Converting a Java Keystore into PEM Format
Here's a quick and dirty way to convert a Java Keystore to PEM. You need two tools: keytool and openssl.
Need to get your hands on the private key as well, in PEM format?
Remember to replace my_boring_alias, boring_keystore.jks, your_semi_red_hot_chili_peppers_password, and same_chili_pass_as_above with your actual alias, keystore filename, and corresponding passwords.
Step-by-step guide and use cases
Transmuting a Java Keystore to PEM format is no dark art. It calls for extracting certificates and keys, followed by a magical spell that alters their metaphysical readability for those apps and services demanding PEM files.
Variations in key extraction
The alias is the keystore's guardian. Pick the right one while extracting entries from your keystore, unless you prefer to dump the whole lot. Specific scenarios might require extraction and conversion of a lone knight rather than the entire army. Choose your warrior correctly in your battle commands.
The direct route
Direct extraction of the certificate in PEM format can be made reverently easy with the -rfc flag, offering a transcendent path, eliminating the need for intermediate vessel of conversion.
Keystone of security
It's a cold cruel world out there, protect your journey through the conversion process by securing it with strong and unique passwords for each leg of the journey. Touch the divine regularly by validating the converted sacred scripts to bring peace and order to their new reality.
Troubleshooting common speed bumps
Life is but a dream with an obstinate alarm clock named troubleshooting. So, check your keystore access permissions regularly as they pose a significant influence over your divine journey and the consequential security. Should clouds of doubt hover over you, seek enlightenment from online communities.
Navigating the mystical path
In this astral journey, every stone is different. Distinct entrances require unique attunement for key and certificate management. While the sacred Java laws forbid the direct exportation of the private key in its chosen form, PEM, a bardic tale whispers of a path involving the creation of a PKCS#8 format through divine Java scriptures, to be later transformed into the chosen format of PEM, using the blessing of openssl.
Post-transmutation key differentiation
After the incantation, the PEM file may contain both, the holy relic and the sacred manifestation, the certificate and the private key. However, your divine mission may require you to separate these two into unique scriptures, each for its purpose in your grand design. Fear not, for you possess the divine tool of openssl, that bestows you with the power to create new realities out of the old.
