 In this Case Study , we would explore how a New Certificate request placed in a Ticketing Tool like Service Now could be managed through HWA End to End and how HWA would generate this Certificate requested while also placing a csr request ,also raising a Change on Service Now to schedule the Certificate Addition to the Keystore indicated in the original Ticket and also Creating and scheduling a Jobstream to Automate the Certificate Application Step on the given Scheduled Date and Time. An Application Team wanting to renew its Certificate on an existing keystore of their’s places a request on Service Now to generate a New Certificate while also providing other details like date and time when the Certificate is to be renewed on the Application , the exact Keystore location , Keystore Name , Certificate Name .  Fig1 Solution Realization : A Jobstream on HWA would process this request and generate a New Certificate on the fly while also Scheduling a Change Request on Service Now to manage this change , it would also gather details like the Certificate Application Date , Time , the Keystore Path , Keystore etc to be applied on the given Keystore while including these details in the Description of the Change Ticket and append a Generic Implementation Plan and Backout Plan in the Change , it would also a create a Jobstream to apply the Certificate to the Application on the Given Date and Time. SERVICENOW_GET_CERT_DESCRIPTION : This Job would be a RESTFUL GET job which would gather Description from the SNOW Ticket filtering by Assignment Group Middleware_Team to extract details from the description of the Ticket and would redirect output to an output file /tmp/cert_request_description.  Fig2 EXTRACT_CERTPATH : This Job would extract the Certificate Path from the Request Description:  Fig3 EXTRACT_CERT_APPLY_DATE : This Job would extract the Date when the Certificate is to be applied on the System from the Request Description:  Fig4 EXTRACT_CERT_APPLY_TIME : This job would extract the time when the Certificate is to be applied on the System from the Request Description:  Fig5 EXTRACT_CERT_NAME: This Job would extract the Name of the Certificate to be applied on the System from the Request Description:  Fig6 STORE_CERTPATH , STORE_CERT_APPLY_DATE , STORE_CERT_APPLY_TIME and STORE_CERT_NAME Jobs : These STORE would use jobprop utility of HWA and store all details like Certificate Path , Certificate Application Date , Certificate Application Time and Certificate Name into HWA variables and expose these Variables for the rest of the Jobstream Flow :  Fig7:  Fig8:  Fig9:  Fig10 STORE_CERT_DETAILS: This Variable Table Update Job would update a Variable Table named CERTDETAILS also associated at the Jobstream level which would update variables like CERTAPPLYDATE , CERTPATH , CERTNAME , CERTAPPLYTIME in the Variable Table from the exposed variables from the previous set of STORE Jobs:  Fig11: CERTAPPLY Job : This job would generate a Certificate based on the Certificate Path and Certificate Name passed as arguments while also generating a Certificate Signing request:  Fig12: Joblog from execution: =============================================================== = JOB : MASTER_DA#CERT_REQ_MGMT[(1157 10/22/21),(0AAAAAAAAAAABPKT)].CERTAPPLY = USER : root = JCLFILE : /home/testhwa/certcreate.sh /home/testhwa oct_2021 = TWSRCMAP : = AGENT : DAUNIX = Job Number: 789034989 = Fri 10/22/2021 11:58:26 CEST =============================================================== PATH=$1 + PATH=/home/testhwa CERTNAME=$2 + CERTNAME=oct_2021 JKSEXT=".jks" + JKSEXT=.jks JKSFILE=`echo $CERTNAME$JKSEXT` echo $CERTNAME$JKSEXT ++ echo oct_2021.jks + JKSFILE=oct_2021.jks cd ~testhwa + cd /home/testhwa /bin/keytool -genkey -alias $CERTNAME -keyalg RSA -keysize 2048 -keypass changeit -keystore $JKSFILE -validity 365 -storepass changeit -dname "CN=EU-HWS-LNX242, OU=HCLSoftware, O=HCLTechnologies, L=IN, ST=KA, C=IN" + /bin/keytool -genkey -alias oct_2021 -keyalg RSA -keysize 2048 -keypass changeit -keystore oct_2021.jks -validity 365 -storepass changeit -dname 'CN=EU-HWS-LNX242, OU=HCLSoftware, O=HCLTechnologies, L=IN, ST=KA, C=IN' keytool error: java.lang.Exception: Key pair not generated, alias <oct_2021> already exists /bin/keytool -certreq -keyalg RSA -alias $CERTNAME -file oct_2021.csr - keystore $JKSFILE -storepass changeit + /bin/keytool -certreq -keyalg RSA -alias oct_2021 -file oct_2021.csr - keystore oct_2021.jks -storepass changeit Warning: The JKS keystore uses a proprietary format.
