Version 1.1.2 is considered to be deprecated. If you have used it, we strongly recommend that you migrate to the new version.

We rebuilt the toolkit on 2.0.0, so code/settings that you had been using in the previous version will no longer be compatible.

In production also we highly recommend to register on the settings the IdP certificate instead of using the fingerprint method. The fingerprint, is a hash, so at the end is open to a collision attack that can end on a signature validation bypass. Other SAML toolkits deprecated that mechanism, we maintain it for compatibility and also to be used on test environment.

The IdPMetadataParser class does not validate in any way the URL that is introduced in order to be parsed.

Usually the same administrator that handles the Service Provider also sets the URL to the IdP, which should be a trusted resource.

### IdP with multiple certificates

In some scenarios the IdP uses different certificates for
signing/encryption, or is under key rollover phase and more than one certificate is published on IdP metadata.

In order to handle that the toolkit offers the `onelogin.saml2.idp.x509certMulti` parameters where you can set additional certificates that will be used to validate IdP signature. However just the certificate set in `onelogin.saml2.idp.x509cert` parameter will be used for encrypting.
