Generate a CSR for Zimbra

New: Use our online command line generator

In order to gain some time, you can now generate your command line with our CSR creation assistant tool. Just copy/paste to finalize !

1- Create the private key and the CSR

  • The private key and the CSR are generated with the following command line:
    /opt/zimbra/bin/zmcertmgr createcsr comm -new -subject "/C=FR/ST=Calvados/L=Caen/O=TBS CERTIFICATS/CN=my.domain.com" 

  • Bu default, the key size is 2048-bit. You can choose another size by adding (after "-new"):

     -keysize 4096
    (4096 or higher).
  • Your key will be stored in:
    /opt/zimbra/ssl/zimbra/commercial/commercial.key 
    Make a backup copy of this file!
