WebNov 20, 2024 · The private key has the SEC1 format and not the PKCS#8 format, i.e. the import must be done via ImportECPrivateKey().. The public key is an X.509/SPKI key, so ImportSubjectPublicKeyInfo() is correct.. Both methods expect a DER encoded key, i.e. without header and footer and Base64 decoded body. WebI've created a small helper NuGet package to create a X509 certificate based on public key and private (rsa) key. // Generate with: openssl req -x509 -sha256 -nodes -days 365 -newkey rsa:2048 -keyout private.key -out certificate_pub.crt string certificateText = File.ReadAllText ("certificate_pub.crt"); string privateKeyText = File.ReadAllText ...
ECDH public and private keys generation with .Net C#
WebFeb 2, 2024 · Public/private key pair. Asymmetrical cryptography is a technique that uses pairs of keys: A public key, visible to anyone. A private key, only known to the owner. The private key is essentially a randomly generated number. The public key can be derived from that public key using what’s called Elliptic Curve Cryptography. WebJun 29, 2024 · 1 Answer. The linked website generates private keys in PKCS#1 format and public keys in X.509/SPKI format, each PEM encoded. .NET Core only supports the import of PKCS#1 and X.509 keys as of version 3.0. For .NET Core 2.2, the easiest way is to apply BouncyCastle. For loading the PEM keys the PemReader of BouncyCastle can be used. four fluid ounces
