key algorithm didn't match ('AES' != 'RSA') failed to decrypt assertion: Unable to locate an encrypted key.

[Lipscomb, Gary]

Hi list,

Shibboleth SP v3.0.2
Shibboleth IDP v3.3.3
RHEL 7

This is our first clean install of a new  SP v3.0.2 and trying to resolve the above issue.  All the rest have been upgrades and still use the v2 configuration.

Metadata sent to IdP generated from /Shibboleth.sso/Metadata. The public keys in the metadata for signing and encryption match the appropriate certs on the SP.
Where do I look next ?

Regards

Gary
