(Xojo Plugin) Generate an RSA Key and Get as Base64 DERDemonstrates how to generate a 2048-bit RSA key and return the public and private parts as unencrypted Base64 encoded DER. Note: This example requires Chilkat v11.0.0 or greater.
Dim success As Boolean success = False // This example assumes the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. Dim rsa As New Chilkat.Rsa // Generate a 2048-bit key. Dim privKey As New Chilkat.PrivateKey success = rsa.GenKey(2048,privKey) If (success = False) Then System.DebugLog(rsa.LastErrorText) Return End If // Get the public part of the key. Dim pubKey As New Chilkat.PublicKey success = privKey.ToPublicKey(pubKey) // There are two possible formats for representing the RSA public key // in ASN.1 (DER). The possible formats are PKCS1 and PKCS8. // We can get either by setting bChoosePkcs1 to True or False. Dim bChoosePkcs1 As Boolean bChoosePkcs1 = True Dim pubKeyBase64Der As String pubKeyBase64Der = pubKey.GetEncoded(bChoosePkcs1,"base64") System.DebugLog("Public Key Base64 DER:") System.DebugLog(pubKeyBase64Der) // Get the private key as Base64 DER: // We can get PKCS1 or PKCS8, but with different methods: Dim privKeyPkcs1 As String privKeyPkcs1 = privKey.GetPkcs1ENC("base64") System.DebugLog("Private Key PKCS1 Base64 DER:") System.DebugLog(privKeyPkcs1) Dim privKeyPkcs8 As String privKeyPkcs8 = privKey.GetPkcs8ENC("base64") System.DebugLog("Private Key PKCS8 Base64 DER:") System.DebugLog(privKeyPkcs8) |
