keytool error: java.io.FileNotFoundException: C:\cacerts (Access is denied)

Question

I am on Windows 10 with JRE8 and the command I'm using is:

C:\Program Files\Java\jre1.8.0_60\bin>keytool -keystore "C:\cacerts" -storepass changeit -importcert -file "C:\Users\MyUser\Desktop\sf.cer" -alias Symantec_Secure_Server_Class_3

Here's what I've tried so far:

1. Gave the cacerts file full access to my user (eventhough I am an admin)
2. Ran keytool as System Administrator in cmd
3. Put cacerts in different locations (even tried C:\cacerts)

I keep getting the same error:

Certificate was added to keystore keytool error: java.io.FileNotFoundException: C:\cacerts (Access is denied)

What else can I do to import this certificate into my cacerts file?

Solution 1

Try running the command line as administrator and do it again

Solution 2

Use the below command:

keytool -genkey -v -keystore test.keystore -alias testkeystore -keyalg RSA -keysize 2048 -validity 10000

the issue was that I was not giving the filename i.e. {test.keystore} which needs to be created as keystore file.

This will resolve the issue.

Solution 3

I ended up switching to another computer running Windows 8 with JRE7 and it worked!

UPDATE: Windows Defender was blocking access to the cacerts file. I disabled the brick wall tool and everything is good now!

Solution 4

Try putting on another drive: D:\tmp or C:\tmp (other than root).

Solution 5

If you are running keytool command on linux and facing similar issue, then run this keytool with sudo.

sudo keytool -genkey -alias amq-server -keyalg RSA -keystore amq-server.ks
