(Xojo Plugin) Generate CSR from Pre-Existing Private KeyDemonstrates how to generate a Certificate Signing Request (CSR) from a pre-existing RSA private key. Note: This example requires Chilkat v9.5.0.65 or greater.
// Note: Requires Chilkat v9.5.0.65 or greater. // This requires the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. Dim privKey As New Chilkat.PrivateKey // Load the private key from a file. // (Chilkat provides the ability to load private keys from many different // formats and sources..) Dim success As Boolean success = privKey.LoadEncryptedPemFile("qa_data/rsa/privKey1.pem","password") If (Not success) Then System.DebugLog(privKey.LastErrorText) Return End If // Create the CSR object and set properties. Dim csr As New Chilkat.Csr // Specify the Common Name. This is the only required property. // For SSL/TLS certificates, this would be the domain name. // For email certificates this would be the email address. csr.CommonName = "mysubdomain.mydomain.com" // Country Name (2 letter code) csr.Country = "GB" // State or Province Name (full name) csr.State = "Yorks" // Locality Name (eg, city) csr.Locality = "York" // Organization Name (eg, company) csr.Company = "Internet Widgits Pty Ltd" // Organizational Unit Name (eg, secion/division) csr.CompanyDivision = "IT" // Email address csr.EmailAddress = "support@mydomain.com" // Create the CSR using the private key. Dim pemStr As String pemStr = csr.GenCsrPem(privKey) If (csr.LastMethodSuccess <> True) Then System.DebugLog(csr.LastErrorText) Return End If // Save the CSR..
