Bug 1272345

1. What is the nature and description of the request?
Support for The DNS-Based Authentication of Named Entities (DANE) Transport Layer Security (TLS) Protocol is missing in OpenSSL library.


2. Why do you need this? (List the business requirements here)
- To limit attack surface on TLS (by eliminating CA-trust issues imposed by current CA certificate management systems).
- To ease TLS certificate lifecycle maintenance and trust-bootstraping.
- To ease CA-rotation process.



3. How would you like to achieve this? (List the functional requirements here) 
Implement
http://tools.ietf.org/html/rfc6698
http://tools.ietf.org/html/rfc7671
into OpenSSL.


4. For each functional requirement listed, specify how Red Hat and you can test to confirm the requirement is successfully implemented.

a.
- Create own CA
- Create a certificate for TLS
- Put CA certificate into TLSA record in DNSSEC-signed zone
- Configure an application (e.g. Apache) with the cert
- Try to open a TLS connection from an application using NSS library (e.g. curl).
- The CA cert should be accepted because it will be automatically obtained from DNS.

b.
- Generate a self-signed certificate for TLS
- Put the self-signed certificate into TLSA record in DNSSEC-signed zone
- Configure an application (e.g. Apache) with the self-signed cert
- Try to open a TLS connection from an application using NSS library (e.g. curl).
- The TLS cert should be accepted because it will be automatically obtained from DNS.



5. Does you have any specific timeline dependencies and which release would they like to target (i.e. RHEL6, RHEL7)?  
RHEL 8 or if possible RHEL 7


6. List any affected packages or components.
OpenSSL library


7. Would you be able to assist in testing this functionality if implemented?"
Yes
