Subject: Re: [ietf-provreg] EPP Server Implementer Help Needed

Hi Scott,

Although this comment might seem odd, I was wondering, why the TLS  
feature is required.

When I was in charge of .VE we decided not to include any encryption/ 
auth features besides regular user/pass simple auth.

Later on, we decided to use SSL/TLS tunneling with a sepparate  
software package, that will provide the encryption services. At first  
we used ssh, but stunnel turned out to be a better solution.
if we were to require stronger encryption, we could start by  
introducing other software packages, but taking the complications  
outside of the EPP implementation...

I donīt know if using third party software will comply with this  
requirement, because if it does, then it might be a good idea to  
switch to that instead.

Regards

Francisco
