E9=8A=98=E5=BB=B7?=)]

Package: gnome-keyring
Version: 3.28.2-5
Severity: normal

Maintainers,

The passphrase prompt in GNOME3 cannot take correct passphrase if the
ssh key is ed25519.

Here's the procedure I tried:

1. Generate an ed25519 key with ssh-keygen
2. Copy the public key to a remote host
3. ssh to the remote and password prompt in GNOME 3 appears
4. Enter correct password but the prompt appears again, probably
   somewhere between gnome-keyring-daemon and the password prompt does
   not take the password.

Note that ssh-add, with passphrase prompt in the command line, does
work, therefore this is not the same issue as bug #738660.

Also, rsa4096 key also does work.

I haven't tried using experimental yet, but this is the same version
used in buster, hence the report.

Thank you,
Yao Wei
