    Angry SSL Certificates Problem

    Hello there,
    I make 2 different ssl certificates with openssl for apache web server using these commands:
    openssl genrsa -des3 -out ca.key 1024
    openssl req -new -x509 -days 10000 -key ca.key -out ca.crt
    and removing passphrase with openssl -rsa -in ca.key -out ca.key

    With this, I made 2 certificates one for www.domain.com and another for mail.domain.com

    I putted in httpd.conf with a syntax like that:

    <VirtualHost ip:443>
    DocumentRoot "/path/"
    ServerName mail.domain.com
    ServerAdmin chris@domain.com
    SSLEngine on
    SSLCipherSuite ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP:+eNULL
    SSLCertificateFile /etc/httpd/newssl/ca.crt *
    SSLCertificateKeyFile /etc/httpd/newssl/ca.key *
    <Files ~ "\.(cgi|shtml|phtml|php3?)$">
    SSLOptions +StdEnvVars
    </Files>
    SetEnvIf User-Agent ".*MSIE.*" \
    nokeepalive ssl-unclean-shutdown \
    downgrade-1.0 force-response-1.0
    </VirtualHost>
    * = the host www.domain.com is another files named wwwca.key/crt not the sames ofcourse

    And I have this problem
    It workss just fine but either www.domain.com and mail.domain.com uses the mail.domain.com SSL Certificate. The problem: It cause warning messages when trying to reach https://www.domain.com saying that the crt is for mail.domain.com

    Any solutions ?

    Hi

    As far as I know, the SSL handshake occurs before the HTTP1.1
    request resolves for the name-based virtual host directory.

    Hence, Name-based virtual hosting cannot be used with SSL secure servers
    because of that very nature of the SSL protocol[1].
    I assume that the warning is for www.domain.com because (I guess)
    a nslookup for your IP will return mail.domain.com.


    The only way out I see is to switch to IP-based virtual hosts, which
    might not be easily available.

    /edit: quite a good read has been done by Robert Colbey[2].
    /edit2:

    excellent - I've stumpled across an answer[3], which is almost identical
    to mine. However, two more suggestions are given:
    2. Obtained a wildcard certificate in the form of "*.domain.com"
    3. Use a different Port for each Name-Based Virtual Host
    2. could work for you,
    3. I guess not (if both are assumed to use port 80)

    Cheers

    Absolutely right you must use IP based vrtual hosts. It's the only way I ever got it to work. That was such a pain in the ass. SSL can kiss my ass. I hate that 2 weeks, wasted learning that.
