All,


This email commences a six-week public discussion of TWCA’s request to include the following two (2) certificates as publicly trusted root certificates in one or more CCADB Root Store Member’s program. This discussion period is scheduled to close on June 3, 2024.


The purpose of this public discussion process is to promote openness and transparency. However, each Root Store makes its inclusion decisions independently, on its own timelines, and based on its own inclusion criteria. Successful completion of this public discussion process does not guarantee any favorable action by any Root Store.  


Anyone with concerns or questions is urged to raise them on this CCADB Public list by replying directly in this discussion thread. Likewise, a representative of the applicant must promptly respond directly in the discussion thread to all questions that are posted.

On April 22, 2024, we began a six-week, public discussion on the request from TWCA for inclusion of its root CA certificate(s):
    The public discussion period has now ended.

    We did not receive any objections or other questions or comments in opposition to TWCA’s request. We thank the community for its review and consideration during this period. Root Store Programs will make final inclusion decisions independently, on their own timelines, and based on each Root Store Member’s inclusion criteria. Further discussion may take place in the independently managed Root Store community forums (i.e., MDSP).


    Thank you
    -Chris, on behalf of the CCADB Steering Committee
