    Default How to generate a certificates with SHA-2?

    Hi There,

    I am looking for a way to generate a new certificate for Zimbra 7.x using SHA-2 encryption.

    Reading zmcertmgr help I did not see anything about it:

    # opt/zimbra/bin/zmcertmgr help
    /opt/zimbra/bin/zmcertmgr -help
    /opt/zimbra/bin/zmcertmgr createca [-new] [-keysize 1024] [-subject subject]
    /opt/zimbra/bin/zmcertmgr deployca
    /opt/zimbra/bin/zmcertmgr createcsr <self|comm> [-new] [-keysize 1024] [-subject subject] [-subjectAltNames "host1,host2"]
    /opt/zimbra/bin/zmcertmgr createcrt [-new] [-days validation days] [-keysize 1024] [-subject subject] [-subjectAltNames "host1,host2"]
    /opt/zimbra/bin/zmcertmgr deploycrt <self>
    /opt/zimbra/bin/zmcertmgr deploycrt <comm> [certfile] [ca_chain_file]
    /opt/zimbra/bin/zmcertmgr savecrt
    /opt/zimbra/bin/zmcertmgr viewcsr <self|comm> [csr_file]
    /opt/zimbra/bin/zmcertmgr viewdeployedcrt [all|ldap|mta|proxy|mailboxd]
    /opt/zimbra/bin/zmcertmgr viewstagedcrt <self|comm> [certfile]
    /opt/zimbra/bin/zmcertmgr verifycrt <self|comm> [priv_key] [certfile]
    /opt/zimbra/bin/zmcertmgr verifycrtchain <ca_file> <certfile>
    /opt/zimbra/bin/zmcertmgr checkcrtexpiration [-days 30] [service]
    /opt/zimbra/bin/zmcertmgr addcacert <certfile>
    /opt/zimbra/bin/zmcertmgr migrate

    By default it is generating SHA-1 encryption.

    Any suggestion about it is appreciated.
