Question

我有一个使用AES256和密钥salam加密的私钥。

我想解密它并读取其中的私钥。

我写下代码：

public CertReader(String password, Context context) {
        mContext = context;
        pf = new Password(password.toCharArray());
        InputStream Certin = mContext.getResources().openRawResource(
                R.raw.kxx_2048_sign);
        PEMReader pemRd = openPEMResource(Certin, pf);
        Object o = null;

        try {
            o = pemRd.readObject();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        X509Certificate x509 = ((X509Certificate) o);
        logging.l(x509.toString());

        Certin = mContext.getResources().openRawResource(
                R.raw.kxx_2048);
        pemRd = openPEMResource(Certin, pf);
        try {
            o = pemRd.readObject(); //My Program exit with error here.
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        // KeyPair key = ((KeyPair)o);
        // logging.l(key.toString());

    }

    private PEMReader openPEMResource(InputStream Certin, PasswordFinder pGet) {
        Reader fRd = new BufferedReader(new InputStreamReader(Certin));
        return new PEMReader(fRd, pGet);
    }

    private static class Password implements PasswordFinder {
        char[] password;

        Password(char[] word) {
            this.password = word;
        }

        public char[] getPassword() {
            return password;
        }
    }

kxx_2048_sign.crt是一个证书，它没有问题，因为它没有加密。

但kxx_2048.key已使用AES256进行加密，而在o = pemRd.readObject();我收到了以下错误：

 java.lang.IllegalAccessError: tried to access class org.bouncycastle.openssl.PEMUtilities from class org.bouncycastle.openssl.PEMReader$KeyPairParser

重点开始：

-----BEGIN RSA PRIVATE KEY-----
Proc-Type: 4,ENCRYPTED
DEK-Info: AES-256-CBC,5C76FCD87.....

有什么问题？

我在PC上检查了它并且它工作正确但在Android中它不起作用。

如何在android中读取带有bouncycastle的Cipher私钥？
