Greg,
Thanks for your help. I am using the Sun's classes for my application.
KeyStore keyStore;
byte[] bytes;
X509Certificate[] certs = new X509Certificate[2];
I am calling this function
keyStore.setKeyEntry("testKey", bytes, certs); and it is throwing
exceptions.
java.lang.NullPointerException
at
sun.security.pkcs.EncryptedPrivateKeyInfo.<init>(EncryptedPrivateKeyInfo.java:63)
at
sun.security.provider.JavaKeyStore.engineSetKeyEntry(JavaKeyStore.java:275)
at java.security.KeyStore.setKeyEntry(KeyStore.java:395)

Srini,
What sorts of exceptions are you getting? Of course you need to use the
same password for reading the key in that you used to write it out. The
default encryption algorithm used by the pkcs8 utility is
pbeWithMD5AndDES-CBC, so this must be available to the Java code you are
importing the key with. Here is a very short example that uses the IAIK JCE
2.6 classes and provider.
/***
* Suppose the following commands are run:
* openssl genrsa -out key.pem
* openssl pkcs8 -topk8 -outform DER -in key.pem -out enckey.der -passout
pass:PASSWORD
* Then run this program as:
* java TestPKCS8 enckey.der PASSWORD
*/
import iaik.asn1.DerCoder;
import iaik.asn1.ASN1Object;
import iaik.pkcs.pkcs8.EncryptedPrivateKeyInfo;
import java.io.FileInputStream;
import java.security.PrivateKey;
public class TestPKCS8 {
public static void main(String [] args)
{
try{
iaik.security.provider.IAIK.addAsProvider();
ASN1Object enckey = DerCoder.decode(new FileInputStream(args[0]));
PrivateKey key = new EncryptedPrivateKeyInfo(enckey).decrypt(args[1]);
System.out.println(key);
} catch(Exception e) {
e.printStackTrace();
}
}
}
