Decoding the key manually to not contain a passphrase allows hs-airdrop to proceed further.

I've also tested with a passphrase-protected rsa key and it worked.

I met the same issue.

I have the same issue like in the title description, but a different error message:

./bin/hs-airdrop ~/.ssh/id_ed25519 hs1.......

Passphrase:

Fixed by removing lines 1005 & 1006 which throws this error https://github.com/bcoin-org/bcrypto/blame/master/lib/ssh.js#L1005

@hexagon6 did claim work that way? i think this is where i had given up on my last attempt, but it's reassuring to find out it may still be possible with fixes to just the airdrop tool

[hexagon6]

@brandondees yes!

$ ./bin/hs-airdrop ~/.ssh/my_github_key hs1mywalletaddress

This still seems to be an issue today with ed25519 keys.

[dewey]

Yep, same issue here. I just removed the passphrase with ssh-keygen -p -f meykey_ed25519 and set it to an empty one to make it work.
