(C#) RSA Encrypt and OpenSSL Decrypt

Demonstrates how to use Chilkat to RSA encrypt, and then use OpenSSL to decrypt.

Chilkat .NET Downloads Chilkat .NET Framework Chilkat for .NET Core

//  This requires the Chilkat API to have been previously unlocked.
//  See Global Unlock Sample for sample code.

Chilkat.Rsa rsa = new Chilkat.Rsa();

bool success = rsa.GenerateKey(2048);

Chilkat.PrivateKey privKey = rsa.ExportPrivateKeyObj();
success = privKey.SavePkcs8PemFile("qa_output/privKey.pem");

rsa.EncodingMode = "base64";
string plainText = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz01234567890";
bool bUsePrivateKey = false;
string encryptedStr = rsa.EncryptStringENC(plainText,bUsePrivateKey);

Chilkat.BinData bd = new Chilkat.BinData();
bd.AppendEncoded(encryptedStr,"base64");
success = bd.WriteFile("qa_output/enc.dat");

//  The OpenSSL command to decrypt is:
//  openssl pkeyutl -in enc.dat -inkey privKey.pem -keyform PEM -pkeyopt rsa_padding_mode:pkcs1 -decrypt

Debug.WriteLine("OK");
