If you do have Keytool application and your PKCS#12 file, launch the one-line command:
keytool -importkeystore -srckeystore [MY_FILE.p12] -srcstoretype pkcs12
-srcalias [ALIAS_SRC] -destkeystore [MY_KEYSTORE.jks]
-deststoretype jks -deststorepass [PASSWORD_JKS] -destalias [ALIAS_DEST]
You’ll need to modify these parameters:
MY_FILE.p12: indicate the path to the PKCS#12 file (.p12 or .pfx extension) to be converted.MY_KEYSTORE.jks: path to the keystore in which you want to store your certificate. If it does not exist it will be created automatically.PASSWORD_JKS: password that will be requested at the keystore opening.ALIAS_SRC: name matching your certificate entry in the PKCS#12 file, “tomcat” for example.
In case you would export your certificate from a Windows server generating a .PFX file, you’ll have to retrieve the “alias” name created by Windows. To do so, you can execute the following command:
keytool -v -list -storetype pkcs12 -keystore FILE_PFX
There, the “alias name” field indicates the storage name of your certificate you need to use in the command line.
ALIAS_DEST: name that will match your certificate entry in the JKS keystore, “tomcat” for example.
