(VB.NET UWP/WinRT) RSA Sign with PKCS8 Encrypted KeySee more RSA ExamplesDemonstrates how to load a private key from an encrypted PKCS8 file and create an RSA digital signature.
' This example assumes the Chilkat API to have been previously unlocked. ' See Global Unlock Sample for sample code. Dim pkey As New Chilkat.PrivateKey ' Load the private key from an RSA PEM file: Dim success As Boolean = pkey.LoadPkcs8EncryptedFile("privateKey.key","myPassword") Dim pkeyXml As String ' Get the private key in XML format: pkeyXml = pkey.GetXml() Dim rsa As New Chilkat.Rsa ' Import the private key into the RSA object: success = rsa.ImportPrivateKey(pkeyXml) If (success <> True) Then Debug.WriteLine(rsa.LastErrorText) Exit Sub End If ' Return the signature in hex rsa.EncodingMode = "hex" Dim strData As String = "This is the string to be signed." ' Sign the string using the sha-1 hash algorithm. ' Other valid choices are "md2", "sha256", "sha384", "sha512", and "md5". Dim hexSig As String = rsa.SignStringENC(strData,"sha-1") Debug.WriteLine(hexSig) |
