[erlang-questions] openssh-key-v1 pkcs #8 conversion for ed25519

[Nyirő Gergő]

Dear list,

my question is not strictly belong to erlang, but I hope my problem
is familiar to many list members.

We are planning to support ed25519 for ssh and ssl too, and
we would like to store the private keys in the same format (pkcs #8).
Unfortunately the conversion between pkcs8 and openssh-key-1
for ed25519 private key is not an easy task.

Does anyone know any library or cli tool which could be used for
this conversion?

thank for your advice in advance,
Gergo
