Hi All,
I am facing a problem while using security API in applets. What I am using is Bouncy Castle Crypto API. The exact place where I receive error is to encrypt and save the private key (I am pasting the code as well). This code worked fine in applet with IAIK API but giving problem with Bouncy Castle API.
/**********************************************?
private byte[] makeEncryptedPrivateKey(PrivateKey priKey, String password){
String alg = "1.2.840.113549.1.12.1.3";
PBEKeySpec pbeSpec = null;
SecretKeyFactory keyFact = null;
Cipher cipher = null;
byte[] wrappedKey = null;
byte[] encryptKey = null;
EncryptedPrivateKeyInfo pInfo = null;
try {
byte[] salt = new byte[10];
int iterationCount = 100;
PBEParameterSpec defParams = new PBEParameterSpec(salt, iterationCount);
AlgorithmParameters params = AlgorithmParameters.getInstance(alg, "BC");
params.init(defParams);
pbeSpec = new PBEKeySpec(password.toCharArray());
keyFact = SecretKeyFactory.getInstance(alg, UtilDefinitions.PROVIDER);
cipher = Cipher.getInstance(alg, UtilDefinitions.PROVIDER);
cipher.init(Cipher.WRAP_MODE, keyFact.generateSecret(pbeSpec), params);
wrappedKey = cipher.wrap(priKey);
pInfo = new EncryptedPrivateKeyInfo(params, wrappedKey);
encryptKey = pInfo.getEncoded();
}
catch (Exception ex) {
ex.printStackTrace();
}
return encryptKey;
}
When execution reaches at this method I receive the following error:
