目前版本是4.6.0

为什么跟pr的不一致呢

public static String decryptPriKeyByPKCS1(String encryptRandomKey, String msgAuditPriKey) throws Exception { String privateKey = msgAuditPriKey.replaceAll("(\r\n|\r|\n|\n\r)", "").replace("-----BEGIN RSA PRIVATE KEY-----", "").replace("-----END RSA PRIVATE KEY-----", "").replace(" ", ""); byte[] keyBytes = Base64.getDecoder().decode(privateKey); DerValue[] seq = (new DerInputStream(keyBytes)).getSequence(0); RSAPrivateCrtKeySpec keySpec = new RSAPrivateCrtKeySpec(seq[1].getBigInteger(), seq[2].getBigInteger(), seq[3].getBigInteger(), seq[4].getBigInteger(), seq[5].getBigInteger(), seq[6].getBigInteger(), seq[7].getBigInteger(), seq[8].getBigInteger()); PrivateKey priKey = KeyFactory.getInstance("RSA").generatePrivate(keySpec); Cipher cipher = Cipher.getInstance("RSA/ECB/PKCS1Padding"); cipher.init(2, priKey); byte[] utf8 = cipher.doFinal(Base64.getDecoder().decode(encryptRandomKey)); return new String(utf8, StandardCharsets.UTF_8); }
