Re: [openssl-users] Subject CN and SANs

A bit off-topic but is it also a good idea to follow these guidelines in non-browser use cases, for example for a client certificate which is used to autenticate on a TLS connection which will be used for another protocol such as MQTT? In this case the SubjectCN looks like a "natural" place to put

As it happens I am the proud owner of a made-in-UK Mathmos Lava Lamp and a couple of their Space Projectors : however I don't use them as a RNG. I am thinking more about the fact that there are a lot of devices which * have no hardware TRNG on board * do have one or more connections to wired or

I've also encountered this quite often, and I have a feeling that on today's connected devices there may be a lot of entropy "in the air" (quite literally) which is not being captured. Does any one know of research in this area? > Hi Scott > > I don’t know your OS or environment, have you tried

You should be able to do this using stunnel: see for example https://www.elastic.co/guide/en/cloud/current/tunneling-ssl.html where your telnet commands would be the "client which supports only http". But you can also learn a lot by playing with curl ... > I know that this is a TLS related quest

As the maintainer of an "alternative" JavaVM I can confirm that we absolutely had to support library unloading because one customer was using it heavily - and that was quite a few years ago. Early Sun VMs didn't support library unloading, but then those VMs also did not garbage-collect obsolete cla

ck. In your case you're using POST, so no conversion is done by the sender but for some reason the server is still unconverting. So you need to either do URL-encoding on the client or by-pass the decoding on the server, whichever is easier. Good luck, Chris Chris Gray /k/ Embedded
