Please add support for ed25519 keys. Both PuTTY and WinSCP have built-in support for ed25519 keys for quite a while now and NetBox heeds to catch up. ed25519 is replacing RSA and ECDSA in more and more places and a lack of support from NetBox becomes a real inconvenience.

I just keep the workaround info below from previous topic.
But might it is possible to add native support for ed25519 keys in default PPK version 3.

"Some hit: NetBox work with ed25519 keys, converted in Putty to v2 format "PuTTY-User-Key-File-2: ssh-ed25519"
run PUTTYGEN.EXE open exist ed25519 private key,
in menu Key > Parameters for saving key files, set PPK file version to 2
then in front window select EdDSA then save private key"
