6.1 Disabling certificate checking

In some cases clients are not really interested in host validation of the peer and whether or not the certificate can be trusted. In these cases the client can pass cert_verify_hook(cert_accept_any), calling cert_accept_any/5 which accepts any certificate. Note that this will accept literally ANY certificate presented - including ones which have expired, have been revoked, and have forged signatures. This is probably not a good idea!
