If the last certificate in the chain was self-signed (as it usually should be, because the chain is built up to the self-signed root certificate), Validity can be cv Self Signed, if the topmost certificate was not found in the list of trusted certificates, or cv Ok if the topmost certificate is trusted.When Complete Chain Validation = true and the certificate is found to be not valid, certificate validation continues, i.e. This lets you create validation report which should include all certificates in the chain.When Complete Chain Validation = false and the certificate is not valid, further validation is not performed and Validate() method returns immediately.TLS 1.0 is a name for what was supposed to be SSL 3.1.
