.JCEKS File Extension
What is a JCEKS file?
Keystore file saved in the Java Cryptography Extension KeyStore (JCEKS) format; used as an alternative keystore to the Java Keystore (JKS) format for the Java platform; stores encoded keys and certificates that are referenced by a Java program.
JCEKS files may be used to verify an Android app developer when publishing an app or sending out updates. It also may be used to encrypt SSLs. The file requires a password to be accessed.
NOTE: The JCEKS format is similar to the JKS format used by JKS files but uses Triple DES encryption for stronger protection.
