[Jsdsi-users] KeyStore

[Dav C. <dav...@gm...>]

Hi,

I'm trying to save a Private Key and Certificate to a KeyStore and
then load it back. I'm able to create the keystore on the file system
without throwing any exceptions, but when I try to load it I get

java.security.cert.CertificateException: SPKI not found
        at java.security.cert.CertificateFactory.getInstance(CertificateFactory.java:191)
        at sun.security.provider.JavaKeyStore.engineLoad(JavaKeyStore.java:670)
        at java.security.KeyStore.load(KeyStore.java:652)
        at com.s0ciety.demo.CLI.loadKeyStore(CLI.java:129)

Any ideas on what would cause that?

Here is the (I hope) relevant code snippets

create and save keystore:

     pair = jsdsi.RSAPublicKey.create();
     java.security.PrivateKey privKey = pair.getPrivate();
     java.security.PublicKey pubKey = pair.getPublic();

      jsdsi.RSAPublicKey jsdsiPubKey = (jsdsi.RSAPublicKey)pair.getPublic();
     Date expire = new Date(now.getTime() + (86400 * 30));
     jsdsi.Validity validity = new jsdsi.Validity(now, expire);
     jsdsi.Cert cert = new jsdsi.NameCert(jsdsiPubKey, jsdsiPubKey,
validity, "display hint", "blah... comment field", "my jsdsi pubkey");
      jsdsi.Hash hash = new jsdsi.Hash("MD5", cert.toByteArray());
      jsdsi.Signature signature = null;
      jsdsi.Principal principal = (jsdsi.Principal) pair.getPublic();
      signature = jsdsi.Signature.create(pair, cert, "MD5withRSA");
      jsdsi.Certificate certificate = new jsdsi.Certificate(cert, signature);
      jsdsi.Certificate[] certificate_chain = new jsdsi.Certificate[]
{ certificate };
      // Create an empty keystore object
      keystore = KeyStore.getInstance(KeyStore.getDefaultType());
      keystore.load(null, password.toCharArray());  // null input
stream to create empty keystore
      keystore.setKeyEntry("myalias", privKey, password.toCharArray(),
certificate_chain);
      // Save the new keystore contents
      FileOutputStream out = new FileOutputStream(keystoreFile);
      keystore.store(out, password.toCharArray());
      out.close();

load keystore:

      FileInputStream fis = new FileInputStream(file);
      keystore = KeyStore.getInstance(KeyStore.getDefaultType());
      keystore.load(fis, password.toCharArray());
      fis.close();
      System.out.println("- keystore loaded");
      System.out.println("- contains "+keyStore.size()+" entries");


Are there any code examples available for integrating JSDSI into an
application? I've read a lot of docs and published papers online and I
think I have a basic understanding of SPKI/SDSI capabilities, but I'm
completely new to PKI application development so I feel a little lost.
