Adding subkeys

How to generate an additional subkey

To generate and add a subkey to an existing certificate use sq subkey add:

$ sq key subkey add --cert $FINGERPRINT --can-sign  --without-password  

This example limits the abilities of the subkey to signing, and opts out of password protection.

How to bind an existing subkey to another certificate

$ sq key subkey bind --key $KEY_TO_BE_BOUND_FINGERPRINT --cert $FINGERPRINT
