Convert PFX to Java Trust Store with password

Hi Guys,

I am after some assistance. SSL Certificates is not my strong point.

Basically I have been passed a PFX certificate and I need to create a Java Trust Store file with a trust store password. I have been searching the net a struggling to find a good answer on this. (or I am just not searching for the correct terms)

I am on Windows 7 machine.

you can do this with the java keytool - first, get the cert name with the keytool:

keytool -v -list -storetype pkcs12 -keystore <pfx file name>

Open in new window

then, input that to keytool and output to jks:

keytool -importkeystore 
-srckeystore <pfx file name> -srcstoretype pkcs12 -srcalias <cert name from above>
 -destkeystore <jks file name> -deststoretype jks -deststorepass <new jks p/w> -destalias <same as cert name>

Open in new window

(all one command, should prompt for pfx password)

much easier is to use this gui tool though -

Hi Dave,

Do you know how to import this certificate then into the lib\security\cacerts file?

Sorry this is an area of unfamiliarity for me.


Dave HoweSoftware and Hardware EngineerCommented:
Well, you don't want to import the entire keypair, just the cert - but the procedure is pretty much the same. if you use the gui keytool, then export > keystore's entry > trusted certificate, pick the pfx file (pkcs#12) and specify a pem file to store it into. then similarly, import > keystore's entry > trusted certificate > root ca certificate. default password for the cacerts is "changeit" (no, not a joke!)

for the cli keytool, you would use:
keytool -export -keystore <pfx file name> -storetype pkcs12 -alias <cert name from before> -file tmp.pem

Open in new window

then to get it into cacerts:
keytool -import -keystore <cacerts keystore name>  -alias <cert name from before> -file tmp.pem

Open in new window

doing this is pretty unusual though. normally, you have a signed keypair AND a ca cert you want to import that signed that keypair.
