Class PKCS12PfxPduBuilder

org.spongycastle.pkcs.PKCS12PfxPduBuilder

public class PKCS12PfxPduBuilder
extends java.lang.Object

A builder for the PKCS#12 Pfx key and certificate store.

For example: you can build a basic key store for the user owning privKey as follows:

      X509Certificate[] chain = ....
      PublicKey         pubKey = ....
      PrivateKey        privKey = ....
      JcaX509ExtensionUtils extUtils = new JcaX509ExtensionUtils();

      PKCS12SafeBagBuilder taCertBagBuilder = new JcaPKCS12SafeBagBuilder(chain[2]);

      taCertBagBuilder.addBagAttribute(PKCSObjectIdentifiers.pkcs_9_at_friendlyName, new DERBMPString("Bouncy Primary Certificate"));

      PKCS12SafeBagBuilder caCertBagBuilder = new JcaPKCS12SafeBagBuilder(chain[1]);

      caCertBagBuilder.addBagAttribute(PKCSObjectIdentifiers.pkcs_9_at_friendlyName, new DERBMPString("Bouncy Intermediate Certificate"));

      PKCS12SafeBagBuilder eeCertBagBuilder = new JcaPKCS12SafeBagBuilder(chain[0]);

      eeCertBagBuilder.addBagAttribute(PKCSObjectIdentifiers.pkcs_9_at_friendlyName, new DERBMPString("Eric's Key"));
      eeCertBagBuilder.addBagAttribute(PKCSObjectIdentifiers.pkcs_9_at_localKeyId, extUtils.createSubjectKeyIdentifier(pubKey));

      PKCS12SafeBagBuilder keyBagBuilder = new JcaPKCS12SafeBagBuilder(privKey, new BcPKCS12PBEOutputEncryptorBuilder(PKCSObjectIdentifiers.pbeWithSHAAnd3_KeyTripleDES_CBC, new CBCBlockCipher(new DESedeEngine())).build(passwd));

      keyBagBuilder.addBagAttribute(PKCSObjectIdentifiers.pkcs_9_at_friendlyName, new DERBMPString("Eric's Key"));
      keyBagBuilder.addBagAttribute(PKCSObjectIdentifiers.pkcs_9_at_localKeyId, extUtils.createSubjectKeyIdentifier(pubKey));

      //
      // construct the actual key store
      //
      PKCS12PfxPduBuilder pfxPduBuilder = new PKCS12PfxPduBuilder();

      PKCS12SafeBag[] certs = new PKCS12SafeBag[3];

      certs[0] = eeCertBagBuilder.build();
      certs[1] = caCertBagBuilder.build();
      certs[2] = taCertBagBuilder.build();

      pfxPduBuilder.addEncryptedData(new BcPKCS12PBEOutputEncryptorBuilder(PKCSObjectIdentifiers.pbeWithSHAAnd40BitRC2_CBC, new CBCBlockCipher(new RC2Engine())).build(passwd), certs);

      pfxPduBuilder.addData(keyBagBuilder.build());

      PKCS12PfxPdu pfx = pfxPduBuilder.build(new BcPKCS12MacCalculatorBuilder(), passwd);
