TLDR

Modify your keystore and key passwords using these keytool commands:

# Update keystore password. Just like changing your house door lock 🗝️: keytool -storepasswd -keystore mykeystore.jks # Modify key password. Remember, it's like updating your diary's secret lock 🔒: keytool -keypasswd -alias mykey -keystore mykeystore.jks

Be sure to replace mykeystore.jks with your keystore's filename and mykey with your key alias. To continue, you need to input your original passwords, followed by the new ones.

Safe Practices for Keystore Modification

Preparing for a password change

Your precious keystore is sensitive— hence always backup your keystore like a relentless hoarder, before you touch any passwords. Remember, Ctrl+Z doesn't exist in real life.

The danger of mistypes

Typographical errors are everyone's worst nightmare. Ensure the keystore and alias names are correct— a careless typo could slam your access door shut.

Shell history - A double-edged sword

Beware of command history or variable scripts while using keytool. Your passwords exposed here are like footprints on a snow-covered field, easily traceable.

Distributing new passwords (Non-DIY style)

If you need to distribute the new passwords, be our generation's James Bond. Don't use plain text or chat logs — use encrypted emails or password managers, they are your best friends.

Efficient Workflow Practices

The underrated hero - Backups

Backup, backup, backup! Backup is the unsung hero, your knight in shining armor whenever you fumble. Keeping one is as essential as breathing. Ignore the loud "Risk Ahead!" signs at your own peril.

Post-password change rituals

Once the password is changed, it's time to test the waters. Checking the keystore functionality after modification is as important as remembering the birthday of your significant other.

Shared access - A hassle free way

Office politics, sigh! If your organization has many people needing the keystore at the same time, consider using role-based access or creating additional keystores. Shared passwords sometimes equal chaos.

Automation - The modern genie

Are you a frequent password changer? Allow scripts to become your modern genie. But be clever and handle passwords securely— you don’t want a lurking Jafar to steal them.

Best Practices Post-Change

Tread on security, not eggshells

Changing the keystore password is not akin to walking on eggshells, but it demands your attention. Foil your enemy's plot by being attentive about your keys' security at all times.

Keep your secrets, secret

Passwords and insecure coding are a toxic relationship. Stop rekindling it. Don't hardcode passwords. Let the Prince charm his princess with encrypted or obfuscated dynamic passwords.

All clear from the control room

Before you change the password, check with control (your permissions). You don’t fancy being chained inside Azkaban for intruding into someone else's property.

The aftermath

You changed the password, congratulations! Now, relay the news to your team and dependent services. Let's bask in the cheer rather than play hangman with configurations.
