Decoding encrypted attributes from an IDP

At Scott Cantor's suggestion, I asked our partner to encrypt the whole
assertion, rather than just the attributes (they took it upon themselves to
have the attributes remain encrypted as well, inside the already encrypted
assertion? Seems like too much encryption to me).
Now, we are seeing errors like this in Syslog:
Jul 23 19:18:21 ip-10-90-230-192 shibboleth-sp: 1343071101 ERROR
Shibboleth.Listener [24585] shib_check_user: remoted message returned an
error: A valid authentication statement was not found in the incoming
message.
And this in shibd.log:
2012-07-23 19:19:33 DEBUG XMLTooling.CredentialCriteria [16]: key algorithm
didn't match ('AES' != 'RSA')
Is this something I can modify in our config? I am certain that their
metadata told us they would be using RSA, and since those are two
completely different encryption modes, it seems like this might be more
them than us?
Thanks,
Rob
