Converting KeyStore Files to PKCS12 Files

This section provides a tutorial example on how to convert a KeyStore file to a PKCS12 file, because Windows 'Internet Options' can import keys and certificates from PKCS12, but not from KeyStore file.

Let's assume that Amy has a private-public key pair and a certificate from me. She wants to add a digital signature on OpenOffice.org 3 document.

According to the OpenOffice.org 3 help text, Amy needs to import her private-public key pair and certificate using "Internet Option".

But there is problem. "Internet Option" can not import private-public key pair from KeyStore files. But it can import PKCS12 files.

So Amy needs to convert her KeyStore file to a PKCS12 file using the JDK "keytool" command:

C:\amy>\local\jdk\bin\keytool.exe -importkeystore -srckeystore amy.jks
   -srcstoretype jks -srcstorepass AmyJKS -srcalias amy@xyz.com  
   -destkeystore amy.p12 -deststoretype pkcs12 -deststorepass AmyP12 
   -destkeypass AmyP12

C:\amy>\local\jdk\bin\keytool.exe -list -keystore amy.p12 
   -storepass AmyP12 -storetype pkcs12

Keystore type: PKCS12
Keystore provider: SunJSSE

Your keystore contains 1 entry

amy@xyz.com, Mar 6, 2011, PrivateKeyEntry,
Certificate fingerprint (MD5): 00:5D:79:5A:47:76:C7:1A:53:3C:30:90...

Done. Amy now has her private-public key pair in a PKCS 12 file now. By the way her certificate is also included in that single PrivateKeyEntry.
