What is a JKS file?

A JKS file is an encrypted security file used to store a set of cryptographic keys or certificates in the binary Java KeyStore (JKS) format. It requires a password to be opened.

More Information

Developers use JKS files for a variety of security-related purposes. For example, JKS files can be used as part of SSL encryption or to identify the author of an Android app. Because JKS files contain sensitive data, they are encrypted and password-protected.

NOTE: .KEYSTORE files also use the JKS format to store cryptographic keys and certificates.

How to open a JKS file

Provided you know a JKS file's password, you can open it and view its contents using KeyStore Explorer, a multiplatform app that allows users to create, import, export, and save various KeyStore files. Note that you must have the Java Runtime Environment installed in order to use KeyStore Explorer.
