Description Luiz Eduardo Cordeiro 2015-11-04 19:34:30 UTC 
Hello,

I've added an ED25519 ssh key to gpg-agent (gnupg-2.1.8) and,
when I use it, it gives this error:

key_from_blob: ed25519 len 31 != 32
key_free: key is NULL

No way to login on the remote machine via ssh...

> ssh-add ~/.ssh/id_ed25519
Enter passphrase for /home/XXX/.ssh/id_ed25519:
Identity added: /home/XXX/.ssh/id_ed25519 (/home/XXX/.ssh/id_ed25519)

> ssh user@example.com
key_from_blob: ed25519 len 31 != 32
key_free: key is NULL

It works if the key isn't added to gpg-agent.

Regards,
Luiz Eduardo

Just saw exactly this problem with gnupg-2.1.11_1

I'm trying to get a handle on the gnupg PRs. Is this still an issue?

I haven't had a response on this PR in over 3 months, so I'm closing it out. If this is still a problem, let me know and I can re-open it.
