Can x/crypto/ssh parse OpenSSH's ed25519 private key files?

ParseRawPrivateKeyWithPassphrase returns "ssh: cannot decode encrypted private keys" as error.

x/crypto/ssh does support OpenSSH's ed25519 private key files.

However, it looks like it does not support encrypted private keys in the OpenSSH format.

See https://github.com/golang/crypto/blob/9f005a07e0d31d45e6656d241bb5c0f2efd4bc94/ssh/keys.go#L922 and https://github.com/openssh/openssh-portable/blob/master/PROTOCOL.key

Hi Chandru,

I made a library to support openssh ed25519 key format.

It can be used as a drop-in replacement of `ssh.ParsePrivateKey` as shown here: https://github.com/fudanchii/edssh

That library will not work either.

See https://github.com/fudanchii/edssh/blob/bd7d88fd1d85351bf598cdcd1fb7b04528cf42e2/keys.go#L44

Correct, apologies I think I'm half asleep when I replied before. Please ignore my reply before.
