Keystore / Truststore commands

1. Use this command to install a cert in the default JVM truststore

keytool -import -alias myalias -file /path/to/cert/mycert.cer -keystore $JAVA_HOME/jre/lib/security/cacerts -storepass changeit

2. Use this command to install a cert in the custom JVM truststore

(Note: use the javax.net.ssl.trustStore= System Property in the java app to use the custom TrustStore.)

keytool -import -alias myalias -file /path/to/cert/mycert.crt -keystore ./mykeyStore  -storepass 123456

Examples

keytool -import -alias httpbinorg -file /Users/paulmyers/Desktop/httpbinorg.crt -keystore ./keyStore -storepass 123456

keytool -import -alias adobecqmsnet -file /Users/paulmyers/Desktop/adobecqmsnet.crt -keystore ./keyStore -storepass 123456

NOTE: use the -trustcacerts option to include the root CA cert in the truststore.

3. List certs in a keystore

keytool -list -v -keystore keystore.jks

4. Use openssl to look dump the data in a cert:

openssl x509 -noout -text -in myCert.crt
