Guys, I have been facing multiple challenges with getting the ManagedOpenSsl to work with .Net Core. I downloaded ManagedOpenSsl.NetCore from nuget package.

My end goal is to create a .pfx file from certificate PEM and private key. In the below code, ocert.KeyPair.PrivateKey is the certificate private key and ocert.CertificatePem is the certificate PEM.

ManagedOpenSsl.NetCore.Core.BIO key_bio = new ManagedOpenSsl.NetCore.Core.BIO(ocert.KeyPair.PrivateKey);
            ManagedOpenSsl.NetCore.Core.BIO cert_bio = new ManagedOpenSsl.NetCore.Core.BIO(ocert.CertificatePem);

            ManagedOpenSsl.NetCore.Crypto.CryptoKey key = ManagedOpenSsl.NetCore.Crypto.CryptoKey.FromPrivateKey(ocert.KeyPair.PrivateKey, "xxxxx");
            ManagedOpenSsl.NetCore.X509.X509Certificate cert = new ManagedOpenSsl.NetCore.X509.X509Certificate(cert_bio);
            ManagedOpenSsl.NetCore.Core.Stack<ManagedOpenSsl.NetCore.X509.X509Certificate> hmm = new ManagedOpenSsl.NetCore.Core.Stack<ManagedOpenSsl.NetCore.X509.X509Certificate>();

            var pfx = new ManagedOpenSsl.NetCore.X509.PKCS12(password, key, cert, hmm); // <-- 
            ManagedOpenSsl.NetCore.X509.X509Certificate certpfx = pfx.Certificate;

I'm getting error {System.TypeInitializationException: The type initializer for 'ManagedOpenSsl.NetCore.Core.Native' threw an exception. ---> System.BadImageFormatException: An attempt was made to load a program with an incorrect format. (Exception from HRESULT: 0x8007000B) at ManagedOpenSsl.NetCore.Core.Native.SSLeay() at ManagedOpenSsl.NetCore.Core.Version.get_Library() at ManagedOpenSsl.NetCore.Core.Native..cctor() --- End of inner exception stack trace - in the line of code `ManagedOpenSsl.NetCore.Core.BIO key_bio = new ManagedOpenSsl.NetCore.Core.BIO(ocert.KeyPair.PrivateKey);

I have set the Platform Target to "Any CPU", still the issue occurs. Also any implementation on how to save the pfx.Certificate to a specific folder in .pfx format ? Any help will be appreciated. Been struggling with this issue for a while now.
