A Java Keystore (JKS) is a secure file container used by Java applications to store cryptographic keys, digital certificates, and trusted Certificate Authority (CA) certificates for SSL/TLS encryption.
As a Unix admin, you’ll manage it using the keytool utility. Here are the essential commands:
-
List contents:
keytool -list -v -keystore keystore.jks -
Import a certificate:
keytool -importcert -alias mydomain -file cert.crt -keystore keystore.jks -
Export a certificate:
keytool -exportcert -alias mydomain -file cert.crt -keystore keystore.jks -
Generate key pair:
keytool -genkeypair -alias mydomain -keyalg RSA -keystore keystore.jks
