Certify whole keyring with one private key

Is there a way to certify the whole bunch of public keys with one private key and to set the trust level to highestest. Let’s say I have 250 public keys for one organization and I have to sign one by one with one private key and I have to do this 250 times for each private key. Is there a way to automatize this proces. Please help.




There is some documentation about that for GNU/Linux:

You can do similar things I guess with powershell and batch scripts but I’m no expert on that.

I wonder though if for you would not be better of to use a curated keyring which you set e.g. to read only and use the trust model “always” (can be changed in the gpg.conf) so that all keys in the curated keyring are used as fully valid keys.
