本文介紹了InvalidKeySpecException:algid 解析錯(cuò)誤，不是序列的處理方法，對(duì)大家解決問(wèn)題具有一定的參考價(jià)值，需要的朋友們下面隨著小編來(lái)一起學(xué)習(xí)吧！

問(wèn)題描述

我正在編寫一個(gè)程序，它接受來(lái)自控制臺(tái)的輸入 - zip 文件的名稱、要制作的 zip 文件的名稱，其中包含從第一個(gè) zip 生成的(de/en)加密文件和一個(gè)包含公鑰.解密時(shí)出現(xiàn)異常:

解決方案

您的私鑰不是 PKCS#8 格式.您必須向其添加關(guān)鍵算法信息以使其成為 PKCS#8，然后它才能工作.

您可能應(yīng)該更改生成密鑰的方式，以使它們采用 PKCS#8 格式.但由于我對(duì)此一無(wú)所知，我將只展示如何使用 BouncyCastle 庫(kù)在您的應(yīng)用程序中更新密鑰:

I'm writing a program which takes as input from the console - the name of a zip file, name of a zip file to be made containig the (de/en)crypted files generated from the first zip and a file containing the public key. I get the exception when decrypting:

Can't figure out why because the I use the rigth spec in the makePrivateKey method. The keys I'm testing with are(one line for a key each in a separate file):

解決方案

Your private key is not in PKCS#8 format. You have to add key algorithm information to it to make it PKCS#8 and then it will work.

Probably you should alter the way you generate keys to have them in PKCS#8 format. But since I know nothing on that I will just show how to update key to it in your application using BouncyCastle library:

@Test
public void testKey() throws Exception {
    String privKeyStr = "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";
