JKS stands for Java KeyStore. It is a repository of certificates (signed public keys) and [private] keys. You can export a certificate stored in a JKS file into a certificate file. You can use the keytool utility found in Java distributions to maintain your JKS trust and key repositories.
A .JSON file, or JavaScript Object Notation, is an open standard format that uses readable text to transmit data objects consisting of attribute-value pairs. The JSON file format is used to transmit structured data over various network connections. Mozilla JSON files created in a Firefox browser also contain backup copies of a user's bookmarks. Though .JSON was originally derived from the JavaScript scripting language, JSON is a language-independent data format.
