Shell Script to find the Expiry Date of a Certificate using orapki

Shell Script to find the Expiry Date of a Certificate using orapki

I am sharing the script to find the expiry date of the certificate and send mail 30 days before expiration.

My Certificate: Server_certificate.cer

Script:

. ~/.bash_profile

cd $INST_TOP/certs/Apache

$ORACLE_HOME/bin/orapki  cert display -cert Server_certificate.cer >/tmp/certificate_info

$ORACLE_HOME/bin/orapki  cert display -cert Server_certificate.cer |grep -i Valid > /tmp/cert_valid_txt

EXP_DATE=`cat /tmp/cert_valid_txt|cut -f2- -d':' |awk '$1=$1'`

TODAY_DATE=`date`

no_of_days_left=$(( ($(date -d "$EXP_DATE" +%s) - $(date -d "$TODAY_DATE" +%s) )/(60*60*24) ))

if [ $no_of_days_left -lt 30 ]

then

echo "-----------------------------------------------------------------------" >> /tmp/certificate_info

echo "Certificate is Going to Expire, Please get a new certificate and deploy" >> /tmp/certificate_info

mailx -s "Critical: `hostname -a` EBS Certificate is Going to Expire in 30 days" himanshu@funoracleapps.com< /tmp/certificate_info

fi
