    sslspdy.com has switched from Comodo Essential SSL certificate to GGSSL Wildcard SSL certificate (generic brand for Comodo Wildcard SSL) so I can create unlimited subdomains *.sslspdy.com web sites which are all protected and covered by https and SPDY SSL. Afterall, https / SSL is part of Google's search engine ranking algorithms now :D

    With Wildcard SSL certificate, I can create many subdomain *.sslspdy.com web sites that run via https and SPDY/3.1 SSL all with the single Wildcard SSL certificate which standard SSL certificates can not do as they only cover www and non-www domain.com.

    So I can create as many https based subdomains as I want off my sslspdy.com domain

    The sslspdy.com site is my test site for deploying ECC 256 bit SSL certificates with ECDSA digital signature algorithm and to test web browser compatibility and other issues which may arise due to the newer ECC/ECDSA exchange mechanisms. You can read more about ECC SSL certificates at the links listed below:

    SSL Wildcard Nginx Configuration

    For Centmin Mod LEMP's Nginx SPDY/3.1 SSL setup for GGSSL Wildcard SSL certificate the same steps outlined at Nginx HTTPS / SSL Google SPDY configuration are needed. Just the certificate names differ.

    For GGSSL Wildcard with CSR code generated via ECC 256 bit keys & ECDSA digital signature, you will end up the following certificates provided by Comodo.
    • Root CA Certificate - AddTrustExternalCARoot.crt
    • Intermediate CA Certificate - COMODOECCAddTrustCA.crt
    • Intermediate CA Certificate - COMODOECCDomainValidationSecureServerCA.crt
    • Your GGSSL Wildcard SSL - STAR_sslspdy_com.crt
    Creating the sslspdy.com-unified.crt and sslspdy.com-trusted.crt files for Nginx vhost involve the following:

    cat STAR_sslspdy_com.crt COMODOECCDomainValidationSecureServerCA.crt COMODOECCAddTrustCA.crt > sslspdy.com-unified.crt
    cat COMODOECCAddTrustCA.crt COMODOECCDomainValidationSecureServerCA.crt AddTrustExternalCARoot.crt > sslspdy.com-trusted.crt

    Opera 25 sees sslspdy.com SSL Wildcard certificate as follows


    CSR code is generated using ECC 256 bit and sha256 signatures


    GGSSL Wildcard = Comodo Wildcard. Premium Forum users can get GGSSL Wildcard certificates quite cheaply ;)

    I couldn't find any url on the GGSSL Wildcard SSL. How much per year, etc. They have many similar SSL and I'm not sure which one you used, George.
