What is the default password for the Java user-level trusted certificate keystore: "trusted.certs"? I want to open it with "keytool" commands.

The default password for the Java user-level trusted certificate keystore "trusted.certs" is blank: "". Try the following "keytool" command:

C:\Users\fyicenter>"\Program Files\java\jre7\bin\keytool" -list
-storepass "" -keystore 
\Users\fyicenter\AppData\LocalLow\Sun\Java\Deployment\security\trusted.certs

Keystore type: JKS
Keystore provider: SUN

Your keystore contains 2 entries

my_cert, Jul 15, 2012, trustedCertEntry,
Certificate fingerprint (SHA1): 84:BB:46:36:12:75:9F:7C:02:BF:3B:D1:FA:83:74:4C:
58:2D:5D:81

Note that the last entry in "trusted.certs" keystore file is the "www.facebook.com" certificate I imported earlier using "Java Control Panel".
