How to use CAPI's CryptImportKey with PEM encode public key from OpenSSL?

How do I get the Microsoft's CryptoAPI CryptImportKey function to import a PEM encoded key? It actually works but CryptDecrypt returns an error. // 1. Generate a Public/Private RSA key pair like so: openssl genrsa -out private.pem 2048 openssl rsa -in private.pem -out public.pem -outform PEM -pubout // 2. Create [...] read more

I've written a script that'll create certificates for me and that should sign them all using another certificate. $dnsNames = @("example.com", "example.org") New-SelfSignedCertificate -CertStoreLocation Cert:\LocalMachine\My -DnsName $dnsNames -FriendlyName "Example Cert" -Signer Cert:\LocalMachine\Root\QWREEWRQ12123132QWEQWE123123 But when I run this script I get the error message CertEnroll::CSignerCertificate::Initialize: Key does not exist. 0x8009000d (-2146893811 [...] read more

Asymetric encryption algorithm which allows to use public and private key for both encryption and decryption

I have the following working asymetric encryption implementation: private static RSAParameters privateKey; private static RSAParameters publicKey; private static void RSA() { var rsa = new RSACryptoServiceProvider(); privateKey = rsa.ExportParameters(true); publicKey = rsa.ExportParameters(false); byte[] originalMessage = GenerateRandomData(); byte[] encryptedMessage = Using(publicKey).Encrypt(originalMessage, false); byte[] decryptedMessage = Using(privateKey).Decrypt(encryptedMessage, false); Debug.Assert(originalMessage.SequenceEqual(decryptedMessage)); } private static [...] read more
