如何使用充气城堡解密pkcs8加密私钥？ [英] How to decrypt a pkcs8 encrypted private key using bouncy castle?

问题描述

我正在尝试使用弹性城堡库解密pkcs8加密的私钥。我使用充气城堡提供的 PEMParser 解析了包含私钥的文件。我得到了 PKCS8EncryptedPrivateKeyInfo 对象。我无法从中获取 PrivateKeyInfo 对象。
尝试解密时遇到以下异常。

i am trying to decrypt a pkcs8 encrypted private key using bouncy castle library. I parsed the file containing the private key using PEMParser provided by bouncy castle. I got PKCS8EncryptedPrivateKeyInfo object. I am unable to get the PrivateKeyInfo object from this. I am getting the following exception while trying to decrypt.

org.bouncycastle.pkcs.PKCSException：无法读取加密的数据：1.2.840.113549.1.5.13不可用：没有此类提供者：1.2.840.113549.1.5.13

org.bouncycastle.pkcs.PKCSException: unable to read encrypted data: 1.2.840.113549.1.5.13 not available: No such provider: 1.2.840.113549.1.5.13

这是其中的代码我使用了

here is the code which I used

PEMParser parser = new PEMParser(br);
PKCS8EncryptedPrivateKeyInfo pair =       (PKCS8EncryptedPrivateKeyInfo)parser.readObject();
JceOpenSSLPKCS8DecryptorProviderBuilder jce = new JceOpenSSLPKCS8DecryptorProviderBuilder();
                jce.setProvider("1.2.840.113549.1.5.13");
                InputDecryptorProvider decProv = jce.build(password.toCharArray());
                PrivateKeyInfo info = pair.decryptPrivateKeyInfo(decProv);

推荐答案

您是否尝试过使用jce.setProvider（ BC ）;而不是jce.setProvider（ 1.2.840.113549.1.5.13）;

Have you tried with jce.setProvider("BC"); instead of jce.setProvider("1.2.840.113549.1.5.13");

编辑以添加@PeterDettman提供的解决方案：

除了使用jce.setProvider（ BC）;还安装BC提供程序 bouncycastle.org/wiki/display/JA1/Provider+Installation

In addition to use jce.setProvider("BC"); also install the BC provider bouncycastle.org/wiki/display/JA1/Provider+Installation
