SAML AuthN Request
This tool validates an AuthN Request, its signature (if provided) and its data.
Paste the AuthN Request if you want to also validate its signature (HTTP-Redirect binding), and paste also the X.509 public certificate of the Service Provider and the RelayState parameter. If the AuthN Request contains an encrypted element, the private key of the identity provider is also required.
In the validation process the Service Provider EntityId is checked and the target URL (IdP SSO endpoint).
