Вот код .net 9, который создает саморегистрированный сертификат EC, сохраняется в файле .pem и пытается воссоздать сертификат из файла .pem .
// Generate ECC key pair
using var ecdsa = ECDsa.Create(ECCurve.NamedCurves.nistP256);
// Create certificate request
var req = new CertificateRequest(
"CN=MyECCert,O=MyOrg,C=US",
ecdsa,
HashAlgorithmName.SHA256);
// Create self-signed certificate
var cert = req.CreateSelfSigned(DateTimeOffset.UtcNow, DateTimeOffset.UtcNow.AddYears(1));
// Export certificate to PEM
string certPem = cert.ExportCertificatePem();
File.WriteAllText(certFilePath, certPem);
Console.WriteLine("Certificate exported to eccert.pem");
// Read PEM file
var certPemRead = File.ReadAllText(certFilePath);
// Load certificate from PEM
var certRead = X509Certificate2.CreateFromPem(certPemRead, null);
Console.WriteLine("Certificate loaded from PEM:");
Console.WriteLine(certRead.Subject);
< /code>
он не работает в строке: < /p>
var certRead = X509Certificate2.CreateFromPem(certPemRead, null);
with the following exception:
System.Security.Cryptography.CryptographicException: The key contents do not contain a PEM, the content is malformed, or the key does not match the certificate
What am I doing wrong?
Вот содержимое файла .pem < /code>: < /p>
