PrivateKey rdKey = (PrivateKey) pRd.readObject(); assertEquals(key, rdKey); }示例三 转换 rsa的私钥为 pem 字符串/* * 转换 rsa的私钥为 pem 字符串 * * @param rsaKeyPair RSA 类型keypair * @return PEM string / public static String getPEMStringFromRSAKeyPair(RSAKeyPair rsaKeyPair) { StringWriter pemStrWriter = new StringWriter(); PEMWriter pemWriter = new PEMWriter(pemStrWriter); try { KeyPair keyPair = new KeyPair(rsaKeyPair.getPublic(), rsaKeyPair.getPrivate()); //pemWriter.writeObject(keyPair); pemWriter.writeObject(keyPair.getPrivate()); //pemWriter.flush(); pemWriter.close(); } catch (IOException e) { log.warning(“Caught exception:” + e.getMessage()); return “”; } return pemStrWriter.toString(); }示例四 将pem 数据对象转换成 pem格式文件数据/* * 将pem 数据对象转换成 pem格式文件数据 * @param object * @return * @throws IOException */ public static byte[] toPem(Object object) throws IOException { ByteArrayOutputStream outputStream = new ByteArrayOutputStream(); try (PEMWriter writer = new PEMWriter(new OutputStreamWriter(outputStream))) { writer.writeObject(object); writer.flush(); return outputStream.toByteArray(); } }示例五 将多份 certificate 对象写入文件private void writeCertificate(Certificate… certificates) throws IOException { final PEMWriter writer = new PEMWriter(new FileWriter(destfile)); for (final Certificate c : certificates) { writer.writeObject(c); } writer.close();}示例六 将 X509Certificate 转换成 pem格式数据public String x509CertificateToPem(final X509Certificate cert) throws IOException { final StringWriter sw = new StringWriter(); try (final PEMWriter pw = new PEMWriter(sw)) { pw.writeObject(cert); } return sw.toString();}示例七 将 rsa私钥对象转换为 PEM 格式数据public String rsaPrivateKeyToPem(final PrivateKey key) throws IOException { final PemObject pemObject = new PemObject(CCS_RSA_PRIVATE_KEY, key.getEncoded()); final StringWriter sw = new StringWriter(); try (final PEMWriter pw = new PEMWriter(sw)) { pw.writeObject(pemObject); } return sw.toString();}示例八 将私钥、证书文件等转换为 PEM数据private static byte[] getPemBytes(Object… objects) throws Exception { ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream(); try (PEMWriter pemWriter = new PEMWriter(new OutputStreamWriter(byteArrayOutputStream, UTF_8))) { for (Object object : objects) { pemWriter.writeObject(object); } } return byteArrayOutputStream.toByteArray();}示例九 将 X509Certificate 转换为PEM 数据private static String toPem(X509Certificate certificate) throws IOException { StringWriter stringWriter = new StringWriter(); PEMWriter pemWriter = new PEMWriter(stringWriter, BouncyCastleProvider.PROVIDER_NAME); pemWriter.writeObject(certificate); pemWriter.close(); return stringWriter.toString();}示例十 将多个 证书数据 写入文件private void writeCertificate(Certificate… certificates) throws IOException { final PEMWriter writer = new PEMWriter(new FileWriter(destfile)); for (final Certificate c : certificates) { writer.writeObject(c); } writer.close();}示例十一 将keyPair 转换成Pem格式private String keyPairToString(KeyPair keyPair) { StringWriter stringWriter = new StringWriter(); PEMWriter pemWriter = new PEMWriter(stringWriter); try { pemWriter.writeObject(keyPair); pemWriter.flush(); pemWriter.close(); } catch (IOException e) { throw new RuntimeException(“Unexpected IOException: " + e.getMessage(), e); } return stringWriter.getBuffer().toString();}
