"InvalidCertificateException: Certificate chain is invalid"
Microsoft released a critical update (KB 2661254) on August 14, 2012, that ends support for certificates using the RSA algorithm that has key lengths less than 1024 bits. Shorter keys have been deemed more vulnerable to brute force attacks due to continued advances in computer processing capabilities. After applying Microsoft’s update, all certificates with key lengths less than 1024 bits will be treated as invalid. Any application that calls into the operating system to validate the digital certificates will receive an invalid certificate response whereas previously it would pass the validation.
