It allowed unlimited issuance of certificates such as HTTPS, mail-signing, document-signing, and some other types that could be locked to a DNS domain. However, there was still a cost per certificate and the up-front cost was huge, something like $100K. reply.TrustAnchor (X509Certificate trustedCert, byte[] nameConstraints) Creates an instance of TrustAnchor with the specified X509Certificate and optional name constraints, which are intended to be used as additional constraints when validating an X.509 certification path.Inits this NameConstraints implementation with an ASN1object representing the value of this extension..

To reduce the risk posed by unconstrained CAs, Mozilla proposes to develop a list of name constraints to be applied to each root CAs in its program. These constraints would be published alongside the CA definitions in the root CA list.One of the problems with name constraints today is that they're not supported across all platforms, for example on Apple devices. This leads to the following problem: In order to protect all platforms against misissued certificates from name constrained intermediates, the name constraint extension would have to be marked critical.TrustAnchor public TrustAnchor(X509Certificate trustedCert, byte[] nameConstraints) Creates an instance of TrustAnchor with the specified X509Certificate and optional name constraints, which are intended to be used as additional constraints when validating an X.509 certification path..

10. There are significant benefits of giving explicit names to your constraints. Just a few examples: You can drop them by name. If you use conventions when choosing the name, then you can collect them from meta tables and process them programmatically. answered May 5, 2011 at 12:53. bpgergo.

You need to configure the correct OpenSSL extensions for the CA and the certificates, and the easiest way is to pass them in in an ini file. First, generate your private key and certificate signing request for the CA. I did mine with a 4096-bit RSA key: 1. 2. openssl genrsa -aes256 -out ca.key.pem 4096.

Typically the application will contain an option to point to an extension section. Each line of the extension section takes the form: extension_name= [critical,] extension_options. If critical is present then the extension will be critical. The format of extension_options depends on the value of extension_name .
