SAML Encryption Error

    Applies to:
  • Legacy SecureAuth IdP
Deployment model:
  • On Premises
  • SecureAuth IdP Version Affected: All

    Description: You run into this error when trying to encrypt the SAML Assertion

    Error: at System.Convert.FromBase64_Decode(Char* startInputPtr, Int32 inputLength, Byte* startDestPtr, Int32 destLength) at System.Convert.FromBase64CharPtr(Char* inputPtr, Int32 inputLength) at System.Convert.FromBase64String(String s) at MFC.SAML20.SAMLUtil.EncryptAssertion(XmlElement xmlSAMLAssertion, String SAMLEncryptionCert, String SAMLKeyEncryptionMethod, String SAMLEncryptionMethod) at MFC.WebApp.SecureAuth.SAML20SPInit.CreateSAMLResponse(AuthnRequest authnRequest, String sUser) at MFC.WebApp.SecureAuth.SAML20SPInit.Page_Load(Object sender, EventArgs e)


    Cause: The certificate blob within the Encryption Cert is not in Base64 format.

    Resolution: If the certificate is on the IdP, export the certificate in Base-64 encoded format.  Open up the certificate on a notepad, and copy the blob minus the begin certificate and end certificate.  Copy and paste that blob in the Encryption Cert field.
