This is very simple yet when I googled around I saw erratic answers such as ‘it is not possible’ or ‘you have to write java code’. As a matter of fact, keytool (a key management utility shipped in Sun’s JDK) lets you do it simply. What do you want to do? Convert alice.p12 to alice.jks Why do you want to do that? In Metro, a WS stack, it is common to use JKS as a format for storing private keys How do you convert then? See below Keytool’s documentation refers to the following option -importkeystore [-v] [-srckeystore ] [-destkeystore ] [-srcstoretype ] [-deststoretype ] [-srcstorepass ] [-deststorepass ] [-srcprotected] [-destprotected] [-srcprovidername ] [-destprovidername ] [-srcalias [-destalias ] [-srckeypass ] [-destkeypass […]
