What is a java keystore?

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

TA or Transaction analysis – Note

In Transactional Analysis, people communicate from three distinct ego states:

- Parent: Copies behaviours, feelings, and prejudices recorded from parental figures. It manifests as either critical (judging/scolding) or nurturing (comforting/protecting). [1, 2, 3, 4, 5]
- Adult: Functions like a data-processing computer. It operates in the present moment, analysing reality objectively and making logical, emotion-free decisions. [1, 2, 3, 4, 5]
- Child: Replays thoughts, feelings, and reactions experienced during early childhood. It can be natural (spontaneous/creative) or adapted (conforming/rebellious to past expectations). [1, 2, 3, 4, 5]
