(VB.NET) Generate RSA Public/Private Key Pair and Export to PEMVB.NET example code showing how to generate an RSA public/private key pair and export to PEM files.
' 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 1024-bit key. Chilkat RSA supports ' key sizes ranging from 512 bits to 4096 bits. Dim success As Boolean = rsa.GenerateKey(1024) If (success <> True) Then Debug.WriteLine(rsa.LastErrorText) Exit Sub End If ' Keys are exported in XML format: Dim publicKeyXml As String = rsa.ExportPublicKey() Debug.WriteLine(publicKeyXml) Dim privateKeyXml As String = rsa.ExportPrivateKey() Debug.WriteLine(privateKeyXml) ' Save the private key in PEM format: Dim privKey As New Chilkat.PrivateKey success = privKey.LoadXml(privateKeyXml) success = privKey.SavePemFile("privateKey.pem") ' Save the public key in PEM format: Dim pubKey As New Chilkat.PublicKey success = pubKey.LoadFromString(publicKeyXml) success = pubKey.SavePemFile(False,"publicKey.pem") |
