»Example

packer {
  required_plugins {
    sshkey = {
      version = ">= 0.1.0"
      source = "github.com/ivoronin/sshkey"
    }
  }
}

data "sshkey" "install" {
}

source "qemu" "install" {
  ssh_username              = "root"
  ssh_private_key_file      = data.sshkey.install.private_key_path
  ssh_clear_authorized_keys = true
  http_content = {
    "/preseed.cfg" = templatefile("preseed.cfg.pkrtpl", {
        "ssh_public_key" : data.sshkey.install.public_key
    })
  }
  <...>
}

build {
  sources = ["source.qemu.install"]
}

packer {  required_plugins {    sshkey = {      version = ">= 0.1.0"      source = "github.com/ivoronin/sshkey"    }  }}
data "sshkey" "install" {}
source "qemu" "install" {  ssh_username              = "root"  ssh_private_key_file      = data.sshkey.install.private_key_path  ssh_clear_authorized_keys = true  http_content = {    "/preseed.cfg" = templatefile("preseed.cfg.pkrtpl", {        "ssh_public_key" : data.sshkey.install.public_key    })  }  <...>}
build {  sources = ["source.qemu.install"]}

»Notes

Plugin generates 2048-bit RSA keys
Private key is cached in PACKER_CACHE_DIR (by default packer_cache directory is used). If you delete cached private key it will be regenerated on the next run.
Packer 1.7.3 or later is required
