In SSO with AzureAD, when renewing a certificate to be uploaded to Box, does it matter which format [.cer] [.pem] is used? Is there a format specification?

When renewing your SSO certificate, you can use any of the following file types:

  • Accepted certificate file types are .pem, .cer, .crt, or .der.
