C＃BouncyCastle PKCS＃8

Question

我想使用.net框架（而不是.netcore）加载PEM

-----BEGIN ENCRYPTED PRIVATE KEY-----
MIHs........................................................CAAw
DAYI........................................................gZAf
Y/Iu........................................................X7DZ
ZKoE........................................................OYQQ
3ZST........................................................A2E=
-----END ENCRYPTED PRIVATE KEY-----

• 我试图通过BouncyCastle使用以下代码，但它抛出PemException：“创建加密私钥的问题：Org.BouncyCastle.Crypto.InvalidCipherTextException：填充块已损坏”

 class Passowrd : IPasswordFinder
    {
        private string v;

        public Passowrd(string v)
        {
            this.v = v;
        }

        public char[] GetPassword()
        {
            return v.ToCharArray();
        }
    }

var pemReader = new PemReader(new StringReader(privateKeyText), new Passowrd("PASSWORD"));
var pemObj = pemReader.ReadObject(); // this line throw PemException

• 但是，我通过以下代码使用.netcore3.1加载了完全相同的PEM文件：

    var ecdsa = ECDsa.Create();
    ecdsa.ImportEncryptedPkcs8PrivateKey(passSpan, privateKeyBytes, out _);

Answer 1

您可以使用]阅读PEM。

var pemReader = new Org.BouncyCastle.OpenSsl.PemReader(new StringReader(privateKeyText), new Passowrd("PASSWORD"));
或

var pemReader = new Org.BouncyCastle.Utilities.IO.Pem.PemReader(new StringReader(privateKeyText));
然后阅读类似内容

var pemObject = pemReader.ReadPemObject();
