Thanks for the script, but I tried it and doesn't work for me. The main problem if found is in generating RSA keys
with the "export-reset-subkey-passwd" option. Seems that it's not working anymore (https://dev.gnupg.org/T1753).
And also, generation of the "hash.key" file doesn't work. The "gpg --list-keys" output is a bit different now.

Fixing all this things, at the end, It cannot generate the public key file (id_rsa.pub) because the command "ssh-keygen -y -f id_rsa" is asking for a passphrase and don't like the one I provide.

Anyway, Thanks for your effort! :-)

I also found that this no longer works due to the changes to GPG, however I found the following tutorial helpful:

I'll be updating the script soon. I'm setting up a new computer and I'll be taking notes of my progress. Thanks for your comments
