What is the most effective approach for exporting and importing public and private keys in C# .Net 6 Asymmetric encryption?

edit

The most effective approach for exporting and importing public and private keys in C# .NET 6 for Asymmetric encryption is to use the standard PKCS#8 format for private keys and X.509 certificate format for public keys.

To export the private key, you can use the ExportPkcs8PrivateKey method from the System.Security.Cryptography namespace. This method allows you to export the private key in PKCS#8 format, which can be easily exchanged between different systems.

To import the private key, you can use the ImportPkcs8PrivateKey method from the same namespace, which will allow you to import the private key in PKCS#8 format.

To export the public key, you can use the ExportSubjectPublicKeyInfo method from the System.Security.Cryptography namespace. This method allows you to export the public key in X.509 format, which is a widely used standard format for public keys.

To import the public key, you can use the ImportSubjectPublicKeyInfo method from the same namespace, which will allow you to import the public key in X.509 format.

Overall, following these standard formats for exporting and importing public and private keys ensures interoperability with other systems and provides a secure approach for exchanging keys.
