Tested using a parameter file

    Key-Type: EdDSA
    Key-Length: 1024
    Key-Grip: 09D9AE3D494F7888C93BE5106AD8A734A87617F0
    Key-Usage: sign
    Serial: random
    Name-DN: CN=dummy test ed25519

where the keygrip is from a gpg generated Ed25519 key.  ECDSA was
tested using

    Key-Type: ECDSA
    Key-Length: 1024
    Key-Grip: 8E06A180EFFE4C65B812150CAF19BF30C0689A4C
    Key-Usage: sign
    Serial: random
    Name-DN: CN=dummy test nistp256

and RSA using

    Key-Type: RSA
    Key-Length: 2048
    Key-Grip: C6A6390E9388CDBAD71EAEA698233FE5E04F001E
    Key-Usage: sign
    Serial: random
    Name-DN: CN=dummy test rsa

The command used in all cases is

  gpgsm -v --gen-key --batch  a.parm >a.crt
  gpgsm -v --import <a.crt

More support, in particular in the user interface, is required and
will follow soon.
