Error creating SP metadata when adding X509 certificate for encryption

[Lipscomb, Gary]

Hi list,

I'm trying to update a vendor supplied SP metadata file [2] with their public key certificate to encrypt assertions.

Shibboleth IdP 3.3.2 is throwing this error [1]

The vendor states
" We tested on our end signing, using this public key and was able to successfully decrypt the assertions as well. The public key is using an RSA 1_5 algo and is as specified here (https://www.w3.org/TR/2002/REC-xmlenc-core-20021210/Overview.html#rsa-1_5)."

Their metadata generation doesn't add in the certificate.
It all works if I remove the KeyDescriptor section.
Any ideas? Have I left any section out of the metadata.

Regards

Gary
