cfca工具包加解密问题

查看余e 2015-06-25 08:32:45

我用下面这种方法加解密，在加密的时候有四种加密算法供选择，然后当我用EnvelopUtil.DES3_CBC这种算法加密后解密会报错“850935: 解析消息数字信封失败 com.cfca.util.pki.cms.CMSException: key invalid in message.” 但是用其他三种算法就没有问题，想问问大神们这是怎么回事

    

    public static void main(String[] argv)

    {

        try

        {

        	Session session = null;// 加密库回话session对象

        		

        	byte[] fbisCer = null ;

        	byte[] Key = null ;

        		

            JCrypto jcrypto = JCrypto.getInstance();

    		jcrypto.initialize("JSOFT_LIB", null);

    		session = jcrypto.openSession("JSOFT_LIB");

    		

    		//读取公钥证书

    		InputStream is = jcrypto.getClass().getResourceAsStream("/fbis/"+"14.cer");

    		int len = is.available();

    		fbisCer = new byte[len];

    		is.read(fbisCer);

    		is.close();

    		//读取私钥匙证书

    	    is = jcrypto.getClass().getResourceAsStream("/fbis/"+"pfx_14.pfx");

            len = is.available();

            Key = new byte[len];

            is.read(Key);

            is.close();

            

            EnvelopUtil envUtil = new EnvelopUtil();

            X509Cert cert = new X509Cert(fbisCer);

            envUtil.addRecipient(cert);

            envUtil.setCMSFlag();

            byte[] b64MsgEnvelop = envUtil.envelopeMessage("aaaa".getBytes(), EnvelopUtil.DES3_CBC,

                    session);

            JKey priKey = KeyUtil.getPriKey(Key, "cmbc");

            // 数字信封接收者的公钥证书

            X509Cert cert1 = CertUtil.getCert(Key, "cmbc");

            // 根据私钥，公钥证书解密信息

            byte[] src = envUtil.openEnvelopedMessage(b64MsgEnvelop, priKey, cert1, session);

            

            System.out.println("tt:"+b64MsgEnvelop);

            System.out.println(new String(src));

        }

        catch (Exception e)

        {

            // TODO Auto-generated catch block

            e.printStackTrace();

        }

        

    }
