如何使用弹性城堡解密pkcs8加密私钥？ [英] How do i decrypt a pkcs8 encrypted private key using bouncy castle?

问题描述

你好我正在尝试使用bouncy castle library解密一个pkcs8加密的私钥。我使用bouncy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，我收到以下异常。

org.bouncycastle.pkcs.PKCSException：无法读取加密数据：1.2.840.113549.1.5。 13不可用：没有这样的提供者：1.2.840.113549.1.5.13

这里是我使用的代码

  PEMParser parser = new PEMParser（br）; 
 PKCS8EncryptedPrivateKeyInfo对=（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）; 
  

解决方案

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

Hi 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: unable to read encrypted data: 1.2.840.113549.1.5.13 not available: No such provider: 1.2.840.113549.1.5.13

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);

解决方案

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