May 25, 2018 in WebServer

Installing your Certificate on Java Based Web Servers

  • You will receive 4 files in a zip file from Sectigo.
  • These must be imported in the correct order:
Root AddTrustExternalCARoot.crt
Intermediate CA UTNAddTrustServerCA.crt
Intermediate CA PositiveSSLCA.crt
domain/site certificate yourdomainname.crt

Or You can download the Positive ssl Root and Intermediate files from here.

  • Please replace the example keystore name 'domain.key' with your keystore name
  • Use the keytool command to import the certificates as follows:

keytool -import -trustcacerts -alias root -file (AddTrustExternalCARoot.crt) -keystore domain.key
keytool -import -trustcacerts -alias UTNADD -file (UTNAddTrustServerCA.crt) -keystore domain.key

keytool -import -trustcacerts -alias POSITIVESSL -file (PositiveSSLCA.crt) -keystore domain.key

  • Use the same process for the site certificate using the keytool command
  • If you are using an alias then please include the alias command in the string. Example:
keytool -import -trustcacerts -alias yyy (where yyy is the alias specified during CSR creation) -file domain.crt -keystore domain.key


  • The password is then requested.
  • Enter keystore password: (This is the one used during CSR creation)
