Publickey Algorithm IDs for --command-fd

[David Url]

Hello,

I was trying to automate the generation of subkeys, using the --command-fd option like this:
gpg --homedir /tmp/gnupgtest --status-fd 2 --no-tty --command-fd 0 --with-colons --edit-key E458A481 addkey

But i could not find the public key algorithm ids for ‘GET_LINE keygen.algo’ anywhere in the documentation.
It looks like the integers from the commandline interface without --command-fd, but is there any documentation on that?

Regards,
David
