Hello, my implemented SAML flow suddenly stopped working with the following Error message:
Uncaught PHP Exception LightSaml\Error\LightSamlSecurityException: "Algorithm mismatch between input key and key used to encrypt the symmetric key for the message. Input key algo is: 'http://www.w3.org/2001/04/xmldsig-more#rsa-sha256'. Message key algo is 'http://www.w3.org/2001/04/xmlenc#rsa-oaep-mgf1p'"
What is in this context the "input key" and what is the "message key"?
- Does it mean that the ADFS Server returns a message that is encrypted with rsa-oaep-mgf1p,
but the key I created is encrypted with rsa-sha256?
Because I did not change anything on my side, I assume that the ADFS settings were changed by someone. Is this the right conclusion for this case?
Any help would be appreciated, Thx. :-)
