This little tool hoped to solve the problem by formatting the JSON data so that it is easy to read and debug by human beings.
Shortly after it was created, JSON validation was added following the description set out by Douglas Crockford of in RFC 4627.
In the validation process is checked who sent the message (Id P Entity Id), who received the SAML Response (SP Entity Id) and where (SP Attribute Consume Service Endpoint) and what is the final destination (Target URL, Destination).
If the SAML Response was sent after an Authn Request, the Request ID can also be provided in order to validate it too.
The validator checks for well formedness first, meaning that your XML file must be parsable using a DOM/SAX parser, and only then does it validate your XML against the XML Schema.
The validator will report fatal errors, non-fatal errors and warnings.
Tests the supplied SPF record to see if it is valid. Except for %d, does not currently support records that include macros.To check an incoming mail request, fill out IP address from which the mail was received and the Mail From address.
