The idea is that a user may prefer a different suite of algorithms on their private email account compared to their work email account. Such identity-specific preferences can be expressed on the certifying signatures that bind User IDs to a certificate. +## A typical OpenPGP certificate, revisited + +Now that we've discussed how keys and identity components are linked together, we can have another look at the certificate from {numref}`fig-openpgp-certificate-components`.
