Generate RSA Key and return Base64 PKCS8 Private Key

See more RSA Examples

Demonstrates how to generate a new 2048-bit RSA private key and returns the Base64 encoded PKCS8 representation of the private key. Delphi ActiveX

var
success: Integer;
rsa: TChilkatRsa;
privKey: TPrivateKey;
privKeyPkcs8Base64: WideString;

begin
success := 0;

rsa := TChilkatRsa.Create(Self);

//  Generate a 2048-bit key.  Chilkat RSA supports
//  key sizes ranging from 512 bits to 8192 bits.
privKey := TPrivateKey.Create(Self);
success := rsa.GenKey(2048,privKey.ControlInterface);
if (success = 0) then
  begin
    Memo1.Lines.Add(rsa.LastErrorText);
    Exit;
  end;

//  Get the private key in PKCS8 Base64 format
privKeyPkcs8Base64 := privKey.GetPkcs8ENC('base64');

//  The key in base64 format will start similar to this:
//  MIIEvAIBADANBgkqhkiG9w0BA...
