I’ve been trying to upload a ed25519-sk (security key) key to HF without luck, the non -sk variant built on the same machine worked fine. any reason why those variants are rejected ?

Hi @xaiki, sorry for the inconvenience; unfortunately we don’t support this format of security key as of now (the library we’re using to handle SSH keys hasn’t added support yet).
