securing: request certificate and creation of keystore

 

remove existing keystore:

#rm -f /data/openmeetings/conf/keystore

 

 

create new keystore:

#/opt/jdk1.7.0_51/jre/bin/keytool -keysize 2048 -genkey -alias red5 -keyalg RSA -keystore /data/openmeetings/conf/keystore

 

Screenshot-16

 

 

create CSR:

#/opt/jdk1.7.0_51/jre/bin/keytool -certreq -keyalg RSA -alias red5 -file /data/openmeetings/conf/red5.csr -keystore /data/openmeetings/conf/keystore

 

Screenshot-17

 

 

submit CSR with Digicert (this is the CA where I purchased a wildcard certificate – see http://www.digicert.com/ssl-support/duplicate-ssl-certificates.htm)

 

log in to https://www.digicert.com/custsupport/
click on your order
click on “get a duplicate”
upload created CSR, select Tomcat
wait for a fiew minutes, download certificaat from the same page to /install/openmeeting/certs, format: individual certs (zipped)

 
#cd /install/openmeetings/certs && unzip AllCerts.zip && cd certs

 

 

install root certificate:

#/opt/jdk1.7.0_51/jre/bin/keytool -import -alias root -keystore /data/openmeetings/conf/keystore -trustcacerts -file TrustedRoot.crt

 

 

install intermediate certificate:
#/opt/jdk1.7.0_51/jre/bin/keytool -import -alias intermed -keystore /data/openmeetings/conf/keystore -trustcacerts -file DigiCertCA.crt

 

install server certificate – alias moet hetzelfde zijn als van de CSR:

#/opt/jdk1.7.0_51/jre/bin/keytool -import -alias red5 -keystore /data/openmeetings/conf/keystore -trustcacerts -file crt_file.crt

 
check contents keystore:
#/opt/jdk1.7.0_51/jre/bin/keytool -v -list -keystore /data/openmeetings/conf/keystore

 

Screenshot-18

 

 

copy keystore to keystore.screen to secure the screen sharing functionality

#cp /data/openmeetings/conf/keystore /data/openmeetings/conf/keystore.screen

 

 
Secure RMTP:

change config files:

 

# vi /data/openmeetings/conf/red5-core.xml

below <!– RTMPS –> remove the comment characters in order to make the section active

also replace:

<property name=”keystoreFile” value=”conf/keystore” />
with:
<property name=”keystoreFile” value=”/data/openmeetings/conf/keystore” />
